Is it possible to use currency exchanges like the stock market and "buy low, sell high?" | Go to _URL_0_ to see current worldwide exchange rates. I believe they now do trading from that site as well. The best you can do is to press your luck with economies that are getting sanctioned. Iran, for example. A few years ago, when all of the countries started putting financial strain on Iran for its nuclear someth... |
Why does America win so many medals at every Olympic Games? | We are the 3^rd largest country in the world, 5x as many people as the U.K., more people means more athletes. As for why China/India don't dominate, that's due to cultural differences.Because they spend a lot of money on sports programs at every level, compared to other countries. This is also only true for the Summer ... |
Why don't car companies put better technology in their cars? | The gadgetry in cars will be outdated far quicker than the car itself. Take a car from 2007 which would be considered fairly recent - Tablets as we know them today didn't exist back then, modern smartphones were only just breaking onto the market too |
Why don't we have zero calorie alcohol? | Alcohol itself has calories. You can even live off nothing but malt liqour, for a little while, because you won't starve to death since you're meeting calorie requirements. You will run into nutrient deficiencies, though. You can certainly remove sugar from alcoholic beverages, vodka will contain almost nothing else ex... |
How did teaching going from being a highly respected position to a low-paying, mediocre job? | IMO it is because of a cultural shift; there are so many success stories about high-school dropouts becoming millionaires and, conversely, about how many college graduates are stuck living in their mom's basements - society starts to value education less and therefore pay less for it. Also teaching is a profession that... |
Why does Japan have awesome candy? | Japan is huge on novelty and seasonal/limited/local editions of things. It's not only candy, it's beer, menu items at restaurants, special TV events, what have you. What this means is that over the course of a year you see a million versions of typically mundane things. A post about the 500 types of Kit Kat available i... |
How is it that people who are paralysed from the neck down still have a beating heart? | And this is why I love this sub, I get answers to questions I hadn't even thought of. What an amazing organ the heart is. |
Why is it that when you point a flash light up towards the ceiling, it creates more light? | It doesn't. From my engineering knowledge it doesn't. Your question has many variables but I'll try to break it down. First let's talk about how close you are to the source. Pretend a showerhead is a lightbulb. The water is stronger near the showerhead right? Same for light, it has more energy near the bulb, the differ... |
Why the hell do they call 3840 x 2160 resolution, 4K? Shouldn't it be 2K? | You don't have 4k, OP. You have what is known in the industry as Ultra HD . 4K is actually 4096 x 2160 and that resolution is also UHD. 480i - Standard TV 480p - Enhanced TV 720p/1080i/1080p - High Definition Television 1080p is also commonly put into another category - Full HD 2130p/4320p/8640p - Ultra High Definition... |
Is " & " only used for stylistic purposes? Are there any times I should be using " & " instead of "and?" | As other redditors have stated its use in formal writing, I'll chime in. Learning to do it quickly in one stroke can save time when taking notes, using shorthand or jotting things down. It's a formal nightmare, but if learned, an informal dream.Semi-related: The China Miéville novel *Railsea* uses ampersands in every p... |
why the US uses a month/day/year format for writing the date. | Personally, I prefer YEAR/MONTH/DAY, where April 1st, 1980 would be 1980/04/01. I'm pretty sure this comes from using computers. Files and folder names sort in chronological order this way.It's easier to say less words. You could say "*The* first *of* January, 2012" or you can just say "January first, 2012." Also the s... |
Why do motorcyclists rev their engines at stops? | I do it because I'm bored. source: I have a fuel-injected bike with stock exhaust.Dirt biker here. Out of anything else I would say force of habit.As somebody who jpe gam to ride in the past couple of years I have to say that I don't. But I imagine it's more of a habit for people who have been riding for a long time. A... |
Why do humans have such a large lifespan when compared with other mammals of similar mass? | I don't know that size really has much to do with it. There's species of turtles and tortoises that, while smaller than us, will live over a hundred years, sometimes even 200 years. And many cetaceans especially orcas will live to their 90s, and they're much bigger than humans. |
Why would places like Rosland Capital want to sell their Precious metals if they are "about to skyrocket in value" | Because they've bought up a bunch of gold and silver, so now they need a bunch of people to start buying it too so that it'll increase in value. They accomplish that by making people believe it's about to increase in value", '> Why would they want to sell these things off if that were true? Because you can't take gold ... |
How do brains of compulsive liars work? | Borderline personality disorder is a brain malformation or dysfunction where a person lies to get ahead and have little self awareness. Sociopaths and psychopaths are certainly suffering from this. In that sense, it's a physical issue. Not sure if that's what you mean.Can be a symptom of Antisocial personality disorder... |
