29 Myths Even Your Parents Thought Were True

[Music] hi do chameleons only change color for camouflage no they can actually change colors to reflect their mood so males turn a bright color to show their dominance and they become darker when they get aggressive chameleons also change color to adapt to different temperatures a cold chameleon will turn dark to absorb more heat while a smoking hot chameleon will turn itself pale to reflect the sun's rays by the way do comedians change color for camouflage only if their jokes aren't getting any laughs okay i made that up now there's a myth that if you drop a penny from a skyscraper it'll pretty much destroy whatever's underneath but when put to the test researchers found that it just isn't true on its way down a coin can't gather enough velocity to cause permanent damage to anything mostly because of wind resistance and the penny spinning around and stuff anyway just hang on to your change now some people believe that toilet flushes spin in the opposite direction in the southern hemisphere some things are affected by the earth's rotation like the gulf stream or hurricanes but toilet flushes are way too small flushes can spin in either direction whether they're in the northern or southern hemispheres trust me i know the biggest determinant of flush direction is the design of the toilet bowl and the water pressure there's a popular saying that lightning never strikes in the same place twice lightning often strikes near the same place a lot more than that lightning generally chooses the tallest pointiest spot as its target researchers have found that the empire state building gets struck by lightning almost 100 times a year and quite a few people have been zapped more than once like a lot more so if you're tall and pointy be careful out there so there's a common belief that bats are blind but bats have better vision than humans at night although humans can see more clearly during the day maybe this myth came about because bats rely a lot on their hearing to get about or maybe it's because bats see the world in black and white now the goldfish really have short memories well most people put it at seven seconds in reality goldfish can remember things for as long as seven months without a good memory goldfish who live in nature would never find food did anyone ever tell you that a mother bird will reject its offspring if they've been touched by a human that would be nuts because most birds don't have a developed sense of smell they'd never be able to identify the scent of a person the vulture is an exception to this rule it has an amazing nose but then who'd want to touch a vulture anyway ostriches bury their heads in the sand when they're scared except they don't this myth probably came into being because an ostrich's head is disproportionately small in comparison to its body so from a distance it looks as if the ostrich has its head stuffed in the sand but if it really did that it would pass out from not being able to breathe another myth is that opossums hang on branches with their tail the opossum does use its tail to help it climb trees but its tail can't support its weight even a hulked out calisthenics master opossum could only hang there for a few seconds max legend has it that a penguin will fall backward when looking up at an aircraft cutest myth ever penguins can maintain their balance no matter what even while looking up at the sky but low-flying airplanes may cause penguins to flee their nests in panic do dogs really sweat by salivating no they sweat through their foot pads but salivating and panting does help them regulate their body temperature cat owners may think that a cat only purrs when it's happy but cats also purr when they're hungry distressed or recovering from an injury researchers think that purring may be a self-healing trick somehow it keeps their bones and muscles working better legend has it that if you run into a skunk there's only one possible outcome you're gonna stink for a while but skunks prefer to flee from danger rather than spraying their magic juice around that smelly sprays their last line of defense before that they usually stomp their feet and slap their tails to ward off any danger did you know there's an alpha wolf in every pack except again there isn't unlike captive wolves wild wolves don't share this kind of social order they live in family groups like humans where the parents are the leaders and the little ones gotta do as they're told there's a myth that owls can turn their heads full circle but that would cause them significant damage but still they can turn their heads comfortably more than halfway around because of their unique neck bone structure if you've ever poked a turtle shell thinking it won't hurt the guy inside you'd be wrong a turtle shell is a living and feeling part of its body with a complete nerve ending supply if the shell gets damaged it can even endanger the turtle's life there was a time when people thought that unwashed hair was the ideal habitat for headlights but head lice don't discriminate no they can make themselves a home in all hair types all they really want is a warm scalp most people are familiar with the phrase an apple a day keeps the doctor away apples are good for you sure they're packed with nutrients like fiber and vitamin c but does anyone really think that's enough when it comes to food hygiene the five second rule just doesn't make sense there should be a where you drop it rule to replace the five second one generally if you drop food on your kitchen floor it's gonna pick up fewer bacteria than if you drop it at the checkout counter of a busy supermarket of course that's assuming your kitchen's clean uh-oh ever wondered whether the story about chewing gum taking seven years to digest is true nah it isn't chewing gum isn't too different from any other food it takes around the same time to digest but it's not exactly nutrient heavy legend has it that catching a cold is likelier to happen in cold weather but studies have shown that weather doesn't really play a part in getting a cold a virus does people may experience more cold like symptoms when the weather is icy cold but temperature has nothing to do with recovery time or anything like that do people only use 10 percent of their brains well i have some friends who seem to never mind no the answer is no scientists who've studied brain scans say they don't show any large dormant areas of the brain but if the myth is just about humans having a long way to go to reach their full potential yeah that sounds about right one of life's no-nos is to jump into the pool right after eating but hitting the gym after a big meal can leave you feeling just as uncomfortable as doing a few laps also if you're worried about getting a cramp in the pool those can happen anytime not just after a meal does shaved hair grow back darker and thicker researchers say it doesn't but shaving does give your hair a blunt tip which can make it feel thicker when it comes to color that new darker stubble is just an illusion some people are convinced that eating turkey leaves them feeling drowsy it's true that turkey has a chemical that can cause drowsiness but so does chicken or beef turkey is a favorite for those massive family celebrations so that drowsiness it's probably due to the huge amount you ate the myth that people lose most of their body heat through their heads was probably first invented by a hat salesman not surprising scientists say that people lose only about 10 percent of their body heat through their heads you lose heat through your skin no matter where that skin is have you heard the saying that a full moon can affect your mind somehow and no but researchers believe that light from a full moon can affect your sleep which can affect your mood did ancient vikings really wear those awesome horned helmets there's no real evidence to back up this claim this myth probably came from books and music looking to spice up their heroes a bit if you want to see a viking with a helmet go to a minnesota vikings game that's about as close as you're gonna get some people believe einstein flunked math in school einstein himself debunked this theory by saying he mastered calculus at age 15 but einstein did fail to enter the school of his choice because he flunked languages on his first try but math he passed with flying colors
