[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why can animals drink dirty water where as humans cannot?" ]
Humans can drink dirty water. Until the last century dirty water was just about the only kind of water anyone could get. People often died from waterborne pathogens and pretty much everyone had parasites, but the same is true of most wild animals.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "What is the point to things like Origami Owl, Scentsy, Paparazzi Jewelry, etc. that use a consultant to sell?" ]
It helps spread the word about the product without costly marketing fees. Consultants earn an income and sell the stuff to their friends and acquaintances. It's a good process for the company because they only have to pay a commission rather than employ people full-time and have to provide benefits.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How do people who colorize photos know what color to make things?" ]
Depends on the source photo. For example old photos with advertisement or firetrucks or uniforms, it can be deduced from modern colors what their original color was. Otherwise the colors are just chosen arbitrarily so that they seem realistic and suitable for the given time the photo was taken.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Are humans still being naturally selected?" ]
Yes! A concrete example of this: There are large areas of Africa, Southern Europe and surrounds where the population has quite a high proportion of people that suffer from sickle cell anemia. Sickle cell anemia sufferers can't transport oxygen around their body as well as people with normal blood cells. This is obviously a disadvantage. So why are there lots of people in these areas with sickle cell anemia? These areas have a lot of mosquitoes, which pass on malaria. However, sufferers of sickle cell anemia have a natural immunity to malaria. The people with sickle cell anemia tend to survive longer in these areas, and pass on their genes. This is natural selection in process. It is better to have sickle cell anemia than malaria!

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "What is credit and why is it necessary?" ]
* I'd say yes but the better answer is it can be, because people with bad credit will be able to get (very high interest) options that people with no credit might not be able to. * You build credit by getting credit. You have to get a first card from someone, usually a $250 or $500 limit. If you, for whatever reason, absolutely can't get one, you can get a secured credit card where you have to put down a deposit upfront and that will build your credit. * Having a credit card will cause you to have a credit score to begin with, and paying it on time and keeping the balance reasonable will cause it to go up, which will allow you to have access to more credit. Credit's necessary if you ever want to finance a house or car purchase. If you pay for things with cash, truth is, you can go through your whole life without it. But I don't mind the idea of other people letting me use their money as long as it's cheap enough. /r/personalfinance can go into far more extreme detail but it's closer to ELI45.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "difference between a lunar eclipse and a new moon." ]