why do we assume extra terrestrial life needs carbon and /or water to live? | There's an important point that a lot of people seem to have missed. It's not simply the fact that carbon is more abundant than silicon, it's also the fact that due to the details of the chemistry of carbon , it is much more capable of forming very complex, dynamic structures than silicon. Carbon and silicon behave sim... |
Why do so many mansions have more baths than there are beds? What is the point? | When you're talking about traditional mansions - mansions are designed to entertain guests regularly, and the bedrooms are often on the second or third floor. The first floor will often also have one or two nicely-apportioned half bathes with a toilet and sink, and also a servant's bathroom near their area. You also ha... |
On a console gaming system with unchanging hardware like the Xbox 360, which has been out since 2005, how do the graphics on games keep getting better? | The hardware is the same, but software using it has become more optimized to run on it with time. Your OS updates aren't just for show |
Why do brakes on cars seem to work better temporarily after it rains? | So 'better' was a poor choice of words, apologies for that. What I meant is, after it rains , I've noticed I don't have to apply as much pressure to my brakes, and when I apply the pressure that I would normally during dry conditions, the truck halts much faster, to the point where I am thrown forward . I've always fou... |
Why do dogs hump things that are not dogs? | My female dog loves to hump my boyfriend whenever she gets the chance. I've looked it up before and apparently it's to show dominance over another. So she's like 'I'm the alpha here not you asshole'. Then again she could just be a horny little thing.Can human men tell that a fleshlight is not a human female? |
Why, when closing your eyes on a train, can you convince yourself you're traveling in another direction? (backwards or forwards) | You are in what's called a static frame of reference. If you close the curtains, and the rails were perfectly even, there would be no stimulus to indicate that you were moving at all, and no test that you could perform - unless it measured phenomenon outside the train car - would ever be able to tell you any different. |
Why does Microsoft Word use Calibri as the default font when most papers require Times New Roman? | I suspect that users writing academic papers are a fairly small share of Microsoft Word's user base. You could easily find a template that defaults to the correct font and other settings that you need for your papers. |
what is the difference between type 1 and type 2 diabetes? | Check out the discussion going on here right now, especially the top comment: _URL_0_ TL;DR: Type 1 is autoimmune, where the body destroys the cells of the pancreas that create insulin. Your nephew will need to take injections or use and insulin pump to give him insulin and keep him alive, until/unless a cure is found.... |
isn't everything biodegradable, eventually? | If you're asking *can* all matter be bio-degradable, then it's theoretically possible. If you're asking *will* all mater be bio-degradable, then the answer is *we don't know.* It would require new micro-organisms that aren't known to exist to bio-degrade things we currently consider non-bio-degradable. |
How much profit porn sites make and how? | Many of the smaller sites are still fairly profitable with a bit of luck, though there's a lot sites crowding the market. Instead of investing the money into content, tube sites can spend it elsewhere. Some of the larger sites pay smaller tube sites to embed their videos. Both earn from ads within the video player. Oth... |
How are train engines strong enough to pull that much weight? | Huge, powerful engines and low friction. A locomotive engine is about the size of a delivery van, and some trains have a dozen of them. On top of that, steel wheels on steel track have very low rolling friction. Car tires have to be stickier to prevent side to side motion, the crown of the track makes that less of a fa... |
How do woman's periods sync up? | They don't. It's a pretty common myth, and a lot of people still believe it, but it isn't true. It's just a coincidence that people tend to notice, especially since periods can last up to 7 days. Two women with 1 overlapping day cover nearly half the month, so add 1-2 more women in to the equation and it's nearly certa... |
Why don't I get an infection when I shit so hard that I bleed? Serious question. | Haven't done much biology in years but often the answer is that your body's blood vessels operate under huge pressures. The blood coming out basically means that the bacteria isn't going in. As a result to get an infection you would have to force the poo into your bloodstream. |
Why are Beatles songs broken up when you listen through one headphone? | It mainly had to do with the recording equipment available at the time. You'll notice that their later albums didn't really have much of that issue. The last album they recorded, Abbey Road, used a 16 track recorder. That meant that they could manipulate 16 tapes running at the same time; so when they were making a mix... |
