#1

Your intestines “know” what shape they’re supposed to be in, and can move themselves, which means gut surgeons can just stuff them back into you when they’re done and they’ll sort themselves out.

#2

When you get laser tattoo removal the ink doesn’t disappear, you pee it out.

Your body’s immune system breaks down the pigments of ink and it flows in your blood stream, gets processed through your kidneys, then you pee out the ink.

#3

Your tongue has **incredible** tactile capabilities. So much so, that if you look at any object, you can vividly imagine what it would feel like to lick it. Go ahead, look at the wall, your shirt, your shoe—the tongue knows.

#4

The liver can grow parts of itself back.

If you get a splinter or foreign object stuck in your skin you can hold a flashlight against your skin and shine the light through your flesh, and the foreign object will be a dark spot. Light actually passes through our flesh quite well. Also, if you shine a bright enough light into your mouth you can see the light in your own eyes.

Edit: I’m really glad that so many people have gotten out their flashlights and had some fun with them! Never stop exploring and being curious and trying to discover new things! The world is amazing and has so much crazy stuff to uncover! Y’all keep having fun now, and thank you everyone for all the wonderful replies and absolutely making my day!

People keep saying “your brain” in these comments. I think one of the creepiest things is that you are the brain and the brain is you, but for some reason we brains really don’t like to acknowledge this.

Incident number 1: I had a bad enough broken bone when I was 9 that it almost killed me. Apparently the marrow that makes blood can’t exist in your bloodstream, fun fact lol.

Incident number 2: My orthopedic surgeon and my neurologist still don’t have a good explanation as to how I have full range of motion in my legs (ie: the ability to walk/run even) I’ve never seen a super smart guy like my neurologist just go “I don’t really know?” after I had broken my back and had nerve damage and partial paralysis in both legs. My neurologist says that sometimes cerebrospinal fluid can act as a bridge for major nerve damage so MAYBE that. Otherwise? He wrote some published stuff about it that was more question than answer haha.

All I know is that when I get x-rays done or switch doctors, the response is “how did you walk in here??” it visibly unsettles them. Like I’m playing a prank and my wheel chair is hidden somewhere lol. I don’t really care, if I’m being honest. It hurts a lot sometimes, and people get really weird sometimes when I remind them that I can’t do some things but, *shrugs* I can walk so it doesn’t matter much to me.

Long story short, sometimes your body can do some weird and creepy s**t that even the professionals go…..”ehhhh?” about lol.

Food that was consumed can sometimes take up to 5 days to fully pass through your intestines into your colon. So when people say that you are full of s**t, they ain’t lying.

#7

Bodies will move as they’re coming out of rigor. I’ve been bumped by a few (I’m a coroner). Bodies can also make sounds as the remaining air/ gas leaves… 2am in the morgue and I thought I was in COD zombies.

#8

The pain you feel from a sunburn is your skin cells effectively killing themselves before they mutate into cancer.

#9

A dead body will often move as its being cremated. Muscles contract as they cook, after all. Sometimes this means a body will sit up in the crematory machine.

#10

The front of your tongue is curious, constantly patrolling, and autonomous. It chases the dentist around your mouth and you aren’t even aware of it. So embarrassing and weird/creepy.

#11

Human skin is overlaid with a pattern called Blaschko’s Lines, stripes covering the body from head to toe. The stripes run up and down your arms and legs and hug your torso. They wrap around the back of your head like a hood and across your face. You just can’t see them.

#12

Human beings are a cesspool of bacteria and when you die your body eats itself from the inside out.
