how Americans are okay with insanity they call insurance companies | There is. Pretty much everyone hates the insurance companies. But half of us don't think that any of the proposed alternatives would actually be any better. Also, for the majority of Americans the healthcare system is actually quite good, despite what you see on reddit. Quality care is available without significant del... |
Why does electricity conduct better through different materials? | In a metal the electrons 'float' in a sea around the nuclei, they are not bound to a specific atom. In wood each electron is mostly bound to a specific nuclei. The flow of electricity depends on how free the electrons are to move around. |
Why is it advised to cut down on salt when one is bodybuilding? | Someone can feel free to correct me, but I believe this is due to the osmosis of the water in our body. With too much salt, the water in your body will retain more making you look bloated. Potassium helps this, because then you will have more potassium for the sodium potassium pump. So the salt or sodium will be remove... |
How are acids named? (Chemistry) | It's a combination of systematic naming and what's always been done. If it's an organic acid, that is, it has a carboxylic acid group in it attached to some number of other carbon groups, it is named based on the IUPAC naming scheme, for which wikipedia is probably your best explanation. Examples of organic acids you m... |
Rhythmic modes in Medieval music | I could be mistaken, as I'm not overly familiar with older forms of music theory, but I thought medieval rhythmic modes were just the first attempt in history to denote rhythm *in the written form*. Prior to the advent of medieval rhythmic modes sheet music contained pitch information, but the rhythm of any particular ... |
How did 'John/Jane Doe' become the generic name for an unidentifiable person? | In English law before the 19th century, there was a lot of emphasis placed on very technical matters. This often led to the real issue not nicely fitting in a standard lawsuit form. For instance, if you had a dispute with someone about who owned a piece of land, you couldn't really sue them directly to argue that . Ins... |
When upside down, how are you still able to swallow. | Peristalsis. That is the name for the contraction of myscles that forces food along its path. It is what allows you to eat upside down and what allows astronauts to eat in 0 g. Incidently, not all animals have it. Birds dont, which is why they tip their head up when swallowimg and why we can't take birds into space.Mus... |
How do ad networks work? | Ad networks generally have agreements with a lot of popular websites. The ad network pays the sites to place their ads, and vendors pay the ad networks to display their ads in those spots. When / if you click on one of those ads it brings you to the vendor's website. The ad network tracks where you saw the ad, when you... |
What determines if you are burning fat, muscles or calories? | I assume you meant > What determines if you are burning fat, protein, or carbohydrates? It is dependent on a number of factors, the type of exertion does not matter. Running or weight lifting alone do not determine which energy source your body uses. As I think you meant to say, there are three energy reservoirs our bo... |
Why are you ordered to register as sex offender if you are peeing in public? There is no sexual matter involved in peeing. | There is no sexual component in peeing, no. But there is a sexual component in purposely showing your genitals to other members of the public. The thing is, it can be very hard to gauge the motive someone had when they were peeing in public. Were they genuinely desperate and couldn't wait, or are they peeing there beca... |
Why do you bite your tongue, cheek or lip while chewing? | We use our tongue and cheek to position and rotate the food between our teeth. When we push a piece of food the wrong way or overestimate the amount of force needed to position the food, we bite ourselves. Chewing wouldn't work so well if we were just chomping up and down letting the food fall where it may!", 'I think ... |
How did we develop all this advanced technology in less than 300 years when it took us hundreds of thousands just to learn how to farm? | The major catalyst was the industrial revolution in the late 18th and early 19th century. Political stability and the ability to efficiently produce food were contributing causes to the industrial revolution happening.Technology is a multiplier, not an adder. In other words, if you wanted to add a long list of numbers ... |
Why do planes need to be pressurized? | At high altitudes the atmospheric pressure is very low - there's less air than there is down at the surface. If the plane wasn't pressurized there wouldn't be enough air to breathe. |
