Like you can feel the itch but you can't quite scratch it because it feels like it's inside you, like your muscle tissue or something is itchy ? Does anyone else get this? Do I have weird insects in me? And I dying? |
How come I can get really tired reading a book or watching tv, but when I try to go to sleep immediately after I toss and turn for hours before finally falling asleep? | I can't speak about reading, but I remember reading a study where the glow of a TV screen enters your retina and convinces your hypothalamus that it is still daytime, which inhibits your brains production of melatonin and other sleep hormones. |
How do internet companies that offer large amounts of data storage turn a profit? | Storing data is dirt cheap. It's so cheap that it's actually become cheaper to buy and install new hard drives to store data forever than it is to erase data. Once you have server space, using it is essentially free at the terabyte level. As a result, the tiny ad revenue those sites get off you is more than enough to c... |
If you have a pile of mulch/woodchips/etc and leave it long enough it can start to smoke. How? | Don't take my word for it, look it up . It's probably not smoke from combustion just water vapor . The pile of chips can get pretty warm as it decomposes, especially if theres a lot of wood in the mix. That's enough energy for the naturally wet material to let off steam. Shove your hand deep into the pile, and you'll s... |
Why is battery still required for the car's engine to keep running? | The battery in modern day vehicles is required for 2 reasons: * to provide power for initial vehicle start* to supplement power from the car's alternator under heavy electrical load After you start the car, you can remove the battery and drive around all day , so long as you dont run all your lights, the ac, the radio,... |
How knowing mathematics is important for learning how to code a computer | You can consider programming as a branch of mathematics. Programming functions are named from mathematical functions. SQL? That's just relational math applied. Algorithms? That's discreet math applies. GUI? I use basic fractions a *lot* when working with GUI. So what's the use? Relational maths seems 100% useless to me... |
How do doctors, nurses, etc. tend to sick people constantly without getting sick all the time themselves? | Hmm, I'm not about actual research on this , but anecdotally, I can tell you I got sick far more regularly when working in the hospital, compared to when I took some time off. Same holds for a lot of people I know. Source - Family and friends are all doctors |