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "What is a Grand Duchess/Duke, who is eligible to become one, and what do they do?" ]
A Grand Duke, is usually the ruling monarch of a minor nation. The title is less of senior Duke and more of a junior King. Small provinces changed hands frequently in Europe, often without changing nobility, and often found themselves as independent states. That noble would find themselves as the head of state, more than a mere Duke, but did not want to presume themselves to be the equals of the true European powers. In addition, the nobles under a Grand Duke often enjoyed greater freedom than they would under a King, and would use the title to limit their monarch's power. To become a Grand Duke, you start of as a Duke, wait for your country to go to war, then have your province made into an independent state.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Does bank account with all money which my country hold exist ?" ]
I once heard a guy on the radio who told that he performed transactions on the Dutch government national bank account, account number "1" at The Netherlands Bank. For instance, when the Netherlands needs to pay fees to the European Union, it is done from this bank account. I'm not sure if this account "holds all the country's money", but these kind of national bank accounts exist.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Since cats and dogs have multiple offspring at once, are they considered genetic twins? If not, can dogs and/or cats have twins?" ]
yes and or no. So twins are born at the same time and can be identical or fraternal. fraternal twins are genetically siblings, while identical twins have identical DNA. Fraternal twins happen when two separate eggs are released and fertilized very close in time to each other so they both attach to the womb and are born at the same time. This often happens for dogs and cats since their bodies almost always release multiple eggs at the same time. Identical twins happen when one fertilized eggs splits early in development into two eggs and they each grow seperately into a fetus (baby). This can happen with one egg in the womb in the presence of others. So it is possible for a dog or cat to release say 2 eggs both to be fertilized, one of those eggs to split into two, and.....give birth to one fraternal triplet and a pair of identical twins. in this case the first puppy is genetically a sibling to it's two siblings, and the twin puppies are identical genetically to each other.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why do trips seem to last longer while going than while coming back?" ]
I feel like it's more because of the anticipation/ possible fear of actually reaching your destination. After you arrive and do what you're there to do I'd say the journey back to where you came from is spent more thinking about what you did. Example: An 8 year old on its way to Disneyland (no sponsorship intended) all excited and hyper thinking about all the things it'd do so the anticipation is killer. But I'm not a psychologist 🤷‍♂️
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How are scholarships with ethnicity requirements legal?" ]
It's called affirmative action or positive discrimination. Basically discriminating in favour of certain disadvantaged groups that have possibly suffered as a result of discrimination.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How does this even work from a structural engineering standpoint?" ]
I can't comment on that specific structure since it could be a cheat such as you described using internal support of some type. However, such a structure is possible in theory. It is a complex looking version of an arch. Notice how the bricks are higher in the middle? Those bricks rest on the ones below them just like a regular arch. The twist makes it seem more impressive but the idea is the same. The hardest part to keep from falling is the almost straight section at the bottom near the central pillar but if you look you will see that the twist means that the bricks arch up more than any other section as they approach the centre. This gives more stability where it is needed.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why is Japan, a country spread across multiple Islands so much more united than the UK, a country spread across multiple Islands." ]
They both *did* have regional identities. The difference is that the UK said "Ok, you can be Scottish, whatever, as long as you help with the Empire and whatnot", but the Japanese said "No. You are Japanese. This is your culture. Now speak Japanese and follows Japanese customs. Do it." There are benefits and drawbacks to each strategy.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why don't car manufacturers make windshields coated with hydrophobic surfaces so that water rushes off and leaves it dry instead of windshield wipers?" ]
To my knowledge, there are no optically clear hydrophobic coatings. additionally, they may not leave the windshield as clear as you might hope to. and it would likely wear off with the constant sandblasting of highway dust. cant wipe away snow, cant use washer fluid. all that aside, good luck convincing the regulators and buyers that they dont need windshield wipers.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why do the Japanese, who are known for having a conservative culture, seem to have such outlandish media?" ]