Why Do Movies Shot 30 Years Ago Look “Old” When Played Now? | Technology in camera equipment has come a long way. Lenses have gotten better. Lighting has gotten better. The art of film has been perfected over the years. But I think the main factor of this "old" look has to do with post production. Back in the 70s and 80s they didn't have the computer power to color correct films ... |
If permanent colonies were built on the Moon, how would someone born there be effected on Earth due to the differences in gravity? | The moon *does* have gravity. It's a lot lower than Earth's, but it's still there - a lot more than the microgravity experienced on the ISS. All we can really do is theorise, but the likelihood is that if someone grew up/lived a long time in lower gravity, coming down to Earth would be pretty traumatic. Your bones and ... |
Self driving cars become common. Who is responsible for crashes and accidents? | It is impossible to answer this question. The laws / terms of insurance have not been written yet. Like so many things, they probably won't be written until the first accidents start happening. |
why does water taste so sweet after vomiting? | I'd say there are a couple of reasons. Firstly, the water washes away the acid residue left over in your mouth by your stomach fluids, causing relief of the burning sensation and that might be perceived as sweet. Also your body is most likely craving water due to the sudden onset of dehydration that was probably caused... |
What is the actual purpose of having a United States Space Force? | I think the idea is to split the responsibility for space off of the Air Force, much like how NASA was split off for civilian aerospace work. The Air Force actually spends more on space operations than NASA . Putting that as it's own organization would, in theory, let them focus on the core mission better. Not really s... |
Why baseball stadiums are different sizes | Tradition. And more than any sport, baseball is a slave to tradition. When professional baseball was in its infancy, there were no dedicated stadiums. Teams would play wherever they could find the space, usually somewhere used primarily for something else. The Yankees, for example, used to play on polo grounds. This le... |
Why does your skin heal faster at night than during the day? May it be for cuts, wounds, spots, acne etc... | Because your body's resources aren't dedicated to moving you around, talking, seeing, etc. Also because you're not moving around, touching your injuries and generally making things worse. |
What causes blood to seep out of cuts and scrapes? | For blood to come out of a wound, some kind of blood vessel must be damaged. If the cut or scrape is very small, then these blood vessels were likely capillariesBlood vessels come in a variety of sizes based on their exact purpose. Veins and arteries move blood around the body after being pumped by the heart. If one of... |
- What are undersea cables, and how do they work? | Undersea cables are made up of bundles of fiber optic cables running along the ocean floor that connect different parts of the world to exchange data/internet communications and telephone conversations. The first submarine cable was laid all the way back in the 1850s and was used for sending telegrams. Obviously, the c... |
I was always told not to put a fridge or AC on an extension cord. Why? | Refrigerators and AC units have a much higher peak power draw than most household appliances. An extension cord that isn't rated to handle that kind of draw could overheat and short, or cause a fire. |
How are humans able to talk and hear their voice inside their head? | Something to do with the brain neurons that ultimately leads to consciousness. Consciousness is still a mystery unsolved -- no one really knows what it is, how to accurately define it etc. But that voice inside the head operating while you carry out other automatic or semi-automatic functions are part of your conscious... |
in the USA, when does a dad (or mum) in full time employment see their children? | You work 9-5 in a lot of jobs, meaning that you see your kids in the morning and evening. |
Why does it hurt significantly more standing on a 10 min bus ride, over walking for 20 minutes when commuting? | Standing tends to strain the same muscles over a long period of time. Walking spreads the load over several sets of muscles, so that while you're technically expending more energy no one set of muscles have to bear the load for the entire period.Static postures cause lots of things to occur - but mostly it almost alway... |
- Can things like light waves or radio waves become radioactive? | Light and radio waves are both kinds of radiation. Specifically, they are both non-ionizing EM radiation. What "non-ionizing" means is basically that they won't come barging in and jack up your DNA. X-rays and gamma rays on the other hand are ionizing EM radiation, and definitely will smack your DNA upside its head. So... |
