ch65a7 | How does different spf’s on sunscreen (sublock) affect the tan you get? | It blocks the UV B rays which cause you to tan. The higher the SPF, the more it blocks the UV rays.

ch669h | Why does metal bend but stone break? | Metals stay together more or less electromagnetically. All of the metal atoms are packed tightly enough their electrons are constantly switching around between them, which makes for a very strong, but also somewhat malleable material. There's not really any specific structure to them at the atomic level.
Rocks on the other hand, tend to have more crystalline matrixes. Their structures are sturdy but very specific at the atmoic level. These matrixes can't really change shape or reaarange themselves, so rather than bending, they break. | 9bc775fe-f1b8-4999-8759-604f0e3da3be |
ch69sn | Why Does English Have So Many Strange And Varied Collective Nouns For Animals? | > These just seem like jokes
Pretty much, yes. [Terms of venery](_URL_0_) are essentially an in-joke from the 1400s that happened to get written down. Some modern English speakers like them, most don't know about them. | db622da9-5c80-48ae-8d74-4caef842adc2 |
ch6uce | How do synthesizers work? | A synthesizer can make all kinds of interesting noises. It does this with the help of modules.
Modules have inputs, outputs and sometimes also settings that can be changed.
Connecting the outputs of modules to the input of (other) modules as well as changing the settings of those modules creates a 'patch'.
A 'patch' is what determines how the synthesizer will sound and people will sometimes share (describe) their patches with other people so that they can also get the same sound. (Normally people need the same synthesizer to do this but there are exceptions.)
& #x200B;
There are different types of modules;
\- An oscillator produces a signal that can be changed in shape (waveform), pitch (frequency) and volume (amplitude).
\- A filter takes a signal and changes how the signal 'sounds' by changing how loud or soft frequencies in a signal appear; filters make a signal sound warmer or colder.
\- A VCA takes a signal and makes it louder or softer with the help of another signal.
\- An envelope generator produces a signal that people use to create sounds that change over time; they are often used in combination with a VCA and/or filter to create sounds that 'imitate' plucked strings, brass instruments or percussion instruments.
\- and much more...
& #x200B;
To summarize; Modules can be seen as building blocks that create, change or do things with the help of signals.
& #x200B;
In modular synthesizers the modules are physical; you place them in a rack and use cables to connect inputs and outputs together.
& #x200B;
In most synthesizer keyboards the modules are not physical and you use the screen and/or buttons to create patches.

ch74o9 | how a blister is formed. | Something causes a break between the layers of the skin - like heat that breaks connections between layers, or movement that mechanicaly tears it. The inner layers are living tissue, and so contain 'lumph'- the fluid that surrounds all living cells. This lymph pushes open that break made between layers, pushing the layers apart.
This is fine, however - left alone, the lower layer will seal over and become strong skin, the lymph will slowly be reabsorbed or leach through the skin, the top layer will dry up and flake off, leaving new, healthy skin. As long as the blister is left in tact. | 8b1657d0-fb4e-485a-b904-993c5081b48a |
ch7eaa | What decides the volume and duration of a thunder clap? | Imagine the soundwave/shockwave of thunder like an invisible cylinder around the lightning you just saw. That cylinder is created at the moment you see lightning, and it grows in radius at the speed of sound (approx. 300m/s). Now on the surface of that cylinder there are one thousand of tiny little surfers, each of the surfing in their own direction away from the lightning, and whenever a surfer collides with your ear, you hear a noise.
Now, as the cylinder grows, all of the surfers naturally surf away from each other, and all the surfers grow further and further apart (or less and less energy per surface area). The less surfers reach your ear, the more quiet the thunder.
The duration of thunder is a little bit harder to imagine. Again, a thousand surfers riding the shockwave. In their path from the lightning outwards, some of the surfers hit rigid objects like walls, houses, rocks, or trees. These rigid surfaces reflect them away from their original path. But if they cross a city, they don't only hit one house, but many. They end up on sort of a crazy random walk through the city, reflected hundreds to thousands of times. But in the end they may still end up in someones ear, and that person can again hear a tiny noise.
Now as I said there a thousands of surfers, and all of them are randomly reflected a different number of times, so they take a different amount of time until they can be heard. Hence the once short, loud bang (many surfers arriving all at the same time) became a long, less loud rumble (many surfers all arriving one after another).
Edit: Gold? For a bunch of surfers? Thank you kind stranger! | 6da5dc87-ebd3-4c51-81ad-c442938ecbc3 |
ch7jeo | Why do England, Wales, Scotland and NI compete in world cups but join together for the Olympics? | Many popular sports originated in the UK, so the first "international" competitions were between the nations within the UK.
Now many other countries take part, but the idea that the UK nations compete separately has been grandfathered in. For example FIFA has an explicit rule that each of the four "British Associations" are members in their own right despite not being independent countries.
However the Olympics involved many countries right from the start. So it was a team per sovereign state (more or less, some dependent territories have their own teams). | ccedf9ff-1995-4e4b-9f76-6c4645e23d21 |
ch7k21 | Equality vs Equity | Think of "equity" as "fairness".
Now, imagine you are a teacher, and one of your students comes up to you saying they have cut their finger so you give them a bandaid. The next child comes up to you saying they have a headache so you give them a bandaid. Another student says they miss their parents, so you give them a bandaid.
You gave the exact same thing to every child in need (equality), but only one child was actually helped. It was unfair treatment even though it was equal.
Equality doesn't always mean equity. Sometimes to be fair, you need to treat people/groups differently based on their needs. | 01f3e256-f8d2-4c08-af1d-c834153ef45c |
ch7lba | what keeps our bodies from decomposing before we die? | You can absolutely start decomposing while alive! We call this necrosis and it smells absolutely revolting
When a cell is faced with some kind of stressor, such as bacterial/viral infection, injury, chemical changes, etc., its membrane dissolves and it basically explodes. If a bunch of cells explode in sequence, you end up with a dead area of tissue. This is because when the initial cell explodes, it releases inflammatory and corrosive compounds that affect other, healthy cells. People can survive with incredible amounts of necrosis; I've seen patients with partially mummified extremities still attached to their bodies. Necrosis can occur just about anywhere in the body.
What determines subsequent death is how critical the necrotizing tissue is for life, as well as the propensity for infection. Necrotizing tissue can spread infection and even alter the pH of neighboring tissue. More often than not, infection or more specifically sepsis, will claim the person's life.
The body does perform a regulated version of necrosis called apoptosis. This can be thought of as a "scheduled cell death". Some cells that complete their life cycle undergo programmed death. This is how we can more or less "regenerate" an organ every few years, without it getting bigger. We also see apoptosis during the development of a fetus (that's why we don't have webbed skin between our fingers!). The difference is that with apoptosis, cell contents remain within the deceased cell membrane and only scheduled cells die.