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why we need people to represent us in the government when we have technology to do otherwise?" ]
Time. QQ before I begin - without going to Google, who is your rep in the House? Your Senator? Your city commisoner? I'm going to guess you got at least 2 of those wrong. Bills which are being considered for vote can be thousands of pages long. There are dozens of those bills being considered everyday in committees and the actual voting floor. Congressmen have staffs of people who's only job it is to help them write and understand the bills that are coming up for a vote. Remembering my first question, do you believe that you have enough time to read thousands of pages a week in order to be well informed enough to vote on EVERYTHING?
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Principle vs law vs theory vs theorem" ]
**Law** - a statement based on experimental observations. Laws don't offer explanations. They just state what has been observed repeatedly. They often involve equations. **Theory** - a theory offers an empirical explanation of the world. It is tested through repeated experiments and observations. A theory also offers predictions, which can be tested to falsify a theory. **Theorem** - Theorems are found in math. They are statements that have been proved using math axioms or previously proved statements (theorems). Unlike theories, theorems are deductive. **Principles** - Are similar to laws. They are often said in their non-equation form. With that said, these definitions are often not followed, and there is a lot of overlap in the naming anyway. Often scientific ideas get historical names that don't follow the definitions, and these names stick.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How can a US execution end up costing $3 million?" ]
The injection itself isn't the issue, it's the perpetual legal battles which will happen in the three decades which will pass before the execution takes place. Appeals filed by the criminals awaiting execution need to be processed and addressed. Lawyers and court systems will be tied up for years, and all of that costs money.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How does snoring work?" ]
> Can i tell if i'm snoring? For the most part, no. Even if it suddenly wakes you up, you're unlikely to initially realize that you were woken by the sound of your snoring. > How does snoring work? Snoring is the sound produced when air passes through your pharynx while it's not fully open. In other words the part of your nose/throat that leads to the lungs isn't totally clear, so as air passes through the airway, it's turbulent and causes vibration. It's similar to how a whoopee cushion produces sound as the air passes between two thin layers of rubber and makes them vibrate.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "In places on Earth where the Sun doesn't set for many months, do plants keep doing photosynthesis for the entire period the Sun is up?" ]
Yes! This is why world record cabbages (and other vegetables) are often grown in Alaska with permanent or near-permanent sunlight. The combination of midnight sun and relatively mild temperatures allows for longer periods of photosynthesis and greater growth. When the temperature gets too high however, photosynthesis declines. Studies of trees of the same species in Alaska as compared with those at lower latitudes show that total annual growth is roughly the same annually, but the Alaskan trees to it far faster in the summer time. Interesting stuff!
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "What happens to the body when we (men) get \"blue balls\", is there another scientific name for it, and why does it hurt so bad?" ]
It's called vasocongestion and happens when blood is "pooled" up in vessels in your scrotum/testicles. When aroused blood rushes down there and if there is no release, the blood stays and swells the area. I get it very easily, sometimes just cuddling next to a pretty girl for a bit (unless I crank down before we hang out) will cause it.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why do some construction projects take so long?" ]
Manpower is crazy expensive. It is by far the most expensive part of almost any construction project. If 100 guys can do in an hour what 10 guys can do in 9 hours, you hire the 10 guys. Every truck in that video has a driver in it who is spending most of his time sitting around waiting for the other trucks to get out of his way. That's a costly inefficiency. So unless you absolutely need it done fast it's almost always cheaper to do it slow.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "If all fingerprints are unique and earth has 7 billion people. How is it possible that there are 7 billion unique fingerprints? Are the possibilities infinite? Before we are born, how does our DNA know our fingerprint isn't being used by another person?" ]
First off, DNA doesn't directly affect fingerprints in the way you might think. Fingerprints are the result of chemical reactions in the womb; this is why identical twins have different fingerprints. There are way, way more than 7 billion different combinations. Many estimates put it in the 10^20 range or higher. Now, is it possible for two people to have the same fingerprint? Yes, it's possible -- but for law enforcement purposes, it's pretty much a slam dunk, because there will almost *always* be some other evidence or fact that connects them to the crime. It would be hard enough to convince anyone of a one in a bajillion chance of someone with the same fingerprint robbing the bank. It's even harder when you were known to be at the bank the day before casing it out.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "What is vevo, and why do all the music you tubers use it?" ]
**TL;DR** In order to avoid legal troubles of posting music companies' content on their website (Youtube), Google set up VEVO so music companies could control their monetization. [Link](_URL_0_) to a response by a YouTube software engineer who worked on the Vevo launch. > Youtube/Google was in danger of being sued by Sony Music/UMG music. To prevent a potentially devastating lawsuit, Google's CEO (at the time) Eric Schmidt made a deal with Doug Morris, CEO of Sony Music, to build a parallel video platform based on YouTube tech where Sony could control the monetization settings and sell their own ads. Vevo V1 was basically a shell website that hosted an embedded YouTube player which in turn loaded Vevo's own ad module at runtime. This allowed YouTube to keep the music video content, provided a link was present to the 'official' Vevo page (effectively, a rebranded YouTube page.) The videos were still hosted on YouTube.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why is Meth more pervasive in suburbs/rural communities and Heroin in more urban ones?" ]
I do not know if that is true, but I do know making meth stinks up to high heavens, so areas with low population densities are easier for hiding its production. Heroin needs to be shipped from more or less tropical areas, so if you're shipping it anyway, might as well bring to areas with high population density as then there are more customers nearby.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How is it that Americans spend the most per student out of any other nation, yet there are constantly problems with school budgets?" ]