What changed that allowed SpaceX to go from crashing rockets on barges to a 3 for 3 success rate? | Every crash is a learning opportunity. They weren't crashing because they didn't know WTF. There's a ton of very complicated stuff to work out to land a rocket, and getting it even a tiny bit wrong usually results in an explosion. Rockets don't really do rough landings. It's either perfect, or kaboom. So every time the... |
Why can't fresh water fish survive in salt water, and vice versa? | Many fish can, and do. Salmon, for example, make babies in fresh water. The babies swim out to sea and grow up and get big and strong, and then they come back to fresh water and make more babies. They have this ability because over millions of years, they were able to have more babies in freshwater than saltwater. That... |
Why is there ice in the mens urinals | Ice cools the urine which reduces odor. Ice also melts, which produces water and flushed the urinal. Much more popular back in the days before auto-flush systems.I'd also say that they put it there as 'entertainment' and and as a way for people to keep it in the urinal. ", 'Also assists in preventing splashback onto yo... |
What is a "housing bubble" and why did it crash a few years ago? | A housing bubble is when the price of homes in a market rises unsustainably. Banks started loaning money to people who realistically weren't going to be able to pay the mortgages back. Too many of them failed to pay their mortgages, and were foreclosed on, and it crashed the market. This problem was exacerbated, by the... |
How do other animals cut their nails in nature? Do they even have to? Also, how did humans cut their nails in the past? | Usually just using them makes them eroded and they are as long as you need them. In nature, animals and humans use their nails for lots of things, and there is where they are "cut": every time they are used, they are a little bit shorter, making up for their growth. If they grow too much, they can be scratched against ... |
why do people with accents lose their accents when singing? | Because when they sing, they are consciously controlling their voice and producing a particular phonetic effect. Like you would if you're imitating birdsong. They are in very good control of their voice, and can produce specific desired sounds rather than speaking/singing in their natural accent. |
Why we still label circuits based upon "conventional" current when we know that current actually flows in the opposite direction? | Pretty much, everything was defined before the discovery of, say the electron. Scientists, being positively minded and optimistic, decided it would probably be the positive charge moving around. Note also how stuff like Capacitance is measured in Farads, which is a huge unit and you usually use micro or nano farads bec... |
What's the fastest way to cool hot liquid? Is it faster to cool hot liquid by pouring it over a cup of ice or by pouring ice into the hot liquid? | So cooling is all about surface area. You want the hot liquid to be as exposed as possible to the thing its bleeding its heat into. Whether you pour the ice or liquid in first is unimportant. What's important is the amount of the ice's surface that's exposed to the liquid. If the ice is in a single block, it will cool ... |
How do tattoo's work? | The tattoo is a hollow needle that basically stabs you over and over really fast and drips colorful ink into the place it's stabbed you. It has to go deep to the dermis because that's the permanent part of your skin, you keep it for life. You're constantly shedding little bits of your epidermis, so if you put tattoos t... |
Why do Stores and restaurants in US cities, often in lower income area, all have a very similar style? | In the US, there is not a strong tradition of going to the nearest store, rather than the one you think will serve you best. So stores are trying to draw in new customers who only pass by occasionally. Extremely bold and informative signage has proven to work. |
Why are there different sized stars? Once enough mass is gathered to commence fusion shouldn't additional gasses be blown away from the star? | The gas clouds that stars form from collapse into a disc shape pretty early on in the formation process. The big-ish protostars blast most of their early heat of formation out in polar jets that never cross that disc, so the incoming matter doesn't meet the outflowing energy until the star is well formed. It takes some... |
Why do online job application systems force me to attach my resume and then also fill out their own resume system? | The parts you have to fill in will be run through their HR system, which can make a preselection. With how many people apply to some jobs, there simply is no time for them to check out all resumes, so they have to select them some way. Once you are through the preselection, your actual resume makes it onto the desk of ... |
