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. Depending on how you define a sense, we actually have between 5 and 33 of them.

Beyond the classics, we have a sense of balance and the ability to sense heat and time. That's along with 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 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.

    We lose most of our heat because of skin surface area.

    Most people might think you would lose most of your body heat from your head because your head is the most heated part of your body.

    I thought that was cool because I didn't know about any of that and I really thought we had 5 seconds

    I am so surprised that humans have between 5-33 senses. I was always taught that we had five.

    I think people thought that because your brain is where a lot of blood is being pumped through because if you did not have a lot of blood pumping through your brain, your brain would not function right.

    I thought this was very interesting and I learned things about our bodies that are false when I thought they were true.

    I think this article is very interesting. I really thought we only had a few senses. I also thought kids were wild sometimes because of too much consumed sugar.

    I found this article very interesting. I am very confused how we only use 10% of our brain. There should actually be a higher percentage. The other fact is that not only do we have 5 senses. We have 5-33 senses in our system. This was a fascinating and interesting article and conclude all these facts are right.
