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 might people have thought that we lose most of our heat through our heads?

    I think its crazy how many people think all these myths are true. I didn't know that the myths weren't true and it changed my prospective on everything.

    I never knew that these facts were true because I heard all the myths from all the other people. I think it's very cool that we have 33 senses and that some of the senses are like the spidey senses from Spider man. I think that it is very surprising that people think that it takes 7 years to digest gum which is insane.
