why flies and other bugs love to land on people and fly around their heads? | They don’t have the cognizance/brains to understand the connection between flying around you, your hand, and its connection to you. Aka they’re too dumb to know you’re trying to swat them, they’re just trying to avoid a giant hand. Also they probably think you smell nice. Nice is subjective. Wasps like meat, flies like... |

A build ... |
What is going on in Turkey in regards to both the surrounding countries and the rest of the world? | They're opposed to Russia and Assad's regime in Syria. They're a member of NATO but their interests are not exactly aligned with the other members of the alliance. They've been slow to openly oppose ISIS because they are against Assad and the Kurds. There are signs that they have been directly or indirectly supporting ... |
Why were plants so big in prehistoric times but evolved to the size they are now? | Back in dinosaur times, there was a lot more carbon dioxide in the air . Plants literally make themselves out of the carbon in the air . As the atmosphere changed, there was less CO2, so there's less stuff to make plants out of.There was not as much biodiversity back then. Most species today were not around back then. ... |
How does Venezuela’s foreign currency regulations and price controls work | They are laws, and they are enforced like any other financial law. If you get caught making a transaction in violation of the law, you go to jail. The concept behind these laws is to isolate internal transactions from the global economy. This protects local transactions from the rapidly fluctuating currency, at the exp... |
What does popping joints (knuckles, toes, back, knees, neck ,etc.) really do to your body? | Supposedly not. Years back, a scientist popped the knuckles on his left hand every day and not his right, with no apparent injury or weakness. Source: _URL_0_ |
El Niño ... Or whatever is causing this crazy weather across the U.S. right now | In simple terms, every 5 years or so, intermittently, warm water from the equator in the pacific ocean makes it's way east to our west coast because of cycles in wind patterns. This causes hotter temperatures and more rain or snow . It's basically as simple as that. Historical records show it could last as long as a co... |
Why do chess tournaments segregate men and women? | It's not because people expect women not to be able to compete with men in terms of intellect, or vice versa. It's done because, as was indicated in the comic, chess has traditionally been a male-dominated activity, so the point of creating a women's only tournament makes it seem slightly more welcoming. Increasingly, ... |
How can some women not show signs of pregnancy until extremely late? | Genetics can play a part in it. Women who are overweight can miss the signs.

How our brain produces "pictures" such as when we are dreaming or remembering a past event | When you see things with your eyes, certain sets of neurons are activated in response to certain inputs from your eyes. For example, a particular set of cells activates when you see horizontal lines, another set activates when you see vertical lines, and other sets respond to color, depth, and texture. There are also w... |
Why are our lips red/pink? | I can't remember the exact article or reference, but I seem to remember something about how they are supposed to resemble vaginas and signal reproductive fertility. People's lips are usually thickest around their most fertile years. |
Why do Americans wash butts with TP while third world country wash butts with water and soap? Which method is cleaner? | I don't know about you, but I don't eat and interact with the world using my butt. Maybe, yes, if people shook butts as a social greeting, we would reconsider the sanitation of our methods. TP is a lot easier to use since most NA toilets are not equipped with a water spigot thats angled upwards. Plus it would mean havi... |
Why animals try and keep themselves awake, when they could easily just sleep. | Animals, though they are tired, might not want to sleep because they want to be prepared for danger. They want to stay alert because they need to protect their young, their humans, or themselves. |

This behav... |
How does the brain function ? | We don't know. We know that all the things the brain does arise from the staggering network of connections between nerve cells, communicating with each other with a few simple rules which, together, create the immensely complicated meat computer in your skull, but we don't yet have any idea how consciousness works. Tha... |
Who would be responsible for an accident caused by an autonomous car? | No laws have been decided on this front yet, so nobody can answer this question with certainty. It also might end up depending on what sort of defect caused the accident - is it the owner not keeping up to date on maintenance, is it a design flaw by the manufacturer, or was it something in the GPS that went wrong, etc ... |
How do planes fly upside-down if they generate lift from their wings? | Because the curve actually generates a small portion, often less than 5%, of the lift. Nearly all the lift is generated by the angle at which the wing hits the air. Even planes with completely symmetric wings fly just fine. _URL_0_The description that a wing need to be curved to provide lift is not true. You can show t... |