Why did humans evolve to lose most of the hair that our early ancestors had, yet require clothes to stay warm? | Early ancestors and modern monkeys, apes and all that lot have longer hair folicles where as humans have shorter hair folicles and more hair. This creates the effect that monkeys and whatnot have more hair than us. In other words we haven't lost it, it's just gotten much shorter making it look like we have less. *Edit:... |
What exactly happened with Kevin Spacey? | He asked a young boy if he could touch his pee pee. Boy was underage. Boy didn't want him to touch his pee pee. |
How would life have started on a planet that none exists? | To put this in perspective you need to understand the basic chemical mechanics of organic life forms. They all consist of these proteins called amino acids. The chemical makeup of these acids arent that cool, but when doing organic processes they work amazingly. What happened way back then is a ton of radiation was zap... |
Why do people buy used police cars? | You can usually buy one from the auction [like this dealer does] with brand new performance tires on them worth more than the car. The police cover their asses and sell them with new rubber. Also, the maintenance schedules were adhered to religiously. I've owned several that went beyond 600,000 miles with no major repa... |
What is the point of courtroom sketch artists? | Some courtrooms don't allow cameras or videos inside. So the sketch artists provide alternate images of the main players in the cases for the media. |
How does China benefit from an alliance with North Korea? | The US gives support to North Korea, mostly in food and medicine. It's a tough choice, but morally hard to ignore. Basically if we don't people starve and die horribly. And more starving, dying people isn't likely to mean a popular revolution.\rChina might posture more like an ally and the US might posture like an adve... |
The bodies strewn around Mount Everest | > Whatever financial cost is outweighed by returning the bodies home 1. You're ignoring the potential cost of even *more* people dying on the mountain. 2. Not everyone there would have *wanted* their body to be returned home, and would consider being remembered forever as a marker on the mountain they strove to conquer... |
Why is it so hard to properly replicate the quality of restaurant/takeaway food such as curries/chicken/pizzas at home? | It depends on the food. One big thing a restaurant has going for them is that they make that food a lot. They've got the oven/griddle/whatever at the exact right temperature , and a guy who works 5-6 days a week is making that same dish he's been making all the time for the last year. Another is specialized ingredients... |
Why can't we taste when we are sick? | Your nostrils are most likely blocked with excess amounts of mucus. Smelling is nearly a bigger component to taste than your taste buds themselves. When you can't breathe through your nose, the foods smell can't stimulate your olfactory senses, therefore, diminishing your sense of taste. |
Why its usually much cheaper to manufacture outside of america. | It's a combination of weak labor laws and environmental laws. Cadmium is the perfect example. It's biggest use is nickel-cadmium rechargable batteries. There are no more operating cadmium mines in the united states. The last mine closed down because of china. Cadmium is some nasty stuff and you need to be careful to ke... |
Why did creatures in ancient times (dinosaurs) grow to be so much larger than creatures we have now? | A number of factors such as higher oxygen levels in the atmosphere, warmer avg temperatures, abundance of vegetation, very large migration ranges |
Why is it significantly cheaper to fly throughout Europe than it is to fly within the continental US? | Europe is ~~smaller and~~ denser than the US, which means a flight to a location probably isn't as far to start with. Also because of Europe's density, airline travel has to compete with passenger train service, where the trains in the US are primarily for freight.I would like to throw in that Europe has a robust rail ... |
Why do some cars have one exhaust pipe and others have two of them? | It's an arbitrary decision by the car designer. It is true that the exhaust system creates some back pressure, and that thicker or more pipes would reduce this pressure, but if you look at the pipes under most cars, you'll see one pipe go from the engine through the catalytic converter towards the rear, at which point ... |
If people don't see the same red that I see. How is that color known as red? | Because society in general has deemed it that color. If you were taught from elementary school that the color we know as blue was really called red, then you'd think the sky was red, associating the color blue, with the word red, until a million billion people repeatedly say that it is not red, and then you'll learn it... |
I'm sick. Where does all of this snot come from? I figure blowing my nose would get rid of it all but I seem to have an infinite supply. | It's made from a protein called mucosin. Not that imaginative, eh? Anyway, mucosin expands massively when it comes in contact to water , so 1 gram of mucosin, plus 1 gram of water makes either 60 or 80 ml of goo. But it would weigh 2 grammes, because it's a weird chemical reaction, not an impossible one.I believe there... |
Why haven't wages for the middle class increased whatsoever since the 1970's? | Wages [have increased], but not at the same pace as inflation. So, one major problem is that inflation is growing faster than wages. Another issue is that wages are not the only aspect of an employee's compensation. While wages have remained fairly stagnant, [benefits] have generally been increasing. In 2014, benefits ... |