If cold humid air is more cold than dry air, but hot humid air is hotter than a dry heat, what is the tipping point? | A person's perception of temperature is a bit complicated by several factors. Except for extreme heat, your temperature is going to be lower than the air temperature, so it is a matter of how much energy it takes to warm the air up and cool you off. At low humidity, the air requires very little energy to change tempera... |
Why do so many people hate Piers Morgan? | I don't watch his show, so I don't have any strong feelings about him. From what I have heard from other people, there are two major complaints: 1) Back when he was in the UK, he had a reputation for publishing inaccurate, sensationalist content as news. 2) On his show in the US, he is viewed as arrogant and condescend... |
Traditionally, Where does the responsibilities of the CIA and Pentagon begin and End in relation to each other? | Accountability and Authority. CIA is responsible for Intelligence abroad , as well as clandestine operations. The Military is a large scale force that requires Congressional oversight and is expected to follow strict protocols such as the UCMJ and things like the Geneva Convention. Whereas a CIA operative can infiltrat... |
How does Apple own the Beatles? | [The Beatles sold the rights to their catalog of music back in the 1960s.] It's been owned by many people, most famously by Michael Jackson, who made almost as much money on Beatles royalties as on his own music. I don't know if Apple Computer has any ownership in Beatles music, but you might be confused by [Apple Reco... |
How does the software "Tor" work? | Here is a little diagram to start off with:_URL_0_ The basic gist of it: You connect to the network which proceeds your request along a randomized route through network-relays using data encryption, before it transmits your request to the final destination. Backtracking is extremely hard, since the randomizing algorith... |
Why is it often recommended to fully charge electronics before using them for the first time? | Imagine that your battery is an opaque water bottle. When you first get it, it has some amount of water in it. You have no idea how much water is actually in it because you can't see the water. It has a weight to it but that doesn't tell you anything because you have no reference. For all you know, it could be empty or... |
Why are symptoms more potent in the morning and evening when you are sick? | In the morning it's usually because you've been dehydrated due to sleep or if symptoms just arose, you aren't used to it. In the evening, because of being tired and talking all day, you get worn out. Just think of going to a sporting event all night yelling then getting home and having a sore throat. Wear and tear of e... |
How did the alpine tunnel makers ensure that when they bored through the mountains they came out where they intended or met the other diggers coming from the other side before the days of GPS? | Not only from the days before GPS but GPS does not work inside tunnels so they still have the same problem. The way you do this today is that you use lasers to measure the distance and angles of the tunnel walls. You put down special reflectors into the walls of the tunnel and measures their position to the other refle... |
How to people find amber with preserved life inside? | It’s just random. They mine the amber and then upon examining it and cutting it up to sell, find what’s inside |
Why does 80 degree water feel so much colder than 80 degree air? | Water absorbs much more heat per volume. So water touching your skin aborbs more of your body's heat compared to air of the same temperature.Water has a much higher specific heat and massively more weight than air. What you perceive as hot and cold are usually heat transfers rather than actual temperatures. Thus water ... |
Ugly power lines, poles, transformer cylinders and other mess of stuff cloud my neighborhood. But my well-off parents' neighborhood has not a single wire in site. How? | All those things can be run underground, but it can cost up to 10 times more than overhead systems. This cost means that they tend to only be put underground in regions where people are willing to pay that price, ie wealthy neighborhoods.Lots of comments about the price which is true. One other factor I want to mention... |
Congratulations ELI5 on 300,000 subscribers! And thank you! | I enjoy seeing the questions people post. Sometimes, i feel like just replying "google it," but then i realize that a lot of times, even if you do google it, the answers you find require you to either know a lot about the topic to begin with, or are so buried that you may never find the answer you are looking for, so i... |
Why is it so hard to spot this "Planet Nine" when we can easily observe and photograph light years far off celestial bodies? | Well first of all, we can't easily observe and photograph most celestial bodies that are lightyears away. The ones we can photograph tend to be either giant flaming balls of light, clouds full of giant flaming balls of light, or a collections of billions of giant flaming balls of light. You might notice the recurring t... |