What can one do to help the environment? | Just in one's daily routine, recycling is a pretty big thing you can do to help out. It keeps material out of the landfill and helps lower material prices. Recycling your soda cans helps lower the manufactures costs and in turn soda prices. Composting is also a big thing we can all do for the environment. It helps buil... |
Why do militaries paint missiles? Aren't they just going to explode and get destroyed anyway? | The primary reason is for easy identification pre-combat - you don't want the guy loading missiles on your F-16 to give you the wrong one. It's also a morale thing. Paint's not that expensive, and cool, intimidating missiles will give you confidence in your side. |
So are mass shooters mentally ill or not? | They can be, sure. But that's not necessarily the case, and the focus on their mental health is something of a red herring. |
Why exposing a company with factual information can end up getting you sued? | Because the act of being *sued* does not imply that what you did was wrong, nor against any law. In fact, there are more frivolous cases of defamation and slander than there are successful ones. I think what you meant to ask was '***Why does exposing factual information about a company lead to a successful lawsuit agai... |
If climate change is such a massive problem, why can't the government create laws to begin to limit the usage of items that increase greenhouse gases, until they can gradually completely ban it? | You mean remove things like cars, buses, trains and ships? And electric power plants, factories that produce your goods? And the jobs that those industries provide? That kind of talk doesn't get politicians elected.Remember that not everyone even believes climate change is occurring. I, for one, don't believe in it, an... |
How does the concept of Universal Basic Income work? | Think of it this way super simple: To get welfare, we must fund it, then people spend time applying for it, then people have to review, background check, etc etc etc. Cost all around. Universal Basic Income is like this: Everyone in the country gets say $1000 every month per human. The taxes get skewed so that the poor... |
Seriously, what is the deal with airline food? | Maybe I just got lucky, but I've always been satisfied with the food on the plane, for the most part. It was never worse than the food in my school's cafeteria, or my own cooking :) But on a 12 hour flight, I'm happy about any sort of food they give me so I don't die, hehe.It would cost money to serve decent food to a ... |
What's the point of drinking 8 glasses of water a day if I just urinate the majority of it? | That's more water than you really need. Still, urination is important - it's one of the major ways your body gets rid of chemical waste.We drink water because it enables us to flush salt build ups out of our body. So we drink BECAUSE we pee it outIf you force yourself to drink lots of water in a day, it will make you l... |
You couldn't kill bacteria with 102° water, so why does your body heat up while you're sick? | Unsurprisingly, it's about temperature. Enzymes have an optimal temperature. This is why warm-blooded animals have better strength, endurance, and energy than cold-blooded animals. This comes at a cost, though. There is a slow drop-off of enzyme efficiency as the temperature drops, and a *sharp* drop-off as temperature... |
If women have a right to their own bodies, why is abortion legal, but prostitution illegal? | This is a question that many advocates of the legalization of prostitution also use. It's a fair point. Though a counter argument that hasn't yet been mentioned is that frequently, prostitution isn't entirely free choice. Rather, they are coerced by pimps, or trafficked and kept prisoner. These practices undoubtedly ha... |
how do people (Tom Petty Gaye family) win copyright battles over songs with loosely similar melodies? Haven't all the basic pop melodies been used a thousand times already? | Paying seven million dollars to his kids doesn't make sense to me either.Copyright includes intent, and there was a recording of them saying they wanted to make a similar song. |
Why don't copyright laws affect China? | I believe that it does, as China has ratified the [Berne Convention], but they don't have a quick and easy takedown method like the DMCA, so you would be required to file a lawsuit, which can be very costly. See also: [Intellectual property in China] |
The "jet fuel can't melt steel beams" conspiracy, it's plausibility, and scientific evidence related to the conspiracy. | The temperature that jet fuel burns at is less than the temperature that steel melts at. This is a true fact. Conspiracy theorists claim that because this is the case the world trade center buildings shouldn't have collapsed and this is a sign of an inside job. What they fail to take into account is that as metal becom... |
How Can Viewers Be Influenced by Unrealistic Standards of Beauty in the Media, but Not By Violence in the Media? | Who says we are not influenced by violence? I don't think it makes us more violent, on the whole. But I think it makes us more accepting of the violence done in our name . |
