Every child's jaw is packed with teeth which sounds normal until you realise this is what it looks like.
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.)
I had 7 extra wisdom teeth. XD those teeth did NOT have any particular place to be. The dental surgeon said if I’d been born in a time before modern dentistry, the wisdom teeth would have become impacted and probably have killed me before I was 25 XD
Load More Replies...I still have one of my baby teeth. The adult tooth never pushed out - still in there above the kid. Sometimes I want to be like that hiding tooth.
I had a baby tooth too, because the adult tooth was growing completely sideways into all the roots of the others like "I'm on an adventure!". Had to have surgery to remove some of bone from my jaw to get it out and put an end to its shenanigans.

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.
Let's put it like this: if your organs were fastened more securely in place they could tear loose from.their moorings, causing a lot of trauma at even less stress than you get on a rollercoaster. So it's kind of a feature they can wander a bit when enough force is applied. They tend to settle back in their rightfully places quite fast I believe.
Load More Replies...Ain't nature wonderful...ly terrifying sometimes.
Load More Replies...Fun fact- if you have a cesarean you get this feeling randomly as your organs shift back into place.
Didn't happen to me, I had very fast uterine involution and it felt like painful contractions.
Load More Replies...Roller coasters cause cataplexy in me, and it is terrifying! It causes my arms and hands to become too weak to hold on. So, as fun as they are for many people, for me they are now on the no-can-do list.
It's okay unless you are a horse. Humans' interiors are well secured (tied down). But horses' intestines are sort of just in there, and can be taken completely out through an incision in the belly.
Well, maybe better but still quite flexible and springy. The looseness helps the force of f.i. big falls dissipate more safely via the organs sliding around a bit to lose energy and later settling back.
Load More Replies...My husband spent a good deal of his life with his organs pushed together by cysts once they were removed he felt his organs shift for the first time. He was not a fan.
I've seen stories where people have passed kidney stones after a roller coaster. Could be coinkydink, of course.
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.
Ok I really want to try this now but I don't have any garlic. Any pandas out there willing to make the sacrifice in the name of science?
Didn’t work. My feet smell like garlic and my neighbors are looking at me like I’m insane from what just happened in my garden. LOL.
Load More Replies...I had a coworker who felt the need to share with me that she put garlic up inside her because she had a yeast infection and heard it could cure it. She said she could taste it in her mouth after a while.
They don;'t normally do. The garlic thing works because it contains essential oils, which have a very strong smell. This is why a person can exude the smell of garlic even hours after eating it...
Load More Replies...Anybody else tastes the bitterness of eye drops after putting them into your eyes?
That has nothing to do with the compounds in the eye drops. There's a direct connection from your tear ducts to the back of your throat through your nasal cavity. You know how your nose starts running when you cry and when your nose is running, you can suck the snot into your throat? It's the same system.
Load More Replies...If you are congested, rub Vicks on your feet ... Your nose will clear up in no time!! Awesome remedy for a baby with a cold 👌
Why doesn't this work with hands then? I handle raw garlic a lot, and never experienced this.
If you chop it in your food, you'll probably taste it off your plate first. (also, most people wash their hands pretty often while cooking)
Load More Replies...Yeah and if you eat too much pickled garlic, you'll reek of it for days...... found out the hard way... alas, I no longer eat jars of the stuff.
Same thing happened to me.. I eat less garlic now
Load More Replies...If someone rubbed my feet with garlic, I would be terrified that they were about to pop me into a hot oven.
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
Someone... might actually have done this. Semi-consensually. There was a guy who, through an accident that I won't go into, ended up with a stomach fistula, and a scientist was fascinated by it and basically made him a guinea pig for seeing how long it took various things to dissolve in stomach acid... it's complicated and fascinating and fairly disturbing. You can look up Alexis St. Martin for the whole bizarre story.
Load More Replies...I can imagine that the corn doesn't stay long enough in the stomach for it to dissolve, but if you put something for a longer time it will.

If you force someone to stay awake without giving them any food, they'll die of lack of sleep before they die of starvation.

