Five false facts about the human body They myth that it takes seven years to digest gum? It's just a myth. (Thinkstock)
Five false facts about the human body
Lexile

You asked us to debunk some "facts" about the human body.  Let's science this!
 
So here are five popular myths that just are not true.
 
First, we have five senses. Right? Wrong. It depends on how you define a sense. We actually have between 5 and 33 of them.

Beyond the classics, we have a sense of balance. We also have the ability to sense heat and time. Along with those, we also have all kinds of other cool spidey senses.
 
Second, what about the idea that giving kids sugar makes them bounce-off-the-walls hyperactive?

Nope. The evidence for that cause-and-effect link is surprisingly slim. It's apparently more of a self-fulfilling prophecy than fact.
 
Myth number three. We only use 10% of our brains. This one drives me insane. It's totally bogus. We use virtually every part of our brain. And most of it is active almost all of the time.
 
Myth number four. Despite all the heavy lifting going on up there, it's totally false that we lose most of our body heat through our heads.

The amount of heat we lose depends on how much skin surface area is exposed to the cold. So, yes, you'll lose more heat through a bald head than a gloved hand. But the opposite is just as true. 
 
And finally, I know what your mom said. But  you can trust me. I'm a scientist. It doesn't take seven years to digest swallowed gum.

The base element of gum is pretty much indigestible. But it'll still pass through our system within a week if not faster.

    Why because the amount of heat we lose depends on how much skin surface area is exposed to the cold.

    People might have thought that we loosed heat through our heads because heat rises so why would it come out of our foot or anything else.

    People think that we lose most of our heat through our heads because we do not always wear hats over the winter.

    I think people think we loose most of our heat through our heads is because how much skin surface is exposed to the cold but yes a gloved hand would be warmer.

    They think that because you might always be warming hats or ear muffs.

    They might think that because heat rises up and your head is on the top of your body.