ch7r9y | Is there a Radio Frequency Camera? | Yes, but the resolution is limited by the wavelength. Radio telescopes use multiple dishes and interferometry for increasing resolution, but they need to scan just like single dish telescopes.
[Micro bolometer focal plane arrays](_URL_0_) are becoming used for radio astronomy, but are limited to short wavelengths. Other multi-sensors like the 21cm Multibeam Receiver at Parkes have only 13 sensors which are the equivalent of pixels. | 4fcb12cc-dade-4517-85e3-6590474ceb9b |

ch86du | Why does the WiFi signal get better as soon as you disconnect then connect back to it? | The network may have multiple access points, lots of devices will connect to a certain access point and hang on until they are kicked off.

ch8a5g | Where does money from FTC fines go? How is it used? | Federal fines are paid to the US treasury, where it's used for general government spending. Most agencies don't get to add the money they collect as fines to their budget.
Keep in mind that most settlements report a number that's called a fine in media reports, but may include actual fines paid to the treasury, payments to make those harmed whole (most of the billion dollar settlements with banks went to mortgage bondholders and various foreclosure mitigation programs, for example), or donations to various non-profits who work in the field. | b4dbe9f6-9608-49ae-9524-1d4c569b6477 |
ch8ska | Why does a 1080p Nintendo Switch look great on a 4k TV, but a game in 1080p on a 4k computer monitor look so pixelated and bad? | As people have said, distance, but there is another factor.
4K computer monitors are really only designed to display a 4K signal well. When you send a lower resolution signal, they use very basic techniques to upscale the image and this looks bad.
4K tv's on the other hand are actively designed to be able to display a 4K, 1080P, 720P and even lower resolution signals. This is done through dedicated signal processing chips running advanced upscaling algorithms. (Cheap tv's often save money by using cheap chips which do this poorly.) | 79f6f096-72e8-472d-b07f-d3ce0c9c7172 |
ch9l1h | What is an Order Book and Price Level, and how are they different. | Do you have context for this? Those are fairly common terms that can mean different things based upon the company , industry, or other factors. | 9254f91f-8e6f-44e4-b9c0-c734a263df07 |
ch9na6 | How can a phone send data back to a cell tower antenna if it is miles away? | I think that the cell tower has a big antenna to send, and a big one for receiving.

ch9qm4 | Why doesn’t Wikipedia just run enough ads to keep the site running. | It is inevitable for a business to have to grant some control to those that finance their operations - it becomes the source of your salary, that budget your sitting on that lets you get a raise, or give a raise, that plan for the new office, of for Friday donuts....all depends on money.
If you create a channel of money it's _going to have influence_ and I admire Wikipedia to shutting of one that would be ripe for _problematic_ influence. The needs and wants of a corporate sponsor via ads are different than the users themselves. | c7971d71-58ba-4fd7-b4d3-e2d3c02b1569 |
ch9wt1 | 100AH battery should charge at 10% capacity tops safely....? | Look at the data sheets for the battery because the manufacturer will tell you the data.
Even for general rules is depend on the battery technology you usel Li-ion is quite different from lead-acid.
A 100AH battery charging at 1.1 amp do not take 2 weeks. If it 1.1A all the time it take 90 hours that is a bit less then 4 days. 2 week would bee around 0.3A | 91fe90e8-2f72-4830-8f87-9bde25179cd0 |
ch9z3r | Why an ulcer blister under your lip hurt 100 times more than a regular blister, cut or wound of any sort. | Is the question about "why ulcer at that specific spot hurts more", or about "why does ulcer hurt more than blister"?
Not sure about second one, but as for first - your lip area is a lot more sensitive, because it needs those nerve connections to figure out what you're eating/drinking/touching/etc. Therefore anything hurting there would hurt a lot more than something on, say, your kneecap. | 23d5b4bc-713a-4f45-b08a-add871a6bc9d |
chaj5r | What's the rationale behind extraordinarily long prison sentences? (i.e. 'multiple' life sentences, or 100+ years) | In case evidence turns up to negate one sentence. The person is responsible for all the crimes they committed, not just one. | 2b593c1c-db62-4ccd-964c-3e301fa2af6e |
chalsq | how stock owners pay for stuff | Generally, executives who receive their compensation in terms of stock are already wealthy enough that they have enough liquid funds (i.e. cash) to live quite comfortably. They also will do periodic selling of small amounts of their stock to cash in on particularly good stock performance.
Also, company execs are different than the board of directors/majority shareholders of a company. | 106c6781-a614-4484-8df6-7a41b6339b5c |
chaopn | Are there limitations to who you can represent when you’re a lawyer? | Depends on your jurisdiction (jx). I'll speak from the perspective of a US lawyer.
When US lawyers sit for the bar exam (which varies by state), you take an exam that, if you pass, allows you to practice in almost any type of law. For example, I could do civil litigation today, bankruptcy tomorrow, and criminal defense on Friday - that is fine. There is no specific exam for each individual practice area.
Prosecutors become defense lawyers all the time.
But just because you can jump practice areas does not mean you should - lawyers have an ethical obligation to be competent when they practice law. Therefore, if I wanted to jump practice areas from civil litigation to family law, I would have to study family law more thoroughly before I started to take on clients in that area.
Regarding clients, there are times you cannot represent someone because there is a conflict between the prospective client and a current or former client. A US lawyer owes his clients a duty of loyalty. Sometimes, that conflict can be waived. Sometimes it cannot be waived. It all depends on the facts. | a1da0134-da9a-41d8-aa28-07186e04359c |
chb32x | How exactly does a benzodiazepine and opiate overdose kill you? | But how do these drugs actually kill people? When a person smokes, snorts or injects an opioid, the substance enters the bloodstream, then the brain. There it can act on mu-opioid receptors, says Eric Strain, director of the Center for Substance Abuse Treatment and Research at Johns Hopkins University. “Once the drug binds to those opioid receptors and activates them, it sets off a cascade of psychological and physical actions; it produces euphoric effects, but it also produces respiratory-depressing effects,” Strain says.
As a result, victims of a fatal overdose usually die from respiratory depression—literally choking to death because they cannot get enough oxygen to feed the demands of the brain and other organ systems.