Depends on how skinny they are and how much water you allow them to drink.
There's a kind of tumor that can cause teeth to grow in a woman's ovaries and a male's testicles.
Dermoid cysts or teratoma. I had mine taken out with one of my ovaries. I wanted to see it after the survey but I wasn't allowed.
I had two, but my ovaries luckily stayed. I didn't want to see it but they showed me pictures of my ovaries and uterus and explained what they did. Even told me what was inside the dermoids... the doctor was maybe a bit too enthusiastic 😂
Load More Replies...It’s called a teratoma and they can also grow hair, nails, and I think some organs?
If that's true, that is absolutely terrifying. Like tumors are evolving to be a whole other being? Yikes!!
Load More Replies...Oh, I've seen one in the lab I was working during summer when I was at university. They always check for tumor when extracting cyst. It's honnestly pretty weird to find hair and teeth in an ovarien cyst but this type of cyst apparently never turn into cancer.
Unfortunately, that isn't true. Teratomas can be mature or immature. In a mature lesion, the different types of tissue present (like intestinal mucosa, glands, muscle, cartilage etc) are fully mature and look identical to the appearance of the cells in the tissue in its proper location, so gut lining in a mature teratoma looks like gut lining in the normal gut. In an immature teratoma, the cells in the tumour are still recognisable as different tissues, but they recapitulate the appearance of cells at an earlier stage of development, so liver in an immature teratoma looks like liver found in an early fetus, not an adult. Mature teratomas are more common, and they've a 2% risk of malignant transformation, but the risk for immature teratomas is much higher.
Load More Replies...Oh so the movie Teeth can actually BE based on a true story?
Yes teratoma. My granddaughter at 14 had a 2.2 pound teratoma removed from her chest. Unfortunately they had to crack her chest open but it was not cancerous so that was good news. Usually in the chest they are not. Her tumor didn't have teeth or hair but it did have skin cells in it. Hers was very dangerous, it was resting on her heart and up against her esophagus. She always had a cough and became hard for her to breathe. She had to go to a special children's hospital out of the area. She is fine now
That was difficult to read, and must have been terrifying for you to live through... hope you and your family are thriving.

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.
Double checked this, because of course there's no source. It's true. https://www.scientificamerican.com/article/strange-but-true-males-can-lactate/
My husband can squeeze out this kinda milky liquid out of his nipples. It’s a apparently a party trick for him.
I'd get him checked out though. Non after birth lactation is a sign of possible breast cancer in women and men.
Load More Replies...Yes, men have all the same structures in their breasts as women. Men can also get breast cancer. Any man who has a discharge from a nipple should run, not walk, to his physician to get it checked out (also if he has a lump or pain in a breast).
This is something that isn't really talked about and should be. Breast cancer is not common in men, but it does occur. I work in Pathology and whenever we have a male (by birth) diagnosis of breast cancer, there is a lot of confusion from the patient because they didn't realize it could happen.
Load More Replies...I wonder, does it work the same for babies as breast milk? Purely random thought.
I mean, sure. There are men who have breast fed. It IS breastmilk. My only concern about the stuff the concentration camp survivors were producing would be an overload of stress hormones in the milk. Like cortisol, which is a known problem in distressed mothers.
Load More Replies..."it's more common than you think most men are just too ashamed to admit it" really? Most men are not ashamed they don't even know this
It’s not saying men are ashamed in general. It’s saying men who lactate might be too ashamed to report it is happening. There are psych meds that can cause men to lactate and they might be too embarrassed to mention it to their psychiatrist
Load More Replies...Our then new born daughter was lactating and we were really confused. But it just happens
This is due to the residual affect of the mother's hormones and yes, it happens.