why when I eat spicy food my poop turns into water. | They're not even liquid poops. They're just ass-piss.I believe this is what Johnny Cash was singing about in his song "Ring of Fire". References to "love" in the song are just a euphemism for the Habanero squirts. |
Tipping in the US. | Where do you live at? I've been living in Europe for the past year and one of the biggest thing's i've noticed in many places is that people don't tip. Because of this the service anywhere is absolutely terrible, especially in the Netherlands. I wouldn't mind paying a 10% for my server to come to me every 10 minutes an... |
Why do people become more religious as they get older? | There are really two potentially-compelling narratives that could explain the phenomenon: -- The older you are the more likely you are to be contemplating your own mortality. -or- -- Younger generations are increasingly less likely to be religious because religion doesn't play as central a role in their lives. Of these... |
What keeps other countries from "bringing the war" to US soil? | The only countries large and wealthy enough to attack the US are stable enough to understand that fucking with the largest military budget in the world is idiotic. There are ways to combat the US that don't involve swift and painful retaliation. |
How is it that approaching rain has a smell? What is it that we're smelling an hour before a storm arrives? | There's a good article on this subject over at the straight dope. _URL_2_ I'm on mobile, otherwise I would have pasted a quote and linked better. Hope it helps.Rain knocks down ozone from higher in the sky. What you are smelling is what it smells like at much higher altitudesPetrichor - the scent of rain. _URL_3_ "Petr... |
How does a person that never drinks untreated water not become ill after swimming in a lake or ocean? | Source protection is one of the key tenants of drinking water protection, so great lengths are gone to ensure fresh bodies of water are relatively safe. Couple that with the fact that major sources of bacteria is heavily regulated and you get * relatively* clean water that we can swim in. Also the only real issue with:... |
How come people might stutter when they talk, but you don't stutter when you sing a song? | When you sing a song it's from memory, you're repeating something you've probably gone over hundreds of times, I. Your head at least. Plus in most situations where a person will sing, the aren't under pressure. Whereas when someone talks it's impromptu, you haven't rehearsed, and there's more pressure on you.For me per... |
how the reddit frontpage is determined | It depends on whether it appeals to the hivemind or not. Intelligent, insightful links are ignored, whilst pictures of cats, a negative news article about the republicans, and a single image of a video game from the 90's amass thousands of upvotes. |
Why the LAPD cooperated so much with OJ during his chase? | Along with the points above, it's important to recognize that this happened only a few years after the massive riots after the Rodney King trial. The police didn't want to be blamed for the suicide of OJ Simpson, so they played it safe. At the time OJ was really the only one in danger so long as they could control the ... |
Why do military and police forces often side with the corrupt governments when the people rise up against oppression? | it's where the money comes from, and who controls the jails. plus it's their job to obey the law and lawmakers, and to enforce it. so when there's civil unrest, they're automatically on the wrong side from the outset. then the rioters tend to threaten the 'normal' people they're there to protect, and all their colleagu... |
Why do foods that are bad for you taste better than things that are healthy? | Our bodies were set up thinking we were going to have a problem getting enough fat and calories to survive, and it craves and hoards that stuff like nobody's business. On the other hand, edible plants are abundant in the wild, so we really didn't need to worry about most of our vitamin/mineral needs. Now, with plentifu... |
How does a company such as hooters get away with hiring only large-breasted waitresses? How is this not an ongoing discrimination lawsuit? | I don't know what Hooters you've been to lately but the hooters I've been to in Louisiana, Alabama, and North Carolina definitely DONT hire women with big boobs only. Id say most are average, if that with some being over weight even I dated a girl last year with B cups who worked at Hooters. It's amazing what the right... |
What exactly do courtroom artists do, and why are they a part of some trials? | Like a lot of things in legal proceedings, it's tradition. Back in the days before tv or even before photographs, a courtroom artist was used so that portions of a high profile trial could be disseminated to the public. These sketches would often be printed in newspapers next to a story outlining the current state of t... |
Why Aren't Third Party Candidates Allowed to Debate? | In what context are you referring to? If you're talking about the current US election campaign, the debates happening now are for the primaries.