chb4ct | How does HBO afford such big budget shows or the silly expenditures of shows like Last Week Tonight without ad revenue? | Cable. Subscription services make bank, especially with how many people are subscribed to HBO lately. | 44fdc0cd-a028-4265-aebf-13e5e7efef6b |
chbfws | Why can't a sitting president be indicted for a crime? | Because there would be nobody to prosecute him.
It has happened. Lincoln suspended Habeas Corpus, the Supreme court ruled it was unconstitutional because the President lacks that power in the constitution.
Did he go to Jail? No. Did he even go to court? No. All the people that might have arrested him or prosecuted him work in the Justice Department - they work for the President. So there can be no trial.
This works both ways, President Lincoln didn't get a chance to defend himself. If there had been a trial, and Lincoln had won, everybody would have said "They didn't really try to win because they work for him". Right or wrong, this doesn't work.
Recognizing this, the Constitution handles this special condition with a special sort of court-like process = Impeachment. | 7ae764c6-89c5-4c42-9161-b5f87ebe14d6 |
chbost | why have planes stopped getting bigger? | People want to fly directly to their destinations. In the past airlines focused on a "hub and spoke" system where small planes flew between small destinations and major hubs and huge planes could fly between the hubs. The development of long-range, fuel-efficient medium-sized planes enabled more "point-to-point" flights where people can skip the connection in a hub (or at the very least reduce two connections to one). These new planes also allow infrequent flights between distant hubs to be replaced by more frequent (meaning more convenient for passengers) flights. It used to be that if you wanted to fly *really* far you *needed* a 747 or A380, just because those were the only planes that could fly the distance, even if it wasn't the ideal size otherwise. Now you can, for example, replace the 747 on that route with a 787 and just fly more frequently. | 92f1b667-0796-4b96-80b9-44b8bf61eca7 |
chbyfv | How do researchers know when they have found a new species of an animal and not an already discovered species? | multiple factors go into deciding if something is a new species. usually, a color change alone won't be enough, but multiple small changes, or a few big change usually results in a new species. | 073a4c46-53ba-461a-944f-2659eaeedd14 |
chbyli | If 25 degrees Celsius (77°F) is a comfortable ambient temperature, why does it feel so cold when you bath in water of the same temperature? | Water is more effective than air at transferring heat (feeling cold is really just another way to say heat was transferred from you).
Air around you (assuming it's not windy) will heat up close to your body temperature quickly. You are now in your little heat bubble. Air doesn't take much energy to heat up.
& #x200B;
Blow a fan on you while it's 25C, and you now feel colder.
& #x200B;
Get into 25C water, and the water will do the exact same thing the air does, try to match your temperature, except that water takes a huge amount of energy to heat up compared to air. | 75b9a3f5-4be9-460c-9ce3-6366a57ea64e |
chc0yp | Why are sore throats so bad in the morning? | Little bit of speculation, but perhaps because you're dehydrating your throat (your entire body really) plus not washing away any of the bacteria?
You tend to have worse breath in the morning because everything just sits in place overnight. Additionally I know when my mouth is dry (from not having something to drink for awhile), any sort of pain (canker sore, sore throat, etc) tends to be more painful until I drink something. Combine both of those factors into an 8 hour duration or so and you're not gonna have a good time. | ce206266-dff7-4c47-bdb8-53c6e18f5f68 |
chc5xm | Why do you see two shadows of something when there are two lights? | Shadows aren't 0 light, they are *less* light. So when tou have 2 light sources, generally everything is twice as bright, except where the object is in the way, when it is only 1 times as bright. | 17c000d3-2863-4e5e-9480-3ef1978d771f |
chcd0q | What is the hard problem of consciousness and why is it so hotly debated? | The hard problem, per David Chalmers, is that sentient organisms seem to have what are called "phenomenal experiences," or "qualia" - that is, they have internal mental states that are subjectively different for each individual, that those individuals seem to experience just as they experience states based directly on interaction with the outside world, and how and why these states exist and are felt.
Basically, you feel/experience things that cannot be directly linked to your interaction with the world at large when you feel them.
This is a "hard" problem for much the same reason that dualism was/is so confounding for the philosophy of mind - it seems very difficult, perhaps even impossible, to link certain subjective states to well-detailed physical mechanisms.
Take for example the thought experiment of a scientist whose whole life is spent in a black and white room, but whose expertise in the physics, chemistry, neurobiology, etc. of how color is seen is sufficient to say that she "knows what the color red is" in every way *except* experientially - that is, by seeing it herself. We could ask, "does she know what red is?" and by all *purely materialistic* accounts, yes, she does. But, there is something about the *experience of seeing "red"* is not contained in the accounting of *how a human being sees red*, but rather *must be experienced by a human being seeing red*.
The hard problem, then, is effectively why that difference exists, how it it exists, and in more general cases why some of these subjective qualities seem to arise spontaneously, yet still play the "felt" role of states more readily linked to external stimulus. | ac32605a-0a44-48af-b53c-ea339c80edcc |
chcsu1 | Why are birds considered dinosaurs instead of dinosaur descendants/relatives? | In biology, proper groups of animal species (or plants for that matter) are monophyletic. That basically means a group includes and ancestor and all species descended from it. So by definition all dinosaur descendants are dinosaurs...you can't have a descendant of a group not be in the group.
The reason we do this is because it's less arbitrary. Instead of picking a bunch of species we think are similar enough to be in a group, we just put everything descended from a common ancestor in the group.
So birds are dinosaurs because birds are descended from the common ancestor of all dinosaurs. If the dinosaur family tree was an actual tree, birds would be a branch coming off of it, and somewhere pretty high up in the tree too.
Now, that said even outside of proper biological naming, and just in terms of everyday thought, it makes sense to think of birds as being dinosaurs... in fact they are really quite dinosaur-like, and if humanity had developed with a long history of interacting with living birds and living other dinosaurs, I don't think we'd think twice about considering them varieties of the same kind of thing.
To make an analogy, the situation is very much like that of bats and other mammals. Imagine all you had was some living bats and the bones of extinct elephants and rhinos and other large mammals. You might think of bats as being pretty different. But if you compare bats to the broad sweep of mammals in general, they quite clearly fit into the group as a whole. Birds are basically just the bat-equivalent of dinosaurs. | 2d389fcb-89e5-4830-af72-38252545ba2d |
chcu8b | What happens inside our bodys so that, after some time, we can no longer hold weight in the air | It is the ATP-ADP cycle. Your muscles need energy to be able to contract, in the case of the video his shoulder, forearm, and bicep muscles were all contracting to support the weight of the pylons.
& #x200B;
His muscle cells were using ATP along with glucose to contract, which turns the ATP into ADP. But his body only has so much ATP and the rate at which his muscles was turning it into ADP was faster than his body can turn it back. Also, the process of turning ATP into ADP produces hydrogen ions, which in turn creates lactic acid. This is the burning sensation you feel when your muscles are starting to fatigue.
& #x200B;
So in the end there is no "fighting through the pain", eventually your body just runs out of the resources to contract your muscles and your hand just lets go. | 4358f6ed-bae1-45ed-9eea-c553cbc8ab95 |

chdvob | how do milkshake mixer machines stay clean? | The spindle is stainless steel with a small little plastic agitator on the end. Milkshake doesn't tend to stick to the stainless very well and if you give the thing a little spin as you take it out of the milkshake but before it clears the lip of the mixing cup it just flings whatever is still on it into the cup.
What you're missing however is that unless they're removing the spindle and washing it between uses, there is still a little bit of milkshake residue on it and a little that gets splattered on the machine itself. Not a huge health issue since only untouched virgin ingredients touch it, but could be a small (unlikely but serious) issue for anyone with a food allergy like strawberries and you just made a strawberry milkshake. | 937cb43d-75ca-4010-9f95-be926fa71610 |