How does paying for windows 10 work? What's their plan, im confused by the whole thing. | Microsoft wants everyone in their app selling environment more than they want to cling to the idea of home users paying to upgrade windows. The app environment sells things like google play or the itunes thing. Those environments are huge money makers', "Consumers paying for Windows 10 isn't that useful to them. Most a... |
What exactly happens if Russia is proven to have tampered with the voting process (ex: Brexit, US elections)? | The UK has mechanisms to force a new vote. So they could "revert" things fairly easily if the public decides to do that. The US does not have such a mechanism. They could impeach Trump for it which would leave Pense being President. They could also theoretically impeach Pense as well since he was on the same ticket and... |
What is it that specifically makes the new car smell and why is it the same in every car? | Offgassing plastics. There is some concern that plasticizers and solvents released from many industrial products, especially plastics, may be harmful to human health. All the car companies use the same types of plastics so thats why the smell is the sameWorking in the car industry I can ensure that this smell is: a) no... |
Why is Netflix Throttling such a controversial issue? | It's when the ISP is hand picking what websites are fast or slow that really gets people. It's an incredible amount of power where companies that used to be just neutral pipes to turn into places that hand pick what websites can or can't exist. The fact that many of the largest ISPs are media companies and the sites th... |
how can PPI (pixels per inch) be different across certain devices? Aren't inches and pixels a set size? | an Inch is a measuring unit. a Pixel is an object. It can be any size. A display's resolution describes how many pixels it has. 1080p means it has 1080 pixels on the short side. So, obviously, to fill a 42" 1080p TV and a 5" 1080p phone with the same number of pixels is going to require differently sized pixels.> aren'... |
How will TTP copyright laws affect people in non-signing countries? | It would mean that any web service that operates in those countries would be subject to the new copyright terms. As a person using a web service that operates in one of those countries, you are also indirectly affected by the new copyright terms because presumably all the content made available though those websites wi... |
What does the successful vote to allow the sale of people's browsing history mean for the average person and what is the scope of this? | It really doesn't mean much. The rules that this vote seeks to overturn haven't gone into effect yet. Everything will stay as it is. It's also important to add the the senate vote is what just happened. For it to mean anything at all the house must vote to approve it and then the president must sign it. That will likel... |
why they call dark matter "matter" | Because as far as we can tell it is matter. It's just a special type of matter which doesn't interact at all with the electromagnetic force, so we can't directly see it. **Edit:** Something I want to add, matter that doesn't interact much with EM isn't actually all the strange. For example, neutrinos interact very weak... |
With the attacks going on right now, why has France been the target for so many terrorist attacks? | They, like all the old European powers, had colonies in the lands that are now terrorism hot spots. They treated millions of people very badlyMany Islamic groups are pissed that France outlawed the Hijab |
Does my way of doing this math problem make any sense? | All you did is multiply both sides by the denominator in the x fraction, and then rearrange terms a bit. a/b = x/c c * a/b = x c * a * 1/b = x c/b * a = x |
Why is destructive interference unnoticeable, say if you have two sources of light and you move them around? | The wavelength of light is smaller than the smallest thing a human eye can see, by far. So these effects are too fine in scale for us to see. |
why carbon monoxide is so poisonous to breathe when carbon dioxide is not. | Carbon monoxide binds very strongly to hemoglobin, the molecule that carries oxygen in your blood. When it does so, it stops hemoglobin from binding to oxygen, and limits your body's capacity to get oxygen in the process. Carbon dioxide, which is almost completely non-reactive, doesn't do that. |
How do they turn old black and white photos into color photos? | Unless the negative is preserved, they literally just color it. Think of it as a coloring book. I've tried photo colorization, and while choosing correct colors isn't that hard, getting the blending to work out realistically is much harder. For video, when it's a single shot, you can use tracking software so you don't ... |