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why is Mozart considered the greatest ever musical genius?" ]
Highly, highly subjective... But much of it would be attributed to his exceptional gifts at an insanely young age. When you and I were learning how to tie our shoes he was transcribing hour long choral works in the back of a carriage ride home. So a lot of Mozart's "hype" for lack of a better word (not that he *isn't* a great genius and *doesn't* deserve it) stems from his incredibly prodigious childhood. He was actually terrible with money later in life and a bit of a flake by many accounts:)
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Restarting a computer" ]
In a modern computer, the whole system is on the entire time during the reset. Telling the computer to reset makes it to go through the shut down process unmounting drives and the like, but at the end it doesn't tell the power supply to turn off as it would when pushing the power button. Instead, it orders the CPU and RAM to go back to a cold boot mode, essentially dumping whatever is in memory and reloading the BIOS/UEFI.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How is there only one speed of sound? If I shout louder, why is there not more energy leading to a faster speed?" ]
Think of throwing a rock in some water. The ripples made move outward at a given speed. Throw a much bigger rock (more energy) and the waves are much bigger but again propagate (move) outward at the same speed. Similar to sound. And light. A bigger light... Say a million candlepower spotlight, doesn't go any faster than the light from a birthday candle. But also note that there IS more than one speed of sound. The speed of sound depends on the density of the air it passes through, and that is about 340 meters per second, 750 miles per hour at sea level. It is slower at higher altitudes where the air is thin and faster through things like water... 4 times faster. It travels 15 times faster in iron. So the speed of sound depends (partly) on the density of the medium - the stuff through which it passes, not how loud you yell. _URL_0_
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why do most big birds fly away when they see a human but small birds don't really care?" ]
Big birds are, ironically, in more danger. The bigger the bird, the longer it takes them to get airborn, and the more likely they are to be on the menu. Small animals generally aren't worth the trouble to catch, especially because they're light and fast. The little birds aren't afraid of you because they know they're not worth your time to catch, and anyway you're too slow to catch them anyway. Larger birds know that they would make a decent meal and if you got close enough you might be fast enough to grab one.

The original article by a black woman pointed out that Santa is a fictional character and can be (and has been) portrayed as belonging to any race, then maybe there should be more diverse portrayals in the US media since the non-white demographics are growing. Then the right-wing media fell all over themselves insisting that this fictional character is always and must always be pureblooded lily white. *Their* emotional response is what the kerfuffle is about. FNC and other right-wingers always deny being racist yet are strangely threatened by the idea of non-white fictional characters for children.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "What causes the \"fingernails on a blackboard\" sensation? Why does it feel so horrible?" ]
The amygdala is to blame for the cringe. The amygdala associates emotions to memories and stores them in long term memory (hippocampus). There's two theories, one evolutionary, and one physiological. Evolutionary Theory: The sound resembles a cry of alarm at some point in the evolutionary lane. Physiological Theory: Due to the shape of the ear canal, and the frequency of the sound-wave, it causes the frequency to resonate within the human ear canal, causing it to vibrate violently. Both cause a rise in activity of the amygdala, leaving some to suggest that it's recognized as a form of distress signal. On a related note: It has been suggested that the physiological theory possibly correlates to a dog's reaction with high-pitched 'dog' whistles.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why does lightning often occur in 'double strikes'?" ]
Lightning first comes down in a flurry of haphazard lines trying to find the path of least resistance to the ground. This is called the lead. When the lead finds the path to the ground, you can see a very quick flash move up the lead into the cloud. This return stoke is the full strength of the lightning strike transferring power to the ground, like traffic moving forward at a fresh green light. Once that return stroke makes its trip up the lead, the cloud gives it more energy, making the second flash you see

Those flashes of commercials occur in situations where your local station is showing different commercials than the national broadcast that they're receiving. Sometimes the timing gets off, and you get a small snippet of the national broadcast commercial before your station overrides it with their local feed. And no, the advertiser doesn't get upset, because you were never supposed to see their commercial in the first place. Often, it'll be for something like a chain store that doesn't even exist in your area.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why are all drugs \"bad\"? Why can't there be a drug that gives intense pleasure/euphoria (heroine, coke etc) but has 0 adverse effects?" ]
Drugs create highs by manipulating chemicals our bodies produce normally. Frequent drug use can change the way our bodies produce and utilize these chemicals, causing our bodies to produce too much or too little. There is no perfect drug because any substance usage takes our bodies out of chemical equilibrium, causing adverse effects. Edit: Wow! This blew up.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "why does looking at the sun hurt your eyes but indirectly not so much?" ]
Ask your best friend to place their mouth directly in front of your right ear hole and say your name loudly. Then, ask them to place their mouth at your left ear and do the same thing--only this time, instead of having their mouth facing directly at your ear hole, have their mouth face the tip of your nose. Which one "hurt" more? The first one, of course. The reason is simple: the pupil of your eye acts exactly like the hole in your ear. It is the tunnel through which the signal (in your ear's case, sound; in your eye's case, light) travels and stimulates your brain. By staring at the sun directly, you are overwhelming your receptors with signal because light is streaming in directly through your pupil--in the same way that your friend's voice felt like it rammed into your right ear. When the light is indirect, you're getting a "sense" of the signal without overwhelming your sensory receptors. Or, in the case of your ear, you're hearing the sound without feeling like someone jammed a Q-tip into it.

