#1
Every child's jaw is packed with teeth which sounds normal until you realise this is what it looks like.
JoJo Anisko 1 year ago
This should make you even more aware of how remarkable the human body is, that each of those teeth has a particular place to be, and they mostly end up in the proper place. (Yes, all living things are remarkable.)

That weird feeling you get on a roller coaster is actually your internal organs slightly shifting around inside you, especially the ones not secured by ligaments like the intestines.
#3
If you rub the soles of your feet with garlic, you'll begin to taste it 30 minutes later, there's a compound in garlic that penetrates cell membranes, travels up the bloodstream, and reaches your taste buds. Meaning you can taste garlic with your feet.
#4
The acid in your stomach is strong enough to dissolve razor blades which is why your stomach is in a constant battle to not digest itself. Only being kept in check by mucus.

Props to the guy who swallowed the razor blade so we could know this
#5
When you really think about it we're all just three-pound brains piloting meat bicycles we call bodies
#6
If you force someone to stay awake without giving them any food, they'll die of lack of sleep before they die of starvation.
#7
There's a kind of tumor that can cause teeth to grow in a woman's ovaries and a male's testicles.
#8
Men can actually produce milk, it's more common than you think most men are just too ashamed to admit it. And it can be triggered by starvation. Concentration camp survivors were given food after being starved for weeks and for some reason, they started lactating.
#9
Since you shed about 40,000 skin cells a day, the dust you see in your house actually used to be part of you. Which means every time you breathe in someone else's house, you could be inhaling 1000s of somebody else's skin flakes.
#10
If you decapitated someone, the disembodied head will be conscious for 15 to 20 seconds, long enough for them to realize what you did to them
#11
The brain has no pain receptors, meaning it's possible for people to stay awake and talk to doctors while they're performing brain surgery on them
#12
Because we evolved to walk on two feet, the pelvis and birth canal of women got narrower meaning they have to suffer one of the most painful births on the planet, which is why in 1780 chainsaws were used to saw off a part of the pelvic bone to make childbirth easier.

I have no doubt whatsoever that it was neither proposed nor invented by a woman.
#13
Sometimes when you have a runny nose, it isn't snot. It's cerebral fluid that the brain leaks to reduce pressure.
Purple Rainn 1 year ago
This isn't quite accurate. Yes, it can happen, but it's pretty rare, it happens when there's a hole in the membranes around your brain or spinal cord, not just to reduce brain pressure, there's usually other symptoms associated with it, and if it does happen, you should see a doctor. It can heal on its own, but it also puts you at a risk for meningitis.
#14
Sometimes during brain surgery, they'll peel your face forward like a goddamn banana.
Robert Trebor 1 year ago
If it'll peel, it'll heal. Rather have my face temporarily stowed near my nose than have major scars that would scare children and small animals.
#15
One of the first things a surgeon does before the surgery is clean out the belly button because there can be 67 types of bacteria in there.
#16
If a woman's ligaments stretch and her muscles aren't strong enough her uterus can straight up fall out of her. Kegels are your friend.
#17
When you breathe, most of the air goes in one nostril and comes out the other and they switch roles every couple of hours. And you're checking right now, right?
HelluvaHedgehogAlien 1 year ago
Also, when you realize you are breathing, it switches from automatic mode back to ‘oh, so you’re back again! Here, focus on breathing so you don’t die!’ mode
#18
You produce more earwax when you're stressed and stressed earwax smells way worse than the regular stuff
#19
Your immune system doesn't always recognize the eye as part of the body which is why there are many diseases where the immune system attacks and tries to destroy the eye which could blind you in the process.
#20
There could be mites having sex on your eyelashes right now you would have no way of knowing
#21
Your brain lies to you all the time. if you turn your head too quickly, your brain can't possibly process everything. So it'll take what little information it was able to grab and fill in the missing blanks. There's another way your brain kind of lies to you. If you cover one, the reason you don't see a big black void in your vision is because the brain basically makes up and fills in the missing parts based on the surroundings.
Superninjatiger 1 year ago
I have vision loss in some parts of my eyes (I'm going to a eye specialist on tuesday and I'm scared of what might be wrong) so my brain does this all the time, it's really weird because sometimes I don't see things because they're at the "wrong" place for my eyes and they just fill out the gap with whatever is beside. So like on a paper some of the things that's written/printed on it is gone and the space is just white.
#22
The water you drink has probably been inside someone or something else.
#23
When you die, your body will begin digesting itself as enzymes eat through cell membranes and leak out.
#24
You can exchange as many as 80 million bacteria in one 10 second kiss, and if you kiss your partner multiple times a day you'll develop similar colonies of oral bacteria.
#25
If someone sneezes in your face, they're launching germs at you at 100 miles per hour. Coughs aren't that bad because they're only about 60 miles per hour.

My youngest child running at me yesterday sneezing in my eyes! Lol oh my downvoter is back. Following me about like a scary stalker
#26
You aren't actually you, you're just a brain controlling the body. The things that make you you is decided by a three-pound wrinkly mess of tissue.
#27
Placentophagy is the practice of a woman eating the placenta that comes out after she gives birth. And apparently, she has two options. She could cook it or eat it fresh out. A Canadian study claimed that 24% of women polled ate the placenta.
Dontyouwishyouknew 1 year ago (edited)
Eat it fresh out?! That's a bit much. I mean other mammals do it but I can't wrap my brain around a human doing that. Haven't looked this up recently, but I've heard of drying it out and putting into a pill form and just taking it like a daily vitamin. Edit: if you've eaten a fresh placenta, no shade to you. You do you. Not trying to offend anyone.
What do you think ?

Here's a fun fact. When a man and a woman have a baby, if the woman then needs a kidney, the man *cannot* be considered a donor. It has something to do with the fact that his genes have been inside her making the baby, her body's immune system had to do weird and wonderful things to avoid rejecting the baby, but it means that any donor kidney *would* be rejected immediately. It's more complicated than that, but there's a character limit and I'm not a genetic biologist to be able to explain it any better.

I don't think this is entirely true. I could only find limited info on this issue and from the abstract of this research article it appears that mutual children is not necessarily predictive of rejection: https://www.frontiersin.org/articles/10.3389/fmed.2021.724851/full ... from the article "husband specific sensitization is around 20-50%"

Here's another fun fact. The team of research scientists who flew to Antarctica looking to find the cause for the hole in the ozone layer were woefully unprepared for the conditions. They forgot to pack a targeting system for one of their radio dishes, so somebody had to sit on the roof and target one of the dishes at the moon. At one point the scientist noticed she couldn't open one of her eyes. It had completely frozen. Luckily it thawed without complications, but that must have been quite disturbing to realize your eyeball is completely frozen.

Your body is a big jiggly mess of all different kinds of cells, enzymes, chemicals, bacteria, and fungi working in a bizarre balance dictated by billions of years of evolution and/or a glorious creator. It's a freaking amazing piece of hardware.

I saw that brain surgery face skin thing, and thought “this seems like a fun thing to find a video of” I found one, and I almost passed out. My vision got blurry, and I started feeling really dizzy. This is a rather common occurrence with me. This has happened from heat exhaustion, and from getting shots. I really hate needles so it usually happens then. I seriously regret finding that video, and I highly suggest NOT TO MAKE MY MISTAKE.