che2p0 | why do flamingos stand on one leg and do they have a dominant leg? | It is a resting behavior. They spend a good deal of their lives in the water and can sleep in that position. As for dominant leg most creatures have a dominant side, this is more obvious with creatures with hands.
And I am certain that flamingos don't think about it. Having worked with them for years I can tell you that they are some of the dumbest birds on the planet. You catch / trap flamingos by walking in the opposite direction you want them to go and can literally walk them into a cage. | fe9ef8fd-bd74-4948-bb34-96e38d0f235d |

cheuo7 | Why can’t phones and computers charge almost instantly when you plug them in, instead taking 2-3 hours? | Electricity is stored in batteries as chemicals held in two different containers separated by a filter-y thing. Letting electrons flow from one to the other through your phone (for example) is how it discharges.
Forcing the chemical reaction to go backwards is how it recharges, by way of a smaller circuit connected to the charger.
If the reaction goes too fast, it catches fire.
This is annoying, and so coming up with a clever (and cheap) solution is an ongoing challenge in electrochemical engineering. | cb45735b-808b-47d3-be30-c4c124167f23 |
chf11k | why is carbo-loading before an event supposed to give me energy, yet I never have any energy despite eating mostly carbs | A lot of your reasoning here is an oversimplification of complex nutritional concepts.
Let's start with how your body processes carbs. A carbohydrate is a chain of sugar molecules. Your body breaks down the chain into individual sugar molecules, which then go into your blood, which feeds your cells, and gives you energy.
Your body always needs energy, so you need sugar in your blood at all times, but too much sugar can damage your cells. Because of this, your body has a way of storing sugar when the levels get too high, and releasing stored sugar when it gets too low. When blood sugar gets too high, your body releases the hormone insulin. Insulin takes the sugar in your blood and stores it as glycogen molecules. Glycogen is basically just long chains of sugar molecules that are stored in your muscles and liver. When blood sugar gets low, your body releases the hormone glucagon, which breaks apart the glycogen molecules into sugar again, which raises your blood sugar levels.
Carbo-loading is done by althetes in endurance sports to top-up their glycogen levels to the maximum. Since the althete will need continuous, high-levels of energy for a long period of time, this is very important to keep their blood sugar up, and their energy levels up.
Now on to you and your low energy. What kinds of carbs you eat is very important. Do you eat complex carbs, or simple carbs? "Simple carbs" are short chains of sugar molecules (found in refined sugar, soda pop, white bread). "Complex carbs" are long chains of sugar molecules (found in vegetables and whole grains). Your body is able to break down simple carbs much faster than complex carbs, which quickly raises your blood sugar level. Your body triggers the release of insulin in response to deal with the high sugar levels, which causes your blood sugar levels to quickly drop. Therefore you feel energetic for a short period of time, followed by a sudden decrease in energy. This is probably the cause of your low-energy levels. Complex carbs take longer to digest, so they release sugar into your blood consistently and slowly, thus avoiding high amounts of insulin from being released. The result is that your energy levels are much more stable for a long period of time.
In summary, eat your fruits and vegetables, and avoid processed foods! | 9a4cadbb-a174-4837-bae6-857eb926e02d |
chf2zm | what is the butterfly effect? | It refers to "one small change can have dire and catastrophic consequences"
"kill one butterfly in the past, ww3 in the future"
Can explain a crazy chain of events that COULD happen if the right sequence is triggered. A popular video game that utilizes this trope is the horror game "until dawn", where every action you take has the possibility to have disastrous effects
Example: say you traveled into the past. Like, a billion or so years. You saw an almost lizard like animal crawling about and you accidentally step on it, killing it instantly. You think nothing of it and go about your day, eventually coming back to the future. What you find though, is that lizards no longer exist because when you traveled into the ancient past, you accidentally killed the original female organism that would eventually become a modern day lizard. So now lizards don't exist because of one small event that took place. | a501ce1e-ece9-4035-9684-e2efe327c785 |
chf95o | If you're stranded in the middle of the ocean and start to feel dehydrated, why is just drinking the seawater around you bad? Why will it not hydrate you? | Osmosis. Salt water has more salt in than the cells in your body and your blood. So instead if drinking salt water and the water being absorbed, it actually gets drawn out of cells towards the saltier water. You end up peeing out more than you drink because the kidneys can't concentrate the urine more than the salt water, instead water is drawn out into the urine so you lose water. | 49f4f164-9511-433b-9660-d021f8443c90 |
chfi0c | What is a schizoaffectice personality disorder? How does it affect a relationship? Do you have any experiences with being in a relationship with someone who has a sad? | In terms of mental health, SAD is an acronym typically reserved for Seasonal Afflictive Disorder, which is something different. Schizoaffective disorder is basically like schizophrenia and bipolar disorder had an angsty child together. Its manageable, but it never goes away. I would imagine that it would make for a strenuous at best relationship for both parties. My cousin was diagnosed with schizophrenia, went off meds, and is currently and probably permanently hospitalized. My mother had bipolar disorder. Just imagining them together in one person, even when its not at the worst, would be hard to cope with. Any kind of depressive disorder makes maintaining a relationship painful to both parties, and far too few people understand that depressive disorders isn't just someone feels sad, and they have no control over it so they can't just think happy thoughts and make it all rainbows and sunshine. Just being alive is sometimes a struggle. That has a way of wearing down anyone, and yes I mean anyone even if they genuinely and truly love you from the bottom of their heart. Counseling, appropriate medication, and as odd as it sounds a good hobby are all helpful for coping, but it's going to be hard. | d8e5920f-6fd0-410e-aa12-6c465cfbafe5 |
chfp1c | Why was it custom for men and children to wear suits, ties and other smart clothing during the 1900's? | That was just the style back then. You always had to look your best when going out in public.

chfv3r | How do charitable promotions work a large stores? | Yep you are right. Lets think of an item. This item costs the store 8$ then the store sells it for 11$. So the difference there is 3$. Of the 3$ let's say 2$ goes towards employee salaries and business expenses. Then 1$ is the profit. If the business is saying they give 10% of profit sold to charity it means 0.10$.

chfv7h | How exactly is a calorie "burned"? | From a chemistry standpoint, they mean it quite literally.
A calorie is a unit of energy.
This energy is stored in the chemical bonds of a molecule, almost always in a molecule of carbon, oxygen, and hydrogen.
When you eat and digest it the food, it turns into one of those molecules your body can burn for energy.
When you burn the calorie, you add oxygen, and the carbon-hydrogen-oxygen atom turns into carbon dioxide and water + energy form the bonds freed.
This is chemically identical to regular burning.
You then exhale the carbon dioxide.
The CO2 you are exhaling weighs more than the O2 you are inhaling.
That's where your weight goes. | 2bcfe0b2-c6c8-44be-bd86-f909ca8d5157 |
chg0zj | Why aren’t you supposed to cut the tags off your mattress? What happens if you do? | That's just for the retailer. It has important fire safety notices for the consumer.