Why are people allowed to create merchandise for others' works, like Sailor Moon t-shirts or Calvin & Hobbes decals, and sell them for personal profits? | They aren't actually, which is why I've never done it. Most people that do it either don't know or don't care but could face very heavy fines or jail time depending on how much they profited and for how long!", 'Is it only bad for the person creating and selling them or can a person purchasing one get in trouble as wel... |
Why is it important to know so many digits of pi? | It is possible that, through learning the ever-larger values of pi, that we may discover certain symmetries in nature which are presently unknown to us. I mean, what if some gajillionth pi place revealed a whole bunch of prime numbers in a row or some other surprising and unexpected symmetries .? I think that the real ... |
Why do so many people watch other people playing video games? | Why do people watch other people playing sports? its pretty much the same thing People like watching people who are better at them in things they're interested in do that thing. Or, for some streamers, its less about the game and more about the personality of the person playing the game |
Why is the Confederate flag still allowed? | Because iconoclasty, and historical whitewashing for that matter, are far, far worse than your feelings being hurt by a flag's existence. |
What would a kid sound like if their accent was not influenced by anybody? | So who's teaching the child to talk? Whatever voice teaches them is going to have an accent.Some royal back at the end of Dark Ages attempted to find out what the "natural language" of a human is by locking up one of his subjects\' children in a dungeon and forbidding any of his caretakers to speak to or acknowledge hi... |
What is Municipal Broadband? | Infrastructure used depends on what they want. Typically, they want the biggest bang for their buck so currently it's all about fibre. Issues:The incumbent telecoms not wanting municipalities to step in to compete. This has typically resulted in lots of civil cases to block and/or delay municipal broadband.The fact tha... |
Why cant severed body parts grow back? | Because we scar. To a monkey in the woods that is preferable to regrowing limbs. Regenerating limbs takes a lot of time and nutrients and it leaves the site vulnerable to infection. In contrast, rapid scabbing/scarring seals the wound quickly. Without modern medicine, any trauma severe enough to sever a limb will likel... |
What are hydraulic presses actually used for? | They're used for all sorts of things that require a whole lot of pressing force, just as described below. Forming machines are a good example - think of it like a cookie or cake mold, except is smashes down on a slug of metal to form it into a shape. Presses get used for stress-testing in a lot of industries as well. A... |
Every year, more money is "pumped" into the economy, and prices go up, wages go up, expenses go up... Where does all that money come from? | There is no gold in the federal reserve. Hasn't been seen in over 50 years. We literally are just printing money at this point and putting a loaned value on paper. We are living in a crazZzy world. That's all folks. |
How do babies learn to lie? | Toddlers will first start to tell simple self-serving lies at 2-3 years old. They may not know it's wrong, and may be testing out a new ability as they begin realizing they can have thoughts/knowledge/beliefs on their own. Also, kids absorb everything, including the fact that Dad is lying to the neighbors about who ble... |
Why do people who don't regularly smoke, do so, when drinking alcohol? | I used to smoke for 4 years and suddenly just lost the appeal. For some reason alcohol and adderral make me crave cigs. It's really weird because I would neverrrr smoke one sober or high even. It's just like PB & j |
Why are dogs way more happy/excited to someone, and humans aren't? | It isn't socially acceptable for people to greet each other like dogs. So while I may feel the urge to wait by the door and then jump on my husband and kiss his whole face the moment he gets in, I kinda keep that shit to myself until a more appropriate time. |
What is the Loudness War and what side am I on? | Music sounds better at high volumes. Partially because you can hear more intricacies and you're more immersed, and partially just because that's how our brains work. Therefore, over the past few decades, producers have been mastering songs louder and louder, constantly running up against the physical limits of their me... |
what is string theory. Literally eli5. | String theory is a mathematically possible explanation for how all the laws of physics are related. It's not well explored, and there is significant doubt that it could be proved or disproved. If it isn't falsifiable, it isn't a scientific theory. IF it were scientific, AND IF it were true; then it would be a very help... |
How can Marijuana be legal on a state level while it's illegal on a federal level? Does the federal law mean nothing? | Your mom and dad say you can't have candy before dinner because it spoils your appetite. When your are hanging out with your uncle and your parents aren't around he lets you have candy whenever you want. Your mom and dad could still punish you if they found out, but they probably won't . They could also get mad at your... |