What exactly does vigilante justice mean? | In the simplest terms, it means justice administered by individuals , outside of the legal system. It could be a single person "taking the law into their own hands" and attacking a person who committed a crime against them. It could also be a person cruising around trying to punish criminals in general , or it could be... |
Why can speakers be blown out? Couldn't manufacturers just prevent the volume controls from going that high? | Speakers don't affect volume. They can support a maximum volume without blowing out. If you connect speakers to an amplifier that boosts the volume you can blow out the speakers. But they are made by different manufacturers. The speaker company doesn't know you're plugging into to an 800W amplifier. The amplifier doesn... |
How do gemologists tell lab-grown gems from natural gems when the crystal structure is the same? | Naturally formed gems are not perfect. They have atoms of other elements dispersed within their crystal structure. When a gem is grown in the lab, it is usually 100% pure. There are no imperfections, . So when a gemologist observes the crystal structure, and they see no impurities, it is almost certainly lab grown. |
Fire... does it push things or exert force? | Fire itself does not, no. However, fire heats up the air around it which can increase the pressure that they exert. For example, have you ever seen ash from a newspaper floating out of a fire up into the air? It's not doing that because the fire is pushing it, but the air beneath it is heating up and starting to rise w... |
Why are newer smartphones so much easier to break than "old" ones? | The big change has been making the entirety of one side a fragile glass screen. The decision to make the bezels thin means that there is little space to absorb impacts without putting the forces onto that large, fragile glass panel. They try to make the phone strong instead, but the desire to make the phone as thin and... |
How did we discover Pluto? It's so little and our solar system is so huge. | Random chance. We thought, incorrectly, that Neptune's orbit was being influenced by another body. We did some math based on that incorrect assumption and came up with some areas to look at. Then took thousands of long exposure photographs. At least two were taken of each small area of the sky on separate nights. Then ... |
Why does hearing a song lots make us dislike it? | I think you can relate this in a similar way to drugs. When you take a dose of drugs or listen to pleasant music, your brain is simulated and releases signals that it is happy with whatever you consumed. However, over time the same stimulus will result in lower and lower stimulation in the brain, as it becomes used to ... |
if someone comes on your property without your permission and they slip or get attacked by a dog, can you be held liable if they sue? | That fully depends on the country/state that you live in. In some places you can be held accountable for any injury, in some you can be held accountable if there was injury due to your negligence , and in some their trespassing negates all rights to sue you for any injury they get.I assume you're asking in the United S... |
Why is the US West Coast a desert | The west coast is nice and green, but then there are several mountain ranges. Air that is pushed over the mountains is cooled and forced to drop most of its water vapor, so it is much less moist. This means less rainfall beyond the mountains and more desert conditionsThere is temperate rainforest down the west coast fr... |
do antibiotics target individual infections and if so how? | Yes you get certain antibiotics for certain infections. When a cut on your foot gets infected you will get one set of antibiotics, and when you get a tooth infection you get another set. Also you can use antibiotics from your cut foot incident to help with your tooth infection. Antibiotics will help bring down your inf... |
Why are there poor Conservatives? | Don't you ever wonder why there are so many rich Liberals, too? All this "what it means to be Conservative / Liberal" crap that you get poured into your head by the media and your school system and your party-liners is just a bunch of bullshit establishment lies. "Poor" and "Rich" have nothing consequential to do with ... |
What happens to the body when you donate one of your kidneys? Does it become less able to filter stuff out of your body? | When you donate one kidney, or one kidney fails, the other will pick up the slack. When functional, both kidneys are not operating at the fullest capacityYes and no. "Yes" in that your total renal capacity will obviously go down. But "No" in that most people don't make full use of their kidneys anyway. So maybe that on... |
Why do Dutch people eat spaghetti with knife and fork, instead of spoon and fork? | American of partial Italian ancestry here, what would you even use the spoon for? why not just a fork?', "It's easier to eat that way. I'm an American but I've never seen anyone eat spaghetti without a fork |