Is there any merit to the idea that exposing yourself to germs strengthens your immune system? | Mice bred and raised in a sterile environment have much weaker, sometimes nonexistent immune systems.

Why do people tends to shift to the right (ie - adopt more conservative views) as they age? | It seems like the older a person gets the more averse they are to new things. Liberal policies generally focus on changing something where as conservative policies generally maintain the status quo.

How much effect does Central Park have on New York City's air quality? | Depends on which bit of air quality you care about. PM2.5 and Ozone for example are pretty regional contaminants. They are roughly the same street to street, area to area. They won't change too much in a large park. Ultrafine particles and things like NOx are very local. A large park could have a drastic difference in ... |
What makes PewDiePie so popular? | 1. YouTube monetizes channels by how long viewers watch and how many videos in a row they watch. So a game play through broken up into 10 minute intervals ranks high on YouTube standards. 2. Felix is considered international by YouTube so he's shown to more countries than if he was just in the US. 3. He knows what his ... |

Does exercise and eating healthy "unclog" our arteries? Or do our arteries build up plaque permanently? | The amount of cholesterol you have is more dependent on genetics than what you eat. If a direct family member had a heart attack at a young age then you would be at risk even if you ate healthy all your life. Although you do have a bit of control over your blood pressure but I'm not sure if a healthy diet would reverse... |
How are phobias acquired? | This is more psychology than biology. A lot of it corresponds to what we saw when we were very, very young. It normally relates to seeing something frighten our mother. If she is frightened by a spider, we 'learn,' in a way, that spiders are frightening. They pose a threat to our mother, so they pose a threat to us. It... |
Why is it worthwhile to separate colors from whites in laundry? | /r/nostupidquestions is better suited for this. I personally don't bother separating them. But most of my whites are socks or work shirts so they don't really matter to me. |
Why wouldn't game developers make exact copies of good old games but with better graphics? | Sometimes they do; I recently finished playing the remakes of the original Monkey Island games, with all the same gameplay but improved graphics and sound. But with the developers' commentary turned on they mentioned how much of a pain it was to re-port certain animations and whatnot for the modern version. So I'd imag... |
Why are springy doorstops made with maximum compression? Wouldn't they be more effective if they could be compressed to cushion the door's impact? | I would think there are three reasons for this mechanism. 1. You wouldn't want the spring to compress and then uncompressed to push the door back, instead you are just looking to absorb the force. This is accomplished with the rubber end on the door stopper. It absorbs enough force without swinging the door back at you... |
If steroids were around since the 1930's how do we know older players didn't use them? | The incentive wasn't there at all. The reason we have roided up freaks of nature now is because you can make more than some small countries with a good contract. You know how much Babe Ruth made in modern dollars? $80,000. The league minimum for the MLB today is $507,000. Babe Ruth, quite possibly the most famous baseb... |
why did some men have misstresses in the past but now the term isn't used much? | World War II happened.

Why is the filming and distribution of pornography legal, while prostitution is illegal? | The difference is both the male and the female are paid to have sex. They are selling a video of sex.

Why is it that when you drink water your pee become clear and thats a sign that you're hydrated, but when you drink beer you become dehydrated but your pee is still clear? | Beer has a lot of water, but your body has to process all that alcohol still.

Why is marriage "hard work"? | Because you've committed to live the rest of your life with another human being, and nobody is perfect. You're sharing each other's joys as well as struggles, and everyone deals with stuff different ways. You'll need to work through anger, frustration, jealousy and just never give up. There's going to be a lot of compr... |
Why don't clubs have a 'house set' of high quality drums so bands don't need to carry their own space mongering set? | I've thought about this too, it's probably because club owners / managers aren't musicians and don't see it as their problem. Also, I think most musicians are particular about their instruments. |
How do we know that conservation of energy is a law? How have we proved that energy cannot be created or destroyed? | The conservation of energy, in addition to the other conservation laws, are *laws* entirely because they've never been shown to be explicitly incorrect, although there is some wiggle room with things like relativity and the transformation of matter into energy and vice versa. |
Could I get a credit card and buy cheap items 1-3 times a month to build credit? | It also helps if you can get your credit line increased. Usually after a few months of paying your bill on time, if you call they'll be willing to increase it. It will probably start very low if you don't have great credit.Yes.

Why are chiropractors so controversial? | Because it's never passed actual scientific tests in regards to its claims.

What's the difference between grey and gray? When should I use which? I've wondered for years. | i'm always messing up sasha's name with these 2 variations", 'They are really just different spellings of the same word: "gr**a**y" is typically used in American english, while "gr**e**y" is associated more with British english . So it just depends on what audience you're writing for, and your personal preferenceI'm an... |
Why does China defend North Korea so often at the international level? | As I understand it, the main reason China backs up North Korea is because they want a buffer state. They are fairly paranoid and would rather have Crazy North Korea protecting them than nothing at all. Although lately China has become more and more irritated with North Korea's actions, I wouldn't be surprised if they d... |
Tax brackets and how it affects tax returns | Your co-worker didn't give you great advice, jumping into the next tax bracket will only change your tax rate for income above the cutoff.

How did people in the Stone Age deal with diseases (viruses, bacteria, parasites)? | They didn't for the most part. They just died.

The Watergate scandal and why it brought down a president. | Taping the doors was mentioned. One of the reasons the burglars/CIA were caught was because hey taped horizontally so that the tape was visible on the side of the door.

Why would a drug dealer mix a powerful opioid and deadly drug (fentanyl) with heroin, rather than a weaker substance, knowing that it could negatively impact future business? | They want to replace/extend the expensive heroin with the inexpensive fentanyl. Since they're both opiates, most users won't notice much of a difference between a pure H and a cocktail. The problem is that F is so concentrated. It becomes difficult to measure accurately and mix evenly. It's very easy for somebody to ge... |
How do neurons "know" things? As in, "this memory is stored in this neuron." | There's a great documentary about Eric Kandel's work around on the internet. In search of memory.