chgnm5 | Why does WiFi in a house or office still suck in an age where we can have a drone transmit a WiFi HD video signal from a mile away? | I wouldn't say WiFi really sucks.
It all depends on the setup you have: if you have a sufficient number of access points (antennas), or if the ones you have are strong enough. Your house plays a big role in this as well, thicker walls means a bigger loss in signal strength. There's two frequencies used right for WiFi, 2.4 GHz (slow but penetrates walls better) and 5 GHz (fast but bad wall penetration).
All this to say if you have a decent router (not the one your ISP sends you) and you place it at the right spot, you'll be just fine. Maybe add a few repeaters or install a mesh network if you have a bigger house.
For drones, it's simply because usually they're transmitting in open space (outside) and have only one connexion. It's using a different type of transmission which is more suitable for distances bigger than the size of a home. | 4f566482-8c23-4637-b6b6-9e74f438f292 |
chgr73 | How does going through an emotional episode (ex. heavy crying) physically exhaust the body, when you’ve likely stayed mostly stationary throughout it? | While your body was stationary, your muscles inside your body were not. Your heart was pumping faster, andrenaline was being injected into your muscles, you were tense, etc.
Andrenaline itself is well known for leaving the muscles feeling tired once it leaves. | a3312e0e-d377-4c33-8911-826433f636ff |
chgt3s | How do micro organisms survive in the stomach? | There a many many many different types of bacteria. A lot like environments that have neutral acidity, normal temperatures, and low levels of salt. However then there are some types of bacteria (called extremophiles!) that like high temperatures or high salt levels or acidic or basic environments. The acidophiles (extremophiles that specifically like acids) grow best or at the very least tolerate acidic environments. | 63b6ddc9-3965-47f5-a486-2c01142712fc |
chh1c7 | Why is fiberglass not considered as dangerous as asbestos? | Asbestos fibers are small - really, really small. They can easily get past the body's defenses to particulates (mucus membranes, fine nasal hair, etc.) and settle deep in the lungs, where they cannot be removed by any biological process. These fibers persist and irritate the lungs, leading in many cases to a particularly nasty form of cancer (mesothelioma). Asbestos is also easily friable, meaning small disturbances to installed asbestos produce huge numbers of tiny airborne fibers. The combination of friability, easy passage to the deep parts of the lungs, and carcinogenic impacts makes asbestos particularly hazardous to human health.
Fiberglass also produces particulate matter, but it's much, much larger (typically) than asbestos fibers, so your body stops most of it from entering the lungs. While it's an irritant, it is not carcinogenic. So, it's bad, but not nearly as bad as asbestos.
Silica, especially in foundry and blasting work, leads to silicosis, which is also bad, but not (typically) as bad as asbestosis and mesothelioma. Coal dust leads to black lung - also bad, but not in the same league as asbestos. | 1676c39b-a0ad-4607-bddc-bd2174d1d436 |
chh43r | Why do sad situations make it feel like our hearts are actually hurting, when it's just an emotion. | When faced with stressful situations (includes situations that make us sad, like a break-up, or a death of a loved one), the body produces fight-or-flight hormones. These have an effect on the blood vessels on the heart, raising blood pressure and increasing heart rate, which all increases the stress on the heart. Sometimes, these can cause the blood vessels to spasm, periodically cutting off blood supply to a particular part of the heart. This causes the heart pain you feel.
When the heart is faced with this situation repeatedly over a long period of time, the heart becomes weaker and is less able to pump enough blood to supply the body. This condition is known as Takatsubo’s cardiomyopathy or more widely known as broken heart syndrome. | ce7c869e-6073-48aa-81d3-a9a3ca9089c5 |
chh4lc | What is happening in your stomach when you feel like it's "dropping" on a roller coaster? | The force of the coaster as it accelerates and decelerates very rapidly applies force to your internal organs, but they are held in place by some internal membranes that have some elasticity. Your stomach resembles an expandable bag so it tends to have more movement and elasticity. So the effects of the rapid speed changes have a more pronounced effect on the parts of the stomach that aren’t really securely attached to anything and that is what you feel. | 863cbcd9-df6d-4055-a404-32b65c48343a |
chhfvo | Why shouldn't I mix old and new batteries or batteries of different types (disposables with rechargeables)? | Different batteries have different voltages. And you don't want to try recharging a non-rechargeable cell.
Rechargable batteries generally have a voltage of 1.2 volts, compared to heavy duty or alkaline cells with 1.5. If you were to put a rechargable battery in parralell with an alkaline cell, the alkaline cell would discharge through the rechargable one, overcharging, overheating it and probably damaging it.
Batteries also have different capacities - so putting a cheap heavy duty in series with a fresh alkaline or rechargeable cell, or a partialy discharged cell with a fresh one, when the low capacity cell discharges the cells that still had capacity would force charge through the dead cell, charging it backwards. This will cause the discharged cell to leak. | b40930cc-e200-420c-9c58-ec1d138cbda8 |
chhg18 | Why is arachnophobia not only such a common thing in humans, but often times severe enough that even something as far removed as a picture of a nonexistent fictional spider is enough to cause discomfort and anxiety? | Probably because many spiders are venemous, and so, like snakes, people evolved to fear them.
There aren't very many creatures common throughout the world which can poison us, spiders and snakes are the only ones which come to mind really. | 3e2e58fa-6cea-4782-a0d2-b7a7fd7a854c |
chhg5z | In the Rick and Morty Universe why are all of the iterations from all of the dementions the same age? | Because these aren't all the Ricks and Mortys these are all of them on the central finite curve. What rules govern which universes are and are not included aren't mentioned but it can be assumed there are some because it is finite, not infinite. Also, we don't know they all are the the same age, maybe some of them are thousands of years old but halted their aging, maybe Morty at this age is perfect for Rick's work so he doesn't let him get any older. Thats a stretch of course but you could make a bunch of similar points like that. It's all about that finite curve. | 675fe92e-5361-47cb-a4fa-6aa431fa9bad |
chhoys | what is the difference between capital gains and dividends? | Capital gains are when an investor sells a stock for a profit.
Dividends are typically when the corporation has made so much money that they would like to reward the investors. So the company gives them cash every three months or so. | e9217f76-bd77-47f2-b7d4-26a7fe21f139 |
chhq7q | What causes that brain fog kinda feeling ? | insulin can do that. Your body releases insulin (technically a hormone) to help process carbs in the food you eat. That can be one reason why people feel sleepy after they eat a big pile of pasta, for example. If a diabetic patient gets too much insulin in a post-meal injection, it can “fog” them so much that it could be fatal. If you’re asking because you struggle with brain fog, one thing you might try is eating more but smaller meals to minimize the amount of insulin your body secretes at any given time when you eat. Also not eating a bazillion carbs in any one sitting.
This is just one of many, many causes of brain fog. | f87096d3-5ecd-43d1-ae6c-d602fad86c57 |
chhvfr | Why do recycling centers not accept all cans/ bottles? | Pretty much all your trash has to be washed and clean or it "won't go through the recycling machines."

