Humans only use 10% of their brains

 This is a misconception that EVERYONE has heard of. Is it true? Nope. Not at all. In fact, some neurologists laugh even at just the thought of it.

So what is the truth? 20%? 50%? 75%?
Well, according to neurologist Barry Gordon from Johns Hopkins School of Medicine in Baltimore, "It turns out though, that we use virtually every part of the brain, and that [most of] the brain is active almost all the time". So really, throughout the day, humans use most of our brains most of the time. An exact percentage varies a bit

Tongue Taste Twist

Here's one you've probably heard before. People around the world believe that the tongue has certain areas that are used to identify different tastes. But, they are wrong. The TRUTH is that all areas of the tongue can more or less sense the different tastes equally. In fact, other areas of the mouth can too, like the back of the roof of your mouth. Why? Because these areas have taste receptors. But why did people ever think this was true? It all started with a scientist from Germany, D.P. Hanig. Hanig used a large group of people to see what areas of the tongue are more sensitive to what tastes. then, another scientist named Virginia Collings took Hanig's findings and converted the sensitivity ratings into numerical

Food isn't dirty if it has been on the floor for 5 seconds or less.

 

Otherwise known as the "Five Second Rule", this myth has been circling English speaking countries for decades. 

But is it true? 

Does it even make sense? 

Actually, how do I put this, 

 Logically, this idea is absolutely false, a lie, NOT TRUE whatsoever. The moment food hits the ground, bacteria or "germs" as shown in the first image don't wait for 5 seconds. Why would they? Of course, there are variables. For example, food falling on the floor of a public restroom will likely pick up more than maybe if it fell on the floor of your bedroom or a hospital. Then there's also the food itself. If it is wet, it will pick up more bacteria than something dry like a cracker. Plus, not all bacteria is "bad". In fact, some bacteria exist inside you to help with digestion and to fight the "bad" bacteria. Even so, you have no way of knowing whether the bacteria the food comes into contact with is "good" or "bad" unless you are a Mythbuster (or scientist) and have access to equipment to check. So why risk it? It isn't worth getting sick for, just find a replacement for that slice of pizza (or whatever fell) and eat "bad" germ free.

By the way, the Mythbusters actually busted this myth themselves as a mini-myth. Wanna see their results?

Verdict: FALSE

Why do Chameleons change color?

Lots of people think that the reason a chameleon changes color is so it can blend in with it's surroundings. Actually, this was something that people assumed after seeing them change into colors similar to what's around them. In fact, how they change color wasn't even known until recently, so, I suppose that this guess about why isn't too far-fetched, or unreasonable. Or completely wrong. Camouflage has its part in why chameleons change colors, though small. Actually, it seems that the main reasons for changing colors have to do with a chameleon's mood, and needs. For example, if a chameleon is a darker shade of a color, it tends to mean it is angry. Lighter shades tend to be used to attract mates. In other cases, color change can be used to control the level of heat a chameleon  absorbs. Darker colors absorb heat, so if a chameleon is cold, it might change into a darker color. Or on the other extreme, they might change into a lighter color if they are too hot.

Verdict: Whatever the reason, I think we can all agree that chameleons are awesome!