How come if I go to sleep really hungry, I wake up less hungry? | When you go without food for a little while, your brain says "hey, I'm receiving signals that the body needs food. We must be hungry." If you don't eat, then your brain says "Hmm I keep telling him to eat, but he's not eating. There must not be any food around." So your body starts fasting. That involves slowing your m... |
Why are all sub moderators locking their subs? How the hell does this help anyone? | It shows that they disapprove of the way they've been treated by the reddit administrators. Kind of like sit-ins during the civil right's movement. |
How come the file size of my camera's photo are always different even though the same amount of pixels are being recorded? | not an expert but this is what i would think. your camera captures and stores images using file compression. it is not storing raw data straight from the image sensor. if there are many pixels that contain similar data , the group of pixels can be compressed by storing the color/exposure data as a single pixel, then th... |
How human brains grow (from age 0 to 18)? | Some parts of the brain grow to receive signals from the senses, eyes etc. these are then interpreted and coordinated with other inputs. Some parts of the Brain make calculations about risks of particular actions, others respond to changes within the body and others to chemical inputs. Basically the growth and developm... |
How does the m & m factory draw an 'm' on every single m & m? | It's part of the manufacturing process and they have a specific machine for doing it: > The single-colored batches are combined into the mixtures of red, yellow, blue, green, brown, and orange. They are then transported to the machine that stamps the "m" on the shells. A special conveyor belt carries the pieces to this... |
What are the advantages of animals that lay eggs versus those who give live birth? | Many reptiles and insects that lay eggs can sort of "set it and forget it" meaning they lay the egg, walk away and let nature do its thing. This has the obvious benefit of not having to go through pregnancy and parenthood both of which are fairly stressful and dangerous periods for mammals. Live birth though means that... |
Why do so many religious extremists care about what other people are doing? | This phenomenon is not at all specific to religion. This happens all the time in politics, education and even science. In the context of religion, it is not limited to religious "extremists"--Atheists do it frequently as well. I 'd hardly call one family member trying to influence another an "extremist"--I would tend t... |
Why are Nazis referred to as "right-wing" when they were members of the National Socialist German Workers' Party? | They called themselves "socialist" because it was popular at the time, and *national* "socialist" to emphasize that they were opposed to the international socialist movement.The Nazis were socialist like the Democratic People's Republic of Korea is a democracy. You can name your party/country whatever you want, doesn't... |
How does the camouflage skin of Octopi, Squid, and Cuddlefish match their surrounding color and texture so accurately? | They have highly specialized cells that get a signal from the brain when it detects a certain surrounding colour and then expand or contract in order to change the pigment in the cells. You can notice that they’re never fully campouphlaged but only partly and being under water helps them become ‘invisible’. Due to lack... |
What exactly is funny about the bombardment of stupid/offensive/off topic comments from "le reddit armie" on many youtube videos? | They are not funny. It's just trolls doing what trolls do. They do it to get attention. If probably fills some void in their otherwise sad, empty lives I suppose. |
Why does science blame the proximity to the sun for our observation[s] of Neutrinos? | Perhaps you are aware of [Olbers' paradox]. This covers it quite nicely, just substitute light for neutrinos. Here is the ELI5 though. Space is expanding. Far away events become less apparent. Furthermore neutrino flux vs distance from the source follows the inverse square relationship. The further away you get the low... |
Why do many rivers never seem to dry up? | The soil soaks up water, and this water is released slowly over longer periods of time, like a trickling sponge. In places where the soil does not retain water as well, rivers are mostly seasonal, and only appear during rainy season.Most rivers are are effluent streams, which means that they actually get their water fr... |
How is "Hollywood Accounting" legal? | Is there a news story or example you are thinking of? Tax Evasion and "Cooking the Books" are heavily heavily prosecuted. Heck they took down *Al Capone* on Tax Evasion. |
What is a trick-taking game? | A game like whist or bridge where you have to play a round of cards, each person taking turn, and one person wins the trick. Then you take turns again for the next trick. |
Why lithium-ion batteries keep catching fire | Lithium ion batteries use the movement of lithium ions from one side of the battery to the other, divided by a separator in the electrolyte that allows the lithium ions to pass through, but not the cathode or anode chemicals. If that separator gets damaged, it causes a short-circuit where the ions pass through a hole i... |