chi09x | When walking with a glass of water, why is it more likely to spill when you watch the glass opposed to looking straight ahead? | Scientists have done studies on this, surprisingly. And as it turns out the opposite is often true, but with some particulars on the details. The study done was involving coffee, and scientists found that the average human gait oscillates the coffee in an average mug at exactly the right (or wrong, depending on how you look at it) cadence to cause a spill in approximately 3 steps. The thing that they found most people do wrong is try to get from point 'A' to point 'B' quickly which causes excess oscillation and speeds up the point at which the coffee will spill. Additionally, You should focus on your cup and not your feet. Doing so slows your pace, dampens the oscillation frequency and will help prevent spillage.
Edit: I'm adding in this portion because I forgot that this was ELI5 and not AskReddit.
Liquid splashes back and forth with each step, when you walk quickly it splashes more and causes it to build momentum back and forth like a skateboarder on a half pipe. Focusing on the glass has been shown to cause you to slow down so that the momentum doesn't build up to much, and your coffee doesnt spill. | f3086776-cda8-41c0-8a0d-4347c1938e20 |
chiaki | How do wild animals know what is safe to eat and what is not? | Smell and taste warn both people and animals what is poisonous and what is not. There are some things which are hard to identify as poisonous because they have no telltale smell, taste, or appearance, but most things warn off people and animals.
The aversion to the smell and taste of poisonous objects is driven by evolution, since only those who found poisonous objects awful in taste or smell would survive to pass on their genetic traits.
The natural instinct to detect poisons in humans has decreased precisely because humans learned to communicate and pass down their knowledge. While decreased, vestiges of this instinct is still obvious. The smell and taste of rotten food is awful to us. Our taste buds developing the ability to taste bitterness is also a consequence of this evolution. | a539e5ef-6a20-433f-be62-563cc9ad1ae9 |
chibyp | How do both eyes move in the exact same way? And why does it cause strain when they don’t (e.g crossing your eyes for too long) | When the nerve going to one eye is stimulated, somewhere along the way that same nerve stimulates the nerve of the opposite eye. So essentially both nerves for each eye are stimulated at the same time when your brain decides to look a certain way. | a8a7d79f-5612-47c9-b23f-95db25dd1130 |
chig1n | Why can't a sitting president be indicted for crimes while in office? Is this a set rule or just tradition? | The question is: who does the indicting? The President has plenary power over the executive branch. He would be the boss of anyone who would be tasked with indicting him for a crime. It wouldn't make any sense.
Who is the President *not* the boss of? Congress. That's why the clear course of action to control the head of the Executive branch is impeachment, not having a subservient member of the Executive prosecute his own boss.
(The President is not the boss of the Supreme Court either, but the Supreme Court does not have the power to set its own course of action; only Congress can do that) | ce8c7d9b-3437-409f-9116-16724d22d1c2 |
chigy1 | What are the numbers on your glasses RX, and how do they corelate to your visual accuity? | The numbers indicate Diopters of correction for your prescription lenses. A Diopter (D) indicates that the focal length of the lens is at 1/D meters. The higher the Diopter value, the thicker the lens will be to bend light better.
If you are nearsighted, the Diopter values of your lenses should be negative to correct for your nearsightedness (focused too closely). For simplicity, let's say your prescription is -3.0 D to cancel out the 3.0 D of your eye. 3.0 D means your nearsightedness puts things at 1/3 meters in focus (about a foot) without glasses.
Calculating equivalent visual acuity is a bit trickier and involves ratios. The thing with optical focus is that the ratio of the distance an object is to the focus determines how blurry it is. With your eyes focused at 1/3 meters, something at 6 meter (20 ft, the distance of the eye chart) gives you a ratio of 6 / (1/3) = 6 x 3 = 18. For someone focused at 20 feet, the equivalent blurriness is the ratio multiplied by 20: 20 x 18 = ~400 ft, indicating 20/400 vision. This holds true for nearsightedness but farsightedness is more complicated. | 37f551c4-ca28-40e7-9fc4-c57bd3d28dd4 |
chirps | What’s the difference between 4WD and AWD? | Typically 4wd has locking differentials that send even power to all four wheels. AWD sends power to specific wheels typically with front or rear bias depending on car, and then all or none of the power to appropriate wheels based on available traction when conditions require it. | d854ae7c-4e6a-4ce9-92ab-a6bdbae71001 |
chiybb | Why does seeing other people vomit make us want to vomit? | The evolutionary advantage of "contagious vomit" is that in a group of people if someone got sick from something, it was likely others would to. So...first person eats something poisonous or that has gone bad and makes you ill, then others wold get it out of their system _early_, rather than wait until genuine symptoms produced their own vomit.
It's _likely_ that this reaction was advantageous and increased likelihood of surviving as a trait - it would certainly prevent certain kinds of toxic materials from taking out an entire village if getting it out of your stomach early increased likelihood of survival. | 6403daba-d10d-4611-b4e2-8b7bf6074f8a |
chjcca | What does it mean when politicians say they want to “break up big tech companies” and why do they want to? | Breaking up a tech company is when a government forces a company to devide what it does into separate business.
So for eg, if you have a tech company that has 80% of search share, 80% of mobile share, 80% of online video share, then you may be concerned that the power they have over so many integrated spaces, will harm competition. And decide that they should be broken up.
You would then force them to have _URL_1_, mobile os and _URL_0_ be separate businesses. That way the power they hold in each can't help control other businesses.

For example, in the UK we’d consider 30 degrees Celsius to be very hot, but I know that’s not the case elsewhere. | In the UK, we don't have hot weather infrastructure. Our houses are designed to keep heat in. The only place we have air conditioning is in cars. Plus the humidity is likely to be higher in the UK.
Countries that experience heat regularly have different building structures, air conditioning in some countries. Sometimes change in societal habits, such as not working at the hottest part of the day. | bc39ef81-234a-480a-a950-a712746bdcad |

