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, 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 - 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. 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 7 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.

    People have might of thought we lost out body heat through our head because we use our brains all the time no matter if we are sleeping or if we are awake. But scientists say that the way we lose most body heat is through our skin if a cold surface is against it. I think that is really cool.

    People might have thought that we lose most of our through our heads because you head is hot after you work out.

    People may have thought that we lose most of our heat through or head because they might have thought the hair makes it hot and sweat more.

    i'm not sure why people would think we lose most of our heat through our heads. Maybe it's because they believe our skin is too thick or something- not sure.

    They might have thought since the head is what does all the thinking and they might think we lose heat that way.I never knew we had 5-33 senses.I also thought gum took 3 years ,buy it turns out only a week.

    People might think that we lose most of our weight from our heads because we don't have that much skin their but it depends how much skin surface area is exposed to the cold.

    It is cool how we have between 5 to 33 senses. Some other senses that we have are that we can sense heat and time.

    It surprised me of how many of these "facts" that I learned were myths. I really though that gum would take a long time to digest, not less than a week. I hope these myths do die out soon.

    I did not know that it only took a week or so for gum to pass through your body. I thought it took more time for gum to go through your body. And I thought gum was digestible after a long time.