Why are photographers famous? Aren't the camera and post-production artist doing the work? | A lot of the challenge in portrait photography involves posing the subjects in their environment, getting the right emotional reaction out of them, getting the lighting right to emphasize the right things, and timing.The composition of an image can evoke a visceral emotion if done correctly. If you look at some iconic ... |
Why do you feel the pyrotechnics heat from long distances at a music concert? | Visible light and infrared radiation transmit heat to you via electromagnetic radiation. It passes through air harmlessly until it hits something it can absorbYou know how when the sun comes out, you instantly feel the heat on your skin? This and the heat from pyrotechnics are both infrared radiation. |
How much is still undiscovered in the field of physics since almost all the fundamentals we know were discovered before the cold war era ? | There have been plenty of new discoveries and hypotheses since. It's just that they're so arcane and impenetrable that the average news outlet and layperson's explanation tends to stick to the Soviet-era stuff. The cutting edge in terms of hypotheses, mathematics and ideas - the cerebral side of science - has ALWAYS be... |
Why sleeping makes bad breath? | When you're awake, you're drinking stuff, you're swallowing, your mouth is opening and closing, and your tongue is moving, so bacteria doesn't get a chance to fester. When you're asleep, your mouth is closed for an extended period of time. It's nice, warm and damp and there's nothing stopping the bacteria from cozying ... |
When the army is called in to handle violent protests, etc why do these men agree to shoot upon their own fellow citizens? What happens if you refuse? | Because most of the time, the army isn't called to stop a protest unless it has become a full fledged riot. And rioters are not exerting their right to protest anymore, they have just become a danger to themselves and others and to private and public property, and must be dealt with as such. In the case of peaceful pro... |
How can your eye focus so closely when using video display glasses? | Basically, most of the ones that people like cheat by using lenses in the display to trick the eyes into focusing *as if* the display was much farther away. I don't remember the exact number, but the distance away that an object has to be before it looks like it's "infinitely far away" is staggeringly short. Like, from... |
when there's a cluster of bug bites on my body, is that because that spot was especially tasty or the bug couldn't get a good tap? | Most likely you brushed up against something with bugs on it and more than 1 jumped on you and bit you. I.E. if you step in an anthill you are going to get a cluster of bug bites on your foot because it came into contact and they can't jump far. It could also be a 'bad tap' but bugs are pretty efficient at 'tapping' an... |
Difference between Risk Tolerance and Risk Appetite | Risk appetite is a broad description of acceptable risk, while Risk tolerance is more to the point. An example: say for a holding; the RA would be what the group deems acceptable whilst chasing their goals, while the RT actually makes this measurable for its companies and ties it to KPIs. Hope this helps! |
Why does campfire (or bbq pit) smoke always change to blow right at my head when I'm the only person around the fire? | This is likely a combination of confirmation bias and availability heuristic. Or more simply the belief that the smoke changes direction to you every time you move to avoid it because the smoke changing to you is the more memorable event . The availablememory then leads to the belief that this always happens. Now when ... |
Cores in a graphics card. Why/how does the number of cores matter? | In simple terms, each core allows the processor to make one calculation / operation at any given moment in time. So, even if you have a really high performance single-core processor that can perform billions of operations per second, the fact remains that it can only process one single operation at a given time and ope... |
How do bot-flies managed to land on a human fast enough to lay an egg that grows into a larvae inside the human? | They are already laid, and stuck to the body of the fly. When the fly zooms in it attaches the eggs to some hair, it doesn't have to sit around trying to lay the egg right then and there. |
Why do most energy drinks make me feel sick and jittery, but coffee doesn't? | Sick: the sugar. Jittery: probably a mixture of caffeine and sugar. Look at how much caffeine is in your energy drink, then multiple that number by how many servings there are. There is about 120mg of caffeine in a cup of coffee for you to compare to. |
How could people go to remote islands which are located thousands of kilometers away from the coast thousands years ago? | By boat. The islands were mostly discovered by accident, and it could take a *long* time for an island to be discovered. For example, Hawaii was not settled until around 500 CE, and New Zealand wasn't settled until the 1400s- only three centuries before the British showed up. And Madagascar, despite being quite close t... |
Why is the US concentrated on eliminating ISIS when there's drug cartels right in their back yard (Mexico) that kill more Americans annually than ISIS? | I'm going to say that ISIS's stated intent is to destroy America. Mexican drug cartels are really just interested in making money. Americans are their customers. The murders are more like collateral damage, or a cost of doing business, not a deliberate effort to kill Americans for the sake of killing Americans. In othe... |
