Doctors Reveal Creepy Little Things You Don't Know About Your Own Body

List Rules
Vote up the strangest facts about the human body.

The human body is a revolting, ever-flatulent mechanism that just doesn't know when to quit. Most people romanticize the human form, lauding its ability to withstand great forces and its inclination to imbue the world with additional bodies. Those attributes are rather outstanding but the body does so many gross little things that any good deeds are overshadowed by the yucky ones. 

Doctors, strange beasts that they are, have taken it upon themselves to study the corporal form. They see all manner of weird bodily functions and they've been known to commit some egregious medical practitioner blunders of their own. Who can blame them, though? Working on a body is tricky.

A few brave doctors aligned on Reddit, sharing stories about the gross things that supposedly awesome bodies do all the time. Perhaps you'll reevaluate your stance on body positivity after you read the following gripes.

    The Heart Can Recognize People From Far Away

    From Redditor /u/AverageCommentary:

    Our hearts generate an electric field a few times stronger than that of other organs and a magnetic field thousands of times stronger than that of other organs.

    I'm sure a lot of you have had a situation where you're walking down the street and out of nowhere you're suddenly thinking about a specific person only to bump into said person a few seconds afterwards. The heart basically detects the magnetic field of other hearts and recognizes it without you even realizing it. Thus, it recognized your friend's magnetic field and sent signals to the brain and because of that, you started thinking of your friend.

    Lots of people don't know they have things called "[sesamoid]" bones... they are bones that just kind of free float around...

    Lots of people have them in the joints by their thumbs, the back of their knees, and even in the bottom of your toes.

    Tumors Can Dictate The Growth Of Additional Arteries And Veins

    From Redditor /u/docfelt:

    While there are countless fascinating things about the human body, one of the coolest things I've learned so far is angiogenesis of human cancer tissue. The tumor will sense it needs more oxygen and nutrients and turn on the angiogenic switch which expresses proteins that will freaking make arteries and veins that attach to the tumor. It's insane.