Why do so many older people seem to lose empathy for young people even though they went through the same things? | Because young people problems are bullshit. Once you get a little older you'll realize how asinine the problems of teenagers are.Ask yourself how you got through problems you had 5 or 10 years ago. Most people's response would probably be something like, "well, I just did." So I 'd imagine a lot of it boils down to the... |
If dollars are created when the Fed loans to banks where do the extra dollars come from to pay off the loan? | The main way dollars are created is when the Fed buys US treasuries from whoever happens to be selling them for the best price. That means it is the federal government who has to come up with the dollars to pay them off. They can do this primarily through this taxes, or issuing and selling more treasuries. When the Fed... |
Why are there more melanoma cases than ever before, if we have sunscreen and protections? | We weren't able to detect melanomas and diagnose skin cancers until more recently so I'm not sure there are necessarily more instances but rather more instances that we know about. |
Why do you need a Master's Degree to become a librarian, especially when the median salary is barely above $50,000? | Edit: Thank you for the gold and the many kind comments. It's been a wild 16 hours. I'm halfway through my master's right now. Classes center around three topics. The philosophy of librarianship The business side and management aspects of running a library The nitty gritty of turning raw information into a searchable f... |
Why was it actually so hard to find a job during the Great Depression? What happened to all the other jobs? | The Great Depression was a credit implosion. Where did the money go? well apparently it was mostly theoretical. What happened was similar to the 2008 nonsense: Bob lends money to Phil who lends money to Jeff who lends money back to Bob.. only more complicated. So a lot of jobs were being paid for by borrowed money and ... |
Why does the moon appear to "follow you" as you move/drive? | the angle between you and the moon doesn't really change much, so it always appears in the same place relative to you |
Why do we sometimes have a "blink-and-it's-morning" sleep? | ITT people who haven't experienced what OP is talking about but think they have. OP isn't talking about not remembering dreams or falling asleep quickly and waking up the next morning not remembering. He/she is referring to a phenomena that has happened to a lot of kids where you literally look outside a window late at... |
What would happen if every car at a traffic light started moving at the same time, at the same speed? | They would accelerate to the speed limit while remaining extremely close to one another. There wouldn't be any direct accidents from the acceleration, but you'd quickly find yourself going 45mph while only a couple feet from the car in front of you, so the chances of something happening down the road are significantly ... |
Why are the planets in the middle bigger than the planets on the ends? | I'll try - seeing that I have a 4 y.o. of my own. You see, the middle planets are not bigger. They're actually small, but they look fat, like mommy. Why do they look bigger? Because they wear these loose gowns that get filled with air and gases and other things. So when we see them from far away, they look bigger. The ... |
Why does almost the entire Brazil world cup team go by just one name? Seems pretty precocious, like they all attended THE Ohio State University. | I'm no expert but in general it is either because their real names are extremely long and inconvenient for everyone, or they're nicknames. Take Neymar for example, Neymar da Silva Santos Junior is a bit of a strain on the tongue, and fitting it on a jersey would be difficult as well. The history of this practice is als... |
How come the majority of animals have slits for their pupil, but humans have circles? | Some prey animals have horizontal pupils for a wider field of vision and their eyes are often located towards the sides of the skull. Not so great for depth perception, but they can see what's going on around them. Predators usually have forward facing eyes, and the pupils are either round or vertical slits. Vertical s... |
If a 128GB memory card is possible, why can't my phone hold 128GB worth of data? Why is it so expensive for the model with just a little bit more space? | It's the easiest way to make profit off multiple models. Memory itself isn't very expensive, so they make a larger margin off of more memory in it. They know people will pay the extra 50-100 dollars they want for it, while only really cost them marginally more. |
Why during horrific occurrences, do humans put their hand over their mouth? | [This research] seems to indicate that it's not a universal expression of horror. Humans all will [widen their eyes] in response to fear or surprised, but putting your hand over your mouth is probably a culturally learned behavior. |
I am 48. Does it matter if I stop eating processed meat and red meat, or is it too late and my fate is sealed? | The big issue is that everything being reported is a % increase on a base %, it isn't saying you've gone from base 2% to 16%, it is saying your 2% is now increased by 14% - which would be 2.28%. Also - with few exceptions stopping intake of something that is bad for you is better than continuing, and in many cases the ... |
Who is Tom Bombadil and why is he important to LOTR? | Tom Bombadil was a character that was intentionally unexplained. In Tolkien's letters to friends, he had said every epic needs a little bit of mystery. The whole point of Tom is that he remains not entirely explained. |