How/why do windows and doors not cave in under the pressure/weight of the water from a flood? | Because often by the time the flood waters reach high enough to put sufficient pressure on the door or window, water has leaked into the house from other gaps, like the walls, subfloor, etc that the water pressure on both sides is equal. In that picture, that window might be thicker/stronger, and able to better resist ... |
Why do foreign languages seem so much quicker then English? | Interesting question! This is in large part due to the data density of the average syllable in a language. Languages where each syllable carries a lot of information are spoken more slowly than languages with less information density. So Spanish is generally spoken faster than English because each syllable in English c... |
Why is it that a 10 minute 720p video I record with my phone is 700mb, yet a 720p 1.5 hour long movie uses less data? | Before movies are distributed, the data gets carefully compressed on full-sized computers that may have spent many minutes or even hours compressing it, after the recording was complete. The result is better compression, hence a smaller total file size. |
Can not sleeping enough kill my confidence? If so, what's happens chemically in my body for that to happen? | I'm going to say not really, to your first question. What probably happens more of, is that your lack of sleep results in poorer cognitive capacity, attention span, motor coordination and the like, making you suck more at whatever you are trying to do. In turn, the poor performance you witness yourself doing impacts yo... |
What exactly makes something addictive? | Drugs such as meth and cocaine release a HUGE amount of dopamine into the brain. Dopamine makes you feel good. The pleasure receptors in the brain start to crave this and therefore you start craving drugs. Thats pretty much what makes drugs, food, sex, porn, or just about anything pleasurable addictive. I'm no expert b... |
Leasing or purchasing a vehicle, what circumstances would make one option better than the other? | The moment you buy a car, the value drops. Every hour it becomes worth less money, every mile you put on it, it becomes worth less money. So the idea is if you lease it, you 100% know what you are getting and what you are paying for it. If you lease a car for 36 months @ 300/mo with one time payment of 5,000 and up to ... |
What really happens to all my trash when the garbage man takes it away? | It depends on where you live. I'm presuming your "trash" and "recyclables" are separated, so I'll just address the "trash" side. Garbage is collected in trucks on a regular schedule. It's compacted and stored in the truck, before being dumped at a landfill, typically. Some places still burn their trash . Some places ta... |
What is happening when we have our "morning voice"? | Imagine your vocal cords like a rubber band. When you twang a stretched rubber band, it makes a twangy sound. If you stretch the rubber band tighter, the twangy sound but higher pitched. In the mornings, your vocal cords are relaxed, so they are looser and aren't as stretched. So morning voice is lower. I'm not too sur... |
How come so many comments on default subreddits are being deleted these days? Isn't the downvote button for stupid comments? | When people start bashing you for something and writing mean things then you don't want more of it and simply delete the comment. Or they are afraid to lose their precious karma. |
Why do you get that weird saliva when you're about to vomit? | Vomit is very acidic, so your body prepares by releasing extra saliva to protect the inside of your mouth. The saliva dilutes the acid and even neutralizes some of it since it is alkaline. |
Why reddit "fuzzes" the ratio of up/downvotes | Not merely anti-advertising, but anti-spam. Reddit is constantly inundated with spam links being submitted by bots - that is, automated programs. Plus bots exist to go in an upvote those links. These bots can be detected and banned. However, if they were simply blocked outright, the creators of those bots would know th... |
Why do newscasters/show hosts sometimes use the same phrases verbatim? | In the case of that video, there are news services which the staff of these programs subscribe to which provide resources and even scripts on how to present stories. These are inexpensive and designed to fill gaps in programming. All of the subscribers get several of these each day or week and gets people off the hook ... |
What changes will you notice if you go from drinking a very small amount of water every day, to drinking the suggested amount? | Your urine should become clearer and stink less. The feeling of dryness of your eyes and lips should start to go away. Less immediate is a decrease in headaches and muscle fatigue. You are going to start peeing more, maybe one or two extra trips to the bathroom a day depending on how dehydrated you were. Being hydrated... |
why do companies that have monopolies advertise? | They aren't advertising to say their product is better. They are advertising to say "hey come buy our product" |
why do advertisers pay so much for ads, as they probably won't make the money back | Your premise is wrong, they do make it backThey spread awareness of their products via advertising. And yes they do make a lot of money through advertising otherwise nobody will be making adverts.Some big companies will have HUGE advertising budgets like Coca Cola and John lewis who have HUGE christmas advertising camp... |
