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

You asked us to debunk some "facts" about the human body, so let's science this!
 
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, 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 and it's apparently more of a self-fulfilling prophecy than fact.
 
Myth number three is that we only use 10% of our brains. This one drives me insane because 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 is that 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.

    These were intriguing myths especially the one where people think we lose most of our heat through our heads. I have just come across that one. Nonetheless, the article was quick to read and interesting all the same. I like it.

    People might have thought that because people sometimes sweat a lot through their face or on their scalp due to sports or just because it may be hot outside.

    This was a very interesting text. Many of us have previously believed in these myths and lived by them. We stopped ourselves from swallowing gum, thinking we use 10% of our brain and more. Now I am knowledgeable enough to inform others of the truth, restricting them from believing what others opinions are.

    People might have thought that we lose most of our heat through our heads because when it's cold, our head is normally the only thing not covered.

    People might think this because it's what they have been told all their lives and because it makes sense since heat rises.

    I already knew a few of these facts were false, but I always believed that we lose most of our heat through our heads. Not because I experienced it, it was just something my mom always told me, so I took it for granted, and I think it might be a similar story for others.

    I always thought of these 5 facts to be true. I think it's crazy that we may have 33 senses and I would like to look into what those might be other than the normal 5.

    People might have thought we loose most of our heat through our heads because it is he most sensitive part of our body.

    Although I never believed the myth that we lose most of our heat through our heads, I have known people who do. I think they thought this because, since our heads are almost always exposed, they might feel they are losing body heat through their head. This of course is true, but only for that scenario. Maybe, since they felt body heat leaving through their head with clothes on, they thought that was just the way their body regulated heat.