How come we use an incorrect map? | [Correct maps are also used.] The one you're thinking of was designed for navigators, because it enables certain paths to be plotted with a ruler. But it was never designed to teach people the correct size of things. It's used because it became traditional, and because many people didn't learn about the existence of th... |
How does the smoke detector know the difference betweem smoke and steam? | Smoke detectors work by having a small amount of Americium-241, a radioisotope, and a radiation detector. Smoke contains particulate matter which absorbs some of the radiation, the detector picks up on this and triggers the alarm. Steam doesn't absorb radiation as well so it doesn't trigger the alarm. |
Why does it "hurt" when you swing at a baseball but miss? | Swinging a baseball bat generates a good bit of force, and a baseball moving towards you at 90 MPH has a good bit of force behind it. When they connect two things happen: the baseball transfers its momentum into the bat and the bat transfers its momentum into the ball. The bat is heavier than the ball and is anchored t... |
Why did Mark Zuckerberg have to pay the Winklevosses a settlement? | Because it's not always about who's right or wrong when settling a legal case. You also have to take into consideration how much it costs the FaceBook legal team to continually fight this battle in court and it's effect on consumer, and more importantly, investor confidence. The pay out issued was seen as a bargain by ... |
What is community access (or public access) television/cable and how does it differ from public television, i.e. PBS? | Community Access just lets anyone who wants to air stuff. Public television is run by professionals but is a grant/donation-funded non-profit. PBS shows Sesame Street. The guys from Wayne's World were broadcasting on Public Access. |

When you drink, the alcohol goes to your liver where it is broken down so that you can pee it out. When it gets broken down by the liver , something called acetaldehyde is formed. Now, after only a few drinks, the liver has plenty of tools to bre... |
All the different types of music file such as mp3,mp4, alac, flac. Etc.... | Different ways of coding and compressing audio. FLAC is lossless audio. WAV is pretty typical and mostly lossless. Mp3 AAC are heavily compressed. mp4 is used mostly for coding video with audio. MP3 is compressed in a pretty simple way, for instance instead of writing out a code like 123456666666666 you would write out... |
Why can a watch be made to remain accurate for years, but the second hand never be made to consistently lines up with the tick marks? | /u/malnurtured999 gave a good answer but it could also just be your unit has a slight manufacturing defect. I own several mechanical watches and one of the less expensive ones has a defect where the diving bezel doesn't exactly line up with the ticks. |
What is 'I Think, Therefore I Am'? | It's the fundamental truth which all of us know. If we have thoughts then we must exist, because how else could we be thinking without existing. Descartes in his work the *Meditations* uses this principle to try to build up a whole framework of knowledge of which YMMV about how successful he is. This first principle of... |
Why is it that bugs can survive falls that would be (proportionally), deadly to larger animals? | 1 one inch cube has a volume of 1 cubic inch but it has a cross section of 1 square inch. The strength of of an object is related to is cross section. A 4x4 piece of wood is stronger than a 2x4. If you increase that cube to 2 inches, it's volume becomes 8 cubic inches, but the cross section is only 4 square inches, so ... |
Why is rotisserie chicken cheaper than most uncooked full chicken | The uncooked ones are generally larger in size than the precooked rotisserie chickens they offer. So yeah. That's why. Ignore the rest of this comment. Just making it long enough for the bots to not notice. |
How can my heart rate be low but blood pressure high? | Big number is the systolic pressure, its the pressure in your arteries when your heart is actually contracting to force blood out of the ventricle into the aorta and out into the body. A value of 140 is considered high, 172 quite high. The other number is the diastolic blood pressure, its the pressure in your arteries ... |
Why does a slow hard drive affect everything else on my computer? | Because everything on your computer you're describing is a function of your operating system. Which is software written to your hard drive. Without your hard drive your computer would be a box that shows a brand logo and then does nothing else. No FarmVille, no cat Gifs. |
Why the USA don't have national identity card? | Because it is the State's job to maintain identification, not the Feds. Each state has individual sovereignty over it's citizens. |
Why are things like peanuts and shellfish common allergies? And why are there different typical severities for the common allergies? | yeah, sub-question: how is it that basically no one in my generation has a peanut allergy, but in the generation after , they are much more common, and also MUCH more severe? i've heard a theory that right around that time was when many hospitals switched to soy-based formula for newborns, as well as many mothers eatin... |
How come rapists get longer sentences than murderers in the US? | I would be shocked to find out that first degree murderer's get shorter sentences than rapists.