chk133 | What is the basic difference between a "syndrome" and a "disease"? For example why is it called Tourette's Syndrome or Parkinson's Disease and not vice versa? Is there a set criterion or threshold that needs to be met for such classification or to go from one classification to another? | Generally speaking, a syndrome is a collection of symptoms that are related to each other through some common cause, and a disease is a single cause of some illness, but there's a huge area of overlap in using the two terms. For example, AIDS is syndrome (in fact that's what the S in AIDS stands for) because it's a collection of many possible symptoms and opportunistic infections caused by the HIV virus. Measles on the other hand, is a disease, because it's one single virus that does specific things and has specific symptoms. | 0d3a55ae-dd77-493b-93d5-6bd1255a469b |
chk1i4 | Why do pets get so hungry when they have much higher quality food than ever before in history, a regular supply, and they don't need to expend any energy to get it? | Because the body of animals has evolved over millions of years for survival in the wild. And animals have only been domesticated within the last 30,000 years.
So even though it’s higher quality food, and is constantly available, and they don’t need to hunt, and they don’t need to survive a harsh winter outside - their body’s behave as if they do.
Replace pets with humans and due largely to the same mechanism you have probably the strongest explanation for the current obesity crisis in the western world.
Sadly this is not true of my dog who needs to be coaxed to eat every day - she would NOT do well in the wild - So think yourselves lucky it’s not the opposite any time you resent the glorious over eating of your pets haha. | 5650b07b-2b61-4ba9-9600-09ec53602c37 |
chk8by | How do anime companies win profit? | I believe Japan still relies heavily on physical sales for their revenue. So the cleanest way to support a Japanese anime is, unfortunately, to actually purchase the DVDs. There may be officially licensed sites but they could be hard to find or access. Generally if the site you are going to is "mainstream" like Viki, Cartoon Network, Netflix etc, they pay a royalty or license fee to the anime production company for the right to stream their anime.
Any site that appears unlicensed probably pays the production company nothing - essentially it is pirated content. | 173982ec-adeb-41f5-86dc-d9102432a77c |
chkaep | how does helium change your voice? | When you speak normally your vocal cords vibrate at a certain speed or frequency this is usually the same when you are breathing air.
Helium is a much lighter gas than air, which is why balloons filled with it float so well. When it passes over your vocal cords they vibrate faster which makes the voice sound squeaky because of the frequency of the movement of the vocal cords.
Yes it will make a little girl or boy sound squeakier but as children's voices are naturally more high pitched, the effect will be less pronounced so you might not notice it as much.
*Putting my fun police hat on now; it can be very dangerous to breathe in helium and other gases, so whilst funny it's not recommended, particularly for children, as they might suffocate and no one wants that.*

chl1rg | Why does mankind not build the same way as they would in space? | We could, and there are a few examples of where we have, but the main reason is the same one driving pretty much all decisions that are made - cost. It is much, much, much cheaper to build traditional style buildings and just pump resources into and through them and out the other side than it is to build the kinds of buildings you are talking about. At the moment, there is just no real incentive to, although there is plenty of reason. Ultimately, we’ve had the tech to address sustainability issues for decades, but the political and economic will hasn’t been there to actually develop and implement it.

chl261 | How do birds go forward when flying if their wing movement makes it look like they would only go upwards? | The flapping motion itself is generally used to build or maintain height. However, with the angle and shape of a birds wings, a bird can adjust its tilt slightly while flapping or gliding to build forward momentum. The forward momentum builds as the bird tilts forward, and will accumulate as the bird flies through the air. Birds can adjust the angle of their wings to flap with a combination of upwards and forward momentum. | 58bf865b-7b70-4c22-af93-8c67af629cb9 |

Sometimes this is said that because words are orthographically the same (spelt the same, like sewer (one who sews) and sewer (long pipe for poo)) but said differently (sow-er vs sue-er). | 01b1156b-951c-4319-8009-ed6cf52603af |
chlrq8 | With the millions (or billions) of barcodes in the world and more being added daily, how are they all unique? | Barcodes are actually just a font what represent the numbers that are normally printed just below it. The most common type of barcode in North America is the UPC (Universal Product Code) that is owned and managed by GS1. GS1 officially licenses barcodes for products for sale, using a system where the first N numbers of the code represent the manufacturer of the product, and the rest represent the product from the manufacturer.
By sticking to this system, and making sure that their barcodes use the correct manufacturer number, they can know they wont be overlapping with another manufacturer.
Manufacturers can also pay more to get a shorter manufacturer code, so that they can have more digits left over to have more products. | 2855841c-2edf-4200-aeb7-fb3962fe7437 |
chlz9m | Why does using an ad blocker cause the youtuber not to earn ad revenue? How does youtube know that ads are being blocked? | I'm not sure which method YouTube uses. But one common method of measuring ad displays is looking at how often an ad image is displayed.
When you see an ad on a website, it means the image for that ad has been downloaded to your computer to display it in your browser. This download can be tracked on the server where the ad has been hosted.
When you block ads, you prevent the displaying and thus downloading of the ad image. Which means it never gets counted as a displayed ad. | 43e8cf5b-d12c-4f66-862c-dc3349ebf83d |
chm2s6 | Meteorologically speaking, why is it suddenly so extremely warm in western europe? | It really should be called **runaway global warming**, to tell the truth. But to answer your question -
Approx 20 years ago the weather was like a fair dice (1.2.3.4.5.6) So there was always an equal chance of any temperature, rainfall, humidity, snowfall etc etc ; and approx 1 in 3 chance of an extreme weather event
But Climatologists agree that the dice has become loaded within these 20 years (1.1.3.4.6.6) . The chances of throwing extreme events has doubled (approx) so in any calendar year you should expect at least one fucked up weather event in your location
This is difficult for climate deniers to understand but global warming can cause instability which can cause extreme cold (eg USA/Canada last winter) | b2b2eea9-90bf-4f9a-bfb0-1123315d5372 |
chm3c5 | Why when penguins walk, they walk in a row? | Same reason any other animal including humans tend to walk in a row when going across difficult or dangerous terrain: they're following a path.
The path is often less obvious than the ones followed by, say, elephants in a jungle, but it's there and the penguins know* where it is and that following it is easier than going any other way.

chm4ok | Why do horses have horseshoes on there feet? Do they need them? | Horses in their native environment generally spent a lot of time walking on harder, more arid terrain, which over time would harden and shape the hoof into form, sort of like a callous. Nowadays, however, horses tend not to move around nearly as much per day and do so in wetter environments and softer terrain. As a result, their hooves tend to remain softer and more prone to injury. Horseshoes came about as a means to protect their hooves in these conditions. | aec1a076-1696-42cd-a0b1-ee2817217dff |
chmd6d | Were little old people always little or do they shrink as they age? | Most people do shrink as they get older and their bodies degenerate.