If sand is eroded rock, why does melting rock give you lava, but melting sand give you glass. | Have you seen molten glass? It looks like lava what's different as it cools is the composition and how it was cooled. If you take sand high in silica and melt it, you get like a lava substance if you throw in a whole bunch of other types of substances you won't get glass kapish? |
Why do ballpoint pens become unusable even though their see-through cartridges are shown with full ink? | A lot of times the ink dries up in the tip causing it to clog up.

It's likely that cartridge is damaged or faulty so you'll likely get the ink to clog ... |
Why do mammals like humans and dogs tilt their heads when confused? | There's no for sure reason, however a popular theory is that you learn to tilt your head when trying to understand at a young age.

Why so much hate towards Russians? | As a Canadian, people I know didn't mind Russia that much. But the situation with Ukraine is touchy.

How did it come to be that the United States is mainly controlled by only 2 political parties? | Our political system is designed to handle two parties.

Our laws and systems were designed from the pull and tug between two force... |
How does a pill prescribed to you know exactly what to do in your body? | Simply put, it doesn't. Drugs work by plugging into certain *receptors* in the body, and if there's no receptors available for the drug to plug into, then it won't work.

Why are many manual laborers who spend 8 hours or more a day lifting, pushing, and pulling heavy objects not in incredible shape from doing so after many months or years? | Diet is one part. We tend to either eat too much junk, or often barely meet our calorie requirements. So either we get potbellies or are wiry little guys that look like we might blow away. I'm the latter. The other part is that manual labour doesn't have progressive over loading. In a gym when you can lift 150lbs, you ... |
Why do money-wiring services exist when you can just email money for free? | This may be too obvious, but wiring money came long before the internet. I know that I've had my cc and debit card info stolen using PayPal, eBay, etc. I now use visa gift cards online. My parents would wire money and never consider emailing it. The same is true about most people I know over 50. I'm 43. |
Why do we have two of some organs (e.g. lungs, kidneys, etc.) but not of others (e.g. liver, pancreas, etc.)? | I don't have a full answer for you, but I would like to point out that some people are born with only 1 kidney! :) |
Why exactly is it considered racist for white people to be proud of their heritage, but not any other race? | Because white people although a minority globally, have been owning shit world wide for a long time.

Everyone that bully beat up is still going to be pissed off and think the bully is weak now be... |
...If aliens put a satellite into earth orbit to observe us, would we even notice with all the other satellites up there? | Quite likely, yes--the space agencies of the world do their best to keep track of all satellites of earth, and in the long run a mysterious extra would be noticed and investigated if no explanation was apparent. If we're talking about interstellar travel, though, perhaps they could make a satellite too small to easily ... |
Why is it when a US service member dies on active duty the family receives at most $400k, but when young man is murdered by police and the family receives $5mil. | Everyone here seems to be comparing the willful and informed self-exposure of a member of the military to the danger associated with service to an unexpected death at the hands of the police. What their ignoring is the fact that the $5 million is an out-of-court settlement in response of what will obviously be a civil ... |
If Gandalf knew Bilbo has the ring, why did he let him keep it? | Gandalf suspected it was a ring of power, but did not confirm it until Frodo had it. Even then, Gandalf held one of the Three Rings of the elves , and whoever had the One Ring was likely to be influenced by it.

It's more like you get... |

Why can antidepressants increase suicidal thoughts? | To my knowledge, it's not that they *cause* suicidal thoughts, but rather allow them to occur more easily than without antidepressants. & nbsp; If someone had major depression with suicidal ideation, he might have too low of physical energy to commit suicide. Some antidepressants can lift the lethargy that often comes ... |
What is maximum dynamic pressure, or "max-q" in aerospace engineering? | As your rocket flies off, it gains velocity proportional to it's rocket engine power. As it gains velocity, it has to push thru air resistance. As it gains velocity, it also gains altitude. As you gain altitude, air density decreases proportionally. There comes a point where resistance vs velocity vs altitude reaches a... |