Can DNA be used as an acid? | Yes, DNA does neutralize basic solutions to make DNA salts. As for things other acids do, acids have different uses and they don't really do the same thing all the time. There are probably some things DNA would do, but not the same things as sulfuric acid for example. |
The difference between imagination and creativity. | I have an active imagination, I can see characters described in a book, I can easily suspend disbelief when watching a film. I can imagine complex things, and visualise how they will look. Creativity is turning the above into reality, which on a small scale I can, but artists and engineers thrive on this process as do ... |
Why is snow almost a solid white, while other frozen forms of water are clear? | Snow is a whole bunch of individual ice crystals arranged together. When a light photon enters a layer of snow, it goes through an ice crystal on the top, which changes its direction slightly and sends it on to a new ice crystal, which does the same thing. Basically, all the crystals bounce the light all around so that... |
Why is charcoal black and ash gray? | Charcoal still has all its carbon in it which gives it a dark color, ash has no carbon left thus the gray or white colorCharcoal is formed by incomplete combustion, they make it basically by burning wood without enough oxygen. What you’re left with is carbon rich. Ash is completely combusted, and is so carbon poor. |
Why do people who drive Jeeps always wave at other people who drive Jeeps when they see each other out driving? | Some vehicles have an identity attached to them. You drive a Jeep because you're 'a Jeep person' not because it's an economical choice. Cars with identities like that tend to have drivers who think they share some sort of camaraderie with other drivers of that car. It happens with performance cars too.Same reason corve... |
Why is there a different kind of helmet for every sport? | All of these sports have different common injuries and ways in which one can become injured. Different ways of falling, at different angles. One can anticipate where somebody could receive an injury on their head dependent upon their current sport. So yes, some helmets have more padding in different areas, are differen... |
Why do body parts get that sudden shocking feeling after hitting it on something. | I would imagine it's a combo of shocking the local nervous system along with a return of blood flow after being forced out of that local body part. Much like the pins & needles feeling you get in a limb with limited circulation. |
What would happen if my belly button broke open? | What do you mean "broke open"? Do you mean an internal force pushing at the belly button until the flesh ruptures? Do you mean a sutured area giving under too much pressure? Please be more clear, because it depends on the method with which it "breaks" as to what would happen. |
why do houses appreciate in value | A house goes up in value for a few reasons. One of the biggest reasons is the increase in population, another important reason is inflation. The usefulness of a house never really goes away. The land is always a piece of land that can be used. A crappy house can be rebuilt at anytime. When a car gets old, you can't rea... |
What determines the shape of a cloud? | Wind sheer, humidity, temperature, atmospheric pressures, storm systems near by, pollution levels, convection, the jet stream, and altitude. Amount other things. Its why no two clouds seem to ever be identical. |
Why do our Hair and Finger/Toe Nails constantly grow? | Hair and nails are made of dead cells. They're essentially waste products. The only way they'll stop growing is if you die, because your body is constantly generating waste. Hair is useful because it helps regulate temperature, and nails are useful for handling things. They can sometimes be hazardous, but the only dang... |
Why can't we start re-pumping the heart once it is stopped? | The heart pumps blood which gives cells oxygen. Cells need oxygen to make energy, and most need energy to do what they do. Without energy for too long, they die. So obviously, if the heart stops, after a couple of minutes, all the cells start dying. Once the cells are dead, even if you restart the heart, but it'll just... |
Why does Arizona state primary election results not fit any polling data anywhere? | There was a professional poller on CSPAN the other day. He said no matter how large the poll is, no matter how many people you get responses from, the polls do not represent most of the population. The reason is: 95% of the population WILL NOT TAKE A POLL. He said he 'd been trying his entire life to get "Did not respo... |
What is Abstract Art? | Art that isn't trying to LOOK like something, but maybe is trying to make you FEEL something. Sometimes it's an artistic version of a real thing that isn't how it looks in real life but highlights what the artist sees as the most important parts. Sometimes it's a picture or sculpture that is supposed to represent an id... |
What keeps our blood warm? | Traveling through tissues which are warm. Blood itself doesn't consume lot of energy; red blood cells are pretty simple and have a simplified metabolism. |