Her appointed representative to which she 'chooses' to defer in all matters is the Governor General of Canada. The GG 'chooses' to be more of a figurehead that rubber-stamps what is required of him or her.

I'm going to use the word "allege" because the investigation is ongoing. There is a town on the New Jersey side of the George Washington bridge called Fort Lee. It is alleged that because the mayor of Fort Lee did not endorse Chris Christie in his campaign last year, Christie's staff arranged a fabricated "traffic study" that closed lanes on the bridge on the Fort Lee side, causing people to be stuck at the bridge for many hours.

For years the processing power for computers have been following Moores law where processing speed doubles about every 18 months and processing power is proportional to the amount of transistors in a chip. However as these transistors gets smaller quantum effects such as tunneling starts to kick in making it very hard to create smaller transistors. currently the smallest transistors are 7nm and experts predicts that the smallest we can get is about 5nm.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Where does my local dealer get controlled narcotics like Xanax and Codeine?" ]
I am sure he is not buying them by the case. He is getting them from people who get fraudulent scripts from shady doctors, who then get the drugs from a shady pharmacy, and sell the drugs to him. What's more, oftentimes these folks are on medicaid, so they get the drugs free, and sell them to the dealer at pennies on the dollar vs what you would have to actually pay the pharmacy for them. That is why up in Harlem, you can buy xanax from a dealer for about 1/2 of pharmacy price, and the dealer is still making a huge profit. in the 90's i had no insurance, and my wife had a xanax script. We filled it once, kept the bottle, and from then on just bought xanax on the street and kept them in the prescription bottle in case we ever got frisked. Street prices were a life saver.

There is no one answer. But a common theme is that it is a release, that comes from a sudden build up of energy. A few things can trigger it. A sudden shift in status. aka A person falling down, Or the queen farting. Or a good joke is generally when two separate ideas collide together quickly. Like... Wife: Honey did you miss me? Husband: With every bullet I have. Another example is when you hear something that is so "true" it makes you laugh. That is because when you hear something that really resonates with you, and you have super fast mini aha moment, if it's fast enough, the release of energy, will bubble up as laughter.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Who decides what country is allowed to do what on the moon/other planets, or is there one institution always having the final word in these decisions?" ]
This is determined by the [Outer Space Treaty](_URL_0_), which was signed in 1967. In short, this treaty (signed by 107 countries currently) says that nobody will put nuclear weapons in orbit/space, and that nobody can claim moons/planets/etc for their own country. Space politics aren't explicitly policed by any one institution or country, but rather by mutual agreement to not be dicks in space. Funny enough it doesn't say you can't have any weapons in space, just not weapons of mass destruction. I'm sure there's guidelines on space warfare in there, but there's nothing exactly stopping a country from putting X-Wings in orbit.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why is everything spinning?" ]
Electrons don't orbit nucleus. That's a simplified version of the atom taught in elementary (secondary?) school. (On a slightly unrelated note, electrons do have a property called 'spin', but that is just a name for it, and they aren't usually seen as spinning) As for why do larger structure spin. When things like galaxies are forming, there are areas with more 'stuff' so things around them get pulled towards it. Since there isn't just one 'lump', different parts of the galaxy will be pulled in different directions. It is unlikely for the momentum of this to cancel out to be exactly 0, so the galaxy picks up a spin.