why does cleaning your ears cause gag reflex? | It does? If it actually does, I would say it’s because the ear, nose and throat are all connectedThat is a pretty atypical response in my experience. I’m no doctor, just a paramedic, but I’ve never ran across any anatomy books, or patients, that’ve mentioned that. Gagging is usually caused by laryngeal spasm. The laryn... |
I have some questions regarding orphanages in 1980's-90's America for my novel. I have trouble finding answers online, some help? | There weren't that many orphanages in the US in the 1980s and 90s. Orphanages were phased out by the 1950s and instead kids were sent into private homes for foster care, overseen by social services such as child protective services, where social workers monitored the children's environment with periodic checks. Day to ... |
The 4 basic assumptions in financial reporting | Economic Entity - The company is a separate legal entity from its owners with its own finances Going Concern - The business is operating with no planned shutdown period. In other words - it's going to keep operating Monetary Unit - All reports are done in a single currency Periodicity - These reports are generated on a... |
Why do humans/mammals bleed from the mouth after head/chest trauma? Why is this always the imminent death factor in movies? | Think of what the mouth connects to - your lungs, stomach, and the passageways to your nose and ears. Head/chest trauma can lead to bleeding into one of those areas, which is usually a sign things are going pretty wrong.No, it is not a sure sign of death. As mentioned, your mouth is connected to your lungs, stomach / d... |
Why does it take so long for a country to develop nuclear warheads/ weapons? E.g. Iran and N. Korea. | It depends on how many resources they want to put into it. North Korea is a very poor country so they can't spare the same amount of resources that the US put into the manhattan project. Additionally usually people who are developing nuclear weapons programs are doing it against the will of the wider international comm... |
Why don't we pronounce the name of a country like the natives do? | We don't speak the same language they do! The English name is often simply different from the native name. The idea that things should be rendered precisely as in the language of origin is very modern. When people were more internationally oriented and less particular about the country they were from, it used to be the... |
Why are we so worried about a plane that has gone missing? Couldn't it be assumed that it's in the ocean as no one on that flight has spoken out? | It's a fairly new plane and they have no idea why it went down. If it was a design flaw it could happen again. If they don't know what the design flaw is, how can we be sure that in the next planes we start building the same flaw isn't there? Or if it was the pilot's fault for whatever reason, knowing why and investiga... |
The recent changes to US healthcare and the changes happening in the near future | **What happens under the Affordable Care Act:** *if you already get health insurance through your job*: Your children can stay on your health plan until they turn 26. Other than that, nothing else changes. *if you don't get insurance through your job*: You are required to have health insurance one way or another. No if... |
Why does rain make the internet slow? | Depends on type of connection the wifi uses, if it is through cable to wifi then the signal will be okay, if the wifi is connected through antenna the connection will get worse because the rain is blocking the signal from travelling from the signal emmiter which causes data loss along the way, so the data needs to be s... |
Why are "normal" bodily functions we all do such taboo topics or exceedingly gross when it's someone else's? | It happened through evolution. A lot of germs or viruses can be transmitted through poop or blood or snot and many other things. If they are your own, you do not run much risk since you already have those germs/viruses within you. But from someone else's: that's like playing the lottery. I say it happened through evolu... |
Why are some meats edible undercooked/raw? | You can get [Trichinella spiralis] from undercooked pork, it can cause intense muscular pain, difficulty breathing, weakening of pulse and blood pressure, heart damage, and various nervous disorders. Not something you want. |
The controversy with Gabby Douglas' hair. | It's not pulled back tight enough, it looks like it was haphazardly thrown together. It's not really a controversy so much as people just paying too much attention to a women's looks yet again. : It's something people with more experience with black hair and are thus those that are calling it out more readily.I think t... |
why does the show "Power Rangers" still have monsters that look like rubber costumes? | Young children are not especially critical of shitty special effectsBecause they are trying to make the shows as cheaply as possible.