chmeu9 | How can you tell the odometer reading from a totaled newer car with only a digital odometer and no dial odometer? | If you're not able to power up the ECM to get it with a reader then I believe the insurance companies ballpark it off your driving and service history | b2fc8a3c-efa2-4cac-a590-27780b98c04a |
chmnng | How does the sound quality of a headphone/earphone vary? | The same components it not identical comments. A sports car and every day car can have the same components but they are not identical.
If I am not mistaken it is the membrane that is the most important part. You need one that is symmetrical and vibrate the same in all frequency so the manufacturing tolerances is low in both the material and how it it is mounted. It need to be mounted in some frame that do not vibrate the incorrect way.
The magnets need to be identical in both ear and the coil need to be wrapped the correct way. Those part is likely simple to manufacture then the membrane and the other part of headphone. So the tolerances for the cheep and the expensive part is different.
Small difference in the plastic part can have a effect on the sound and there is wear on the mould when they are used. So you need mould that is manufactured with high accuracy and it changed relative often and that cost money.
A good comparison is LEGO and other brick that look the same. If you have used both they look identical but when you put then together LEGO will stick together all the time but the copies often used worse mould more times so the plastic part might be a few thousands of a millimeter off and then they do not stick together.
Lego used mould that is made with higher accuracy and used a comparable short time. It make the product more expensive but all part work and stick together. I have had the misfortune to glue a robot of LEGO like brand together because the 5 years old that had got it could not play with it because it just fell apart. The part look identical but the are not. | 7b853377-f0f6-4876-ba7c-c8b0381d369a |
chmogs | what are the purpose of horse shoes? | The hooves of a horse are made of the same material as fingernails. It wears down easily on roads with tightly packed dirt and on stone. Tamed horses which are ridden or used as beasts of burden also tend to move around a good deal more than those in the wild, so the wear on their hooves is a serious problem even if they only travel on naturally occurring materials. Horseshoe helps prevent the wearing down of the hoof and extends the productive lifespan of the horse. | 3286c2bd-51b7-454a-9f23-c74a4ed4b1ab |
chmtkr | Why is it that when we take a picture of the sun or moon with our phones it never really looks like we see it with our naked eye. | Dynamic range. Your eye can resolve a candle a mile away at night, or the sun shining on white walls at noon, basically at the same time.
Phone cameras are more limited, and tend to adjust for the brightest object in the field of view. That tends to darken everything else relative to your eyesight. | cabc1931-e9ec-4275-8392-033233661b74 |
chn2m5 | Why do people get sick? | "Sick" is your body taking drastic measures to fight off germs. Fevers, for example, are cause by your immune system intentionally raising your body temperature, slowing down germ growth so your body can eliminate them. Coughing, sneezing, vomiting, etc, is your body's way of trying to expel stuff from your body before they cause more harm. | e4a84a9d-4aef-47c9-a04d-2a2dd2e45091 |
chni7d | Why does the "well-regulated militia" part of the 2nd Amendment of the US constitution always seem to be ignored? | Well-regulated is the point of contention in the US Constitution.
The debate is whether it means “well trained and proficient” or “controlled by legislation”.
The argument for “well trained and proficient” stems from English language references from the 1700s. Historically, a well-regulated military was one that was trained and disciplined. Hence why the standing Continental and British armies were called “Regulars”. The idea that a militia be “well-regulated” (ie. well trained/proficient) is so they may be called upon in times of need. The reasoning behind this was that with increased gun ownership, the owners would be proficient enough to use firearms in a militia with little to no extra training.
The argument for “legislatively controlled” is a more modern take on “well-regulated” that uses modern English terminology to explain the plain language of the Amendment. Some scholars argue that individual state security was a reason for the Amendment in the first place and that militias no longer have a place in their the US. Regulation in modern English is more in line with legislative operations, not with the regularization (standardization) of military forces, regular and non-regular.
So, to answer your question: “Well-Regulated Militia” isn’t ignored. It’s a point of contention between originalists and revisionists. | f6f76401-fb48-49d1-b7e2-9d67058fcf6a |
chnm51 | If every cell in your body is replaced every 7 years, then how do tattoos last a lifetime? | Every cell in your body isn't replaced every 7 years. That's an incredibly prevalent and popular myth. A great amount of your body (e.g., muscles, heart, lung, nerves) never regenerate and the cells you have at around puberty are all the cells you'll ever have.
I guess I'll have to answer your question by posing another question: why would tattoos go away? It's permant ink just sitting there in your tissue. Nothing is taking it out. Skin does replace itself, but why would that cause tattoos to go away? Where would the ink go? | b5a30b0c-4f39-4eb2-9ebf-caca6b67f0c9 |
chny7p | Why do some wounds heal and leave no trace but others can scar and leave a permanent mark? | All wounds leave scars to some degree, though they may not always be visible. In short, small scrapes and cuts with a smaller area of trauma will usually not leave a noticable scar. Bigger and deeper wounds scar more due to the healing process and our bodies trying to heal them as quickly as possible.
To go into more detail, scars are made from collagen (which our body makes many different types of). When a scar is first forming, fibroblasts migrate from nearby undamaged tissue and lay down collagen. Our body can quickly produce this type of collagen when trying to speed up the healing process. The collagen usually ends up being aligned in one direction (different than the usual "basket-weave" texture of our skin), which is the main cause of visible scars, as the resulting tissue is smoother and looks different. As the healing process continues, this quick-forming collagen is degraded and replaced by a slow-growing collagen which is much stronger and protects the wound better. This collagen is one of the reasons our scars fade over time.
The reason smaller wounds tend to scar less (and why doctors stitch to keep wounds as small as possible) is because the smaller the wound, the less collagen and healing time is necessary. Stitches help pull the wound edges closer together and speed up healing. But we don't usually get stitches unless the wound is big and/or deep. Stitches only tend to be used when doctors think that the underlying structures are at risk of damage, or that healing will take so long that there would be risk of infection. This is why the wound may be cleaned first before stitching.
I hope this was clear and answered your question!

chnzhm | How important is sleep for muscle gains? | Extremely. Exercises causes “muscle gains” by damaging the muscle fibers (technically the microscopic action and myosin filaments which are what cause muscle contraction). The main period of time that that damage is fixed is during sleep. No sleep, no large scale repairs. When the damage is fixed, either more fibers are made (hyperplasia) or the fibers get bigger because more actin and myosin chains are made (hypertrophy).
It’s kind of like how a large scale highway repairs and roadwork is typically done at night, when there are less people on the road. The workers are more productive and can make more progress at night, with less traffic. During the day, with thousands of people driving by, the workers have significantly reduced productivity. Muscle repair is similar. You have reduced energy demands at night, which means more energy can go to fixing muscles. You also aren’t really using the muscles during sleep which allows for repair to occur. Muscles will start getting repaired during the day, just not nearly at the level as during sleep. (Also sleep is just good for you in general. No sleep will literally kill you, either acutely or through an increased risk in heart failure, metabolic disorders, stroke, and motor vehicle accidents). | 7b08b730-77cc-4ffa-a427-9fc35b6986b7 |
cho00q | The UK is currently in middle of a huge heatwave which is hitting Europe. This heat is causing trains to be cancelled or run slowly due to fears of tracks ‘buckling’ from heat. Why is it that in mainland Europe where countries have high heat more often that trains are ok there? | I'm from Belgium. I've just to taken the train to make my daily connection Brussels-Antwerp. On a normal day, it's 45 min. Today it took me 1h45 min., because of trains cancelled or running slowly.
So don't worry mate! It's the same in mainland Europe!