How VW used software to cheat on emissions testing? | Car engines are getting smart. They're controlled by sophisticated computers that can be used to analyze engine performance and ensure the engine is operating smoothly and correctly. The VW engine took advantage of this by building in the ability to detect when it's being measured for emissions, and modify the engine t... |
Why science and technology news articles never link directly to the research papers they describe | I'm by no reasons a science journalist, but I can think of two reasons off the top of my head: 1.) Often times, the study in question isn't quite finalized or published yet. In that case, the journalist is dealing with abstracts/press releases/unofficial copies. The actual, official paper doesn't yet exist. 2.) These p... |
Why are white hairs a different texture and frizzier than normal hairs? | Hair is made up of 3 layers 1) cuticle later - clear, determines the sheen of the hair, very thin layer think of it almost like fish scales. If your hair is damaged the cuticle layer is blown wide open and your hair looks "fried" 2) cortex - determines color of hair, thickest layer, also has a lot to do with thickness/... |
Why can we see bacteria in a petri dish but not on ordinary surfaces? | Petri dishes aren't just a clean piece of glass, they have [agar in them] - a clear, gelatinous substance full of food & nutrients for the bacteria to grow on. Since the agar starts sterile, you also don't have to worry much about other microorganisms competing with your sample & killing them off. It's basically the id... |
Why does very hot water feel confusingly cold? | We have separate sensors in our skin for sensing hot and cold temperatures . These sensors will get activated at specific temperature ranges and the activation of these separate receptors is how your brain knows if what you're feeling is hot or cold. However, there are certain cold receptors that also get activated whe... |
What are the "brushes" on the side of escalators actually for? | According to the [Otis Elevator Company] those are safety brushes used to protect passengers. > > > Mounted on escalator skirt panels,Otis’ staggered, double-row nylonbristles extend from the escalatorsides. Passengers who stand tooclose to the skirt will feel the bristlesand instinctively move awayfrom the sides, maki... |
On fixed-wing aircraft, the pilot sits in the left seat, but on helicopters, they sit in the right seat. Why is it different? | On the first helicopters, the work required to keep the cyclic control in position was high. That meant it needed to be in the right hand. The collective control and throttle thus had to be for the left hand, and putting that in the middle of the helicopter reduced weight. It also meant that radios and other stuff that... |
How is money transferred digitally from bank to bank? | There is a special network, called SWIFTnet, that connects the banks. The Society for Worldwide Interbank Financial Telecommunication uses a standard protocol to identify each bank and transmit encrypted payment orders. Each bank is part of a collective that reconciles these orders each day. So if you spend $100 on som... |
If one wants to see a therapist to work through some bad things they've done that might land them in jail, without being reported, how can this be done? | Have the things you've done caused harm to yourself or others or do you plan to cause harm?

When a surgery is very long (12 hours or so) how do the surgeons and nurses rotate, and update each other on what has been done or what needs to be done? | My relative had 13 hour heart surgery at UMich hospital and the same two physicians were present during the entire procedure. When they met with us they looked very tired yet they took time to explain the results. My relative is much improved. Not sure if the nursing staff stayed from 6am to after 7pm but the main phys... |
why does spicy food like peppers burn the tongue, but spicy stuff like wasabi burn the nasal passages instead? | Different kind of "spice" basically, the peppers have capsaicin while horseradish enzymes irritate the eyes and sinuses. Wasabi is in the horseradish family. |
Why fog seems to clear as I move through it | Imagine you are walking through a forest. When there aren't many trees, chances are you can see really far before a tree gets in the way and blocks your vision. If you go into a denser part of the forest, you can't see as far anymore, because there is a higher chance that there is a tree in the way. However, you can st... |
If a baby was born deaf. How and/or what language will the baby develop in the mind that is responsible for thinking and processing information? | That's actually something that makes learning how to read very hard for deaf people. They've learned sign language from birth and they basically think in sign language, but when it comes to learning how to read, you have to understand two things: first thing is that sign language is an actual language with its own stru... |
Why do we have to have our wisdom teeth taken out? | You don't have to have your wisdom teeth taken out and many people don't. Others have to have them taken out because they grow through in odd angles, or painfully, or impact on the teeth around them. A number of people also have them out before having braces to avoid altering the shape of their jaw/tooth arrangement if... |
Why are External Network Hard Drives so expensive and why is iCloud so much more popular? | Just a comment for those worried about catastrophic loss of data- burglary, fire, tornado.