This - _URL_0_ - is my 3rd degree burn. If I don't stretch it, the colour is pretty normal. I got it in Feb 2012 and it's taken until now to be back to a normal colour and not red. A lot of burns appear to affect a larger surface area, hence more scar tissue is formed to heal the wound.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why aren't electrical prongs hot when they're removed from an outlet?" ]
Heating occurs when there's a significant amount of resistance. Significant resistance can occur if the material you're using is a poor conductor, or if you're using a conductor that's physically too small. In the case of the prongs of a plug, they're both made of metal (good conductor) and fairly large in size. Therefore, there's no major resistance, and they don't heat up noticably.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why do children seem to be better at learning second languages than adults?" ]
There is an area in the brain that is responsible for language processing. It is largely responsible for learning new languages when a person is still young, but becomes "set" after a certain age. After that, we can still learn languages, but the part of the brain that most receptive to that is no longer as efficient.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "why are adobe products so expensive?" ]
There are many reasons why: Adobe's softwares are the results of a long time of research and programing, they are to say the least, products of great quality and gives other businesses tools to create their activity and make profit for themselves. Adobe's consumers are mainly businesses and they can afford a larger cost than individual people, the price is chosen in order to make adobe's products professional more than personal, the bigger your business is the most expensive it gets. Adobe changed how they priced: before you bought photoshop for example but now you monthly subscribe and you get many of adobe's products with photoshop, like premiere, after effects, indesign, illustrator, etc... And adobe's cloud capabilities. Adobe also gained a reputation, because their products are well known and give a certain level of quality, Adobe can easily rise their prices without risking a huge fall of their clients.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How does one hack Gmail and Facebook accounts and how should one protect them to have maximum security?" ]
Typically, it involves guessing the password. Or, if you've re-used the password on a site that isn't as good at security as Google or Facebook, some other site gets hacked and they try the same username/password combination elsewhere. There are two things you can do to really protect yourself. First of all, use a strong, unique password, especially for sites that give access to important things, like your email or bank passwords (your password for some random forum probably doesn't need to be that strong if you aren't re-using it). Second, enable two-factor authorization. Two-factor authorization requires something you know (your password) and something you have (either a security key or your phone usually). For example, when I log into my Google account on a computer I've never used before, Google prompts me to enter a passcode that's generated by an app on my phone that changes every 30 seconds. Even if someone guesses my password, they can't get into my account without my phone.
[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "why do British people sound British while talking, but sound like they are from America when singing?" ]
When people sing, they tend to enunciate more clearly. This could explain why British people sound more understandable to you when singing. However, there are many British singers who DO use their typical enunciation when singing, and their accent is more identifiable. Take for example the music of Lily Allen, The Clash, Frank Turner, and many other popular musicians. Also, many British rock bands tend to imitate the singing style of their favorite acts, who are often American. As for Americans sounding sing-songy to Brits... I doubt it.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why was cannabis ever made illegal in the first place?" ]
There are lots and lots of urban legends and rumors surrounding this impetus of the 1937 Marihuana Tax Act, including pressure from pharmaceutical companies and the paper industry. Although these industries benefited from the act, there's no real evidence that these were the primary factors. In reality, the association of pot with a particular ethnic group was to blame. In the case of pot, the drug was associated with Mexican immigrants, notoriously conveyed in the fact that marijuana, with the silent 'j', became prominent around this time in an effort to associate the drug with the Spanish language, when previously it was often spelled 'marihuana'.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why is it more difficult to run for long periods of time when exercises like biking are just as strenuous?" ]
It's all about practice. You use different muscle groups for different kinds of exercise. Running is *really* hard on your body. You're obviously using your leg muscles, but you're using a whole bunch of other muscles that you may not be aware of. Abs, arms, back, neck, they all play into it with running. Bicycling, you're sitting down, for one. You can also stop peddling for a bit. And you have different gears. Not to diminish from cycling, but it's not really as strenuous as running.

I had chickens growing up and now have a backyard flock for eggs and occasional eating. I try not to eat factory farmed chicken. While they are just about the stupidest warm blooded creature on the planet - they can feel pain, fear and certainly react to stressful situations. I kill and eat all kinds of animals - I'm not squeamish about the reality of the food pyramid - but there's no reason to torture what you're about to eat in order to keep prices down. It's really just wrong. It's bad for the animals, it's bad for the environment and in the end it's bad for our health. My backyard chickens are "happy". They come running when I go outside, they get exercise, tasty food and seem to enjoy life as much as they can. Are they smart? Hell no, they're really really stupid. Do they deserve a good life? Yes.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "Why is the term \"Caucasian\" applied to all white people, regardless of whether they came from the Caucasus region?" ]
In the early 1900s it was believed that white people originated in the Caucasus mountains. At the time, the three "scientific" classifications were Caucasoid, Negroid, and Mongoloid. (Some people still use mongoloid or "mongo" as an insult to this day.) There's no real scientific basis to this, and no way to draw a dividing line. If you were to divide races scientifically by amount of genetic variation, you'd find it looked something more like this: * non-Bantu sub-Saharan people like the Bushmen and the Mbuti (four or five races) * everybody else Which shouldn't be surprising, since the non-Africans descended from a few waves of migrants who only carried a small amount of humanity's total genetic variation.

I'm going to make some mock-code here. This is not real code, this is just so you can understand basically what's happening. object Bird { centerX = 50 centerY = 50 width = 20 height = 20 } building.frontEdge = 100 (X coordinate) while (inAir) { centerX = centerX + (whatever physics calculations here) centerY = centerY + (same. Calculations to move the object in an arc) bird.frontEdge = center + (width / 2) if (bird.frontEdge > = building.frontEgde) (If the front edge of the bird is greater than or equal to the front edge of the building on an x-coordinate graph) { do whatever for a collision } In reality, it's much more complicated, as the objects aren't prefect squares, and the physics calculations are more defined, but that's basically what happens. The bird is kept track of, where its shape is defined as different coordinates. If any of the coordinates are the same as the coordinates of the object it's supposed to hit, then a collision has happened.

The fact that it only works as one of those at best. Usually it’s just body wash with maybe some additives and fancy marketing. If you want to treat your skin and hair well, use three separate products that actually do their job. Every persons skin and hair is different and the idea of a one-fits-all and all-in-one product is ridiculous. Especially the shampoo-conditioner combo is nonsense since those two products literally do opposite things. Shampoo cleans your hair from the oils that accumulate on it and conditioner puts some amount of oil and moisture back on it.

White privilege does not mean that ever single white person enjoys advantages over every single person of other ethnicities. It's mostly referring to two things: * White neighborhoods are, in general, better off economically than minority communities - and tend to receive better education/police services. * Racism is subtle, but real. Little things like promotions at work, traffic stops, you name it - individually they're often in grey areas but in aggregate they show a clear preference towards whites. Those sort of things are also somewhat regional. Some regions of the US are fairly integrated and more beyond that stuff, some *way* less so. A wealthy family immigrating into a well to do integrated neighborhood in SoCal or something probably won't see that, but that's not exactly the typical experience of immigrants from Latin America.

[ "Provided a user question, retrieve the highest voted answers on Reddit ELI5 forum", "How are rock songs constructed?" ]
> How exactly does the guitar interact with the bass, rhythm and vocals. Generally speaking, one instrument (most often the guitar) plays a lead melody, while all other instrumentation and vocals play harmonically-compatible parts which *support* that melody. On their own these supportive instruments do not play parts that could be considered distinct melodies, as they're designed to accent the lead melody. More complex rock music, and a great deal of music from other genres (such as classical or technical death metal), will feature instruments playing completely *separate* but harmonically-compatible melodies, each of which could stand on its own as a distinct melody.

Well usually we see it in movies in the context of the first volley against a force moving towards the wall. In that case the commander can simply say 'on my mark' if they want the arrows to start only when the enemy forces are close enough to get a reasonable hit on with the arrows. Also it's a lot more devastating to morale to have them all hit at once. The perception of a well-coordinated enemy is itself disheartening but also it means you're getting this rain of grievous injuries all hitting together so from the perspective on an enemy foot soldier there's just waves of death causing quite a few of the guys around him to start bleeding out all at once. Has a bigger sense of impact when you get all these injuries hitting together.

It depends on the exact nature of the new law. All else being equal, they may still be convicted, or if already convicted may still be imprisoned, because they broke the law *as it stood at the time*. However, recognising that this is kind of silly where a law is introduced that basically says "welp, we shouldn't have had that other law in the first place", legislatures may put provisions in the law that cause pending prosecutions to be dropped, and may even automatically commute the sentences of people already convicted. This, though, is by no means guaranteed. All of that actually applies to *anything* that becomes legal after having previously been legal, not just possession of cannabis.