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.
This should be how people should've been made to stay at home during covid...
That's why I hang out with successful people - you are what you eat. (This far this has been a fruitless endeavor, but they generally have better snacks than me so I'll keep trying...)
I'm very allergic to housedust, so I'm not lying when I say I'm allergic to people. For reals.
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
I swear I've read something about this before. Don't quote me but maybe something to do with the guillotine beheadings?
Load More Replies...I call BS on this one. Yes the muscles of the face and eyes etc will have enough oxygen for the head to look animated briefly after decapitation, but the catastrophic and near instantaneous loss of blood pressure to the brain means unconsciousness, not awareness.
"Alive" maybe but conscious, probably not. The sudden and massive drop in blood pressure would render you unconscious. Heck I even get black outs just standing up.
One time my dad stood up too fast and fell down a flight of stairs and broke his toe
Load More Replies...I researched about this - do you still retain consciousness when you become decapitated? Because surely your brain doesn’t realise straight away right? I read loads of interesting stuff, I recommend you check it out
France used the Guillotine for capital punishment until the 70s with detailed descriptions. Also, beheading was a common method of punishment for hundreds of years with many, many, many detailed accounts by witnesses and the Heads men themselves.
They probably wish they still had the organs to cuss someone out
Most humane, non-suffering way to die back then
Load More Replies...no because they have no lungs. they could glare at you tho
Load More Replies...I mean, it makes sense...Much of your body is life support for the brain. Short of destruction of the brain itself, the quickest way the brain dies is lack of oxygen. We dont die instantly if we hold our breath, so the brain can survive a very short while without it.If you think about it, many causes of death are essentially lack of oxygen to the brain.
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
I knew this! There was a super famous saxophone player a few years back that had to get brain surgery or something and the surgeons had him play his saxophone during the procedure so they knew they didn't mess up.
Shoutout to those surgeons performing one of the most complex medical procedures of all times while someone's playing the saxophone, meanwhile I forget where I'm going when someone at work plays phone music very quietly.
Load More Replies...My stepdad died of brain cancer but one of the weirdest parts of it was that he didn't feel any pain for 2 years until the tumors reached a size where his brain started pushing on his skull. Only the skull pushing actually hurt. It's weird to think you can have life threatening tumors and feel nothing
And it can be important to talk to the patient in brain surgery so they know if they’re pressing on the right bits!
Rosemary Kennedy was talking and singing during her lobotomy. Only when she stopped, did they stop cutting.
This was my first thought. Glad someone else thought it also.
Load More Replies...But doesn't the skin and stuff that you have to cut through to get to the brain have pain receptors, though?
They use topical anesthetic on that part. It's actually the pressure against the muscles, skin, and bone in the skull that makes it hurt.
Load More Replies...My husband went through that. He is a talented Organist and Pianist. Phd in Performance. First open brain awake surgery in Austin at that particular hospital. They stimulated areas of his brain to try not to affect his motor skills during tumor removal. He was given pain killers for cutting through the scalp and anesthesia but not enough to put him out. Just to relax him so he would not freak out with his head open. He had a doctor talking to him keeping him calm the whole time. His motor skills are intact but his math skills and short term memory were lost. He still plays very complicated pieces from long term memory beautifully. But has no clue about a bank account and forgets conversations mid sentence. And the surgery was not that long ago. About 10 years.
That kind of short term memory loss sounds very difficult to live with but better than losing him to the tumour. I hope you have many more good years together.
Load More Replies...But the skin and tissue surrounding the brain has pain receptors right? Or is Dr Mike wrong in that one 911 reaction video?
Yes the patient gets local anesthesia in the scalp and skull.
Load More Replies...and yet, it's the brain that tells us we're in pain, interesting
The famous Hungarian author and humorist, Frigyes Karinthy, wrote an autobiographical book when he found out he had brain tumor. It's called "A journey round my skull". He was operated around 1936 and he was awake during the surgery and shared a lot of details about how it felt. It's a great read, and I heard it was in the curriculum in some medical schools for a while.
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.
I dunno. I worked in a maternity ward for a while, and the shout of 'JUST GET IT OUT!' was heard more than once.
Load More Replies...I had two kids w/o painkillers but at NO point did I think a chainsaw near my pelvic bone would be a good idea.
I had two kids by having my abdomen gutted and I still don’t think a chainsaw near my pelvic bone would be a good idea.
Load More Replies...If I am not wrong, another consequence of this was that human babies also evolved paralelly to be born much more "prematurely" to fit the narrow birth cannal. Human babies are born totally defenseless and underdeveloped. They are dependent to their mothers for longer time than the babies of other mammals that are able to move a bit or hold onto their mothers or some even can run not so long after birth.
It’s more like: Women who tended to give birth at an earlier point in gestation were selected for (in the evolutionary sense), and their counterparts who give birth once the baby is too large to pass the opening were selected against, which I know sounds wildly pedantic, but evolution never actually makes any choices or coordinates things so neatly because it has no agency, it cannot actually deliberate. Even scientists who know perfectly well how it works also make use of verbiage that invokes the ghost of an agent. They say things like “giraffes grew longer necks to get at higher leaves”, which, grammatically, makes it sound like giraffes got together to deal with that high-leaf situation. They obviously didn’t do that. The ones that had slightly longer necks got slightly better fed and were slightly more fit during the mating season, so had a better chance of passing on their long-neck genes. Evolution is just a way to talk about a certain kind of statistics.
Load More Replies...Hell, mine did, and I don't even have one!
Load More Replies...It's called the "obstetrical dilemma", and, in evolutionary terms, it's only getting worse. The human cranium is still on a path toward enlarging, and the pelvis can only be so wide while still functioning for bipedal locomotion. We are creeping toward an impasse.
Yups. Women have pelvic spreading which helps to a degree, but it's also why younger girls/teens are at a higher risk for giving birth so young because the spread just doesn't help them. Big, oversized babies are a problem too.
Load More Replies...Yes, I was just reading about it recently..... my female partner freaked out a bit when I told her :-)
Load More Replies...So how cutting your bone with a chainsaw is less painful than birthing a child? I don't think they had anesthesia at that time either...
It wasn't about pain, it was about getting out a stuck baby
Load More Replies...This process is known as SYMPHYSIOTOMY and for many years, sawing through pubic ligaments/cartilage and, more rarely bone, was used in Ireland as an alternative to Caesarean. Over 1,500 women in Ireland between 1944 and 1987 were given this torment without their informed consent. The procedure will leave you unable to walk, pee, poo, or give birth again, depending. It doesn't use a chainsaw. Just a medical bone saw. Also, this torture was first advocated (by a man) in 1597. Rather than call a midwife to turn a breech baby or similar, the man just got to sawing.l.. without care for consequences for the woman. It's been used across Europe and Africa, and people as recently as the 2010s still advocated for its use over caesarean section. Source: WHO, UN Committe Against Torture, and Irish Examiner. (My ucnle by marriage is born Ireland, his aunt had one done, so that's how I heard about it)
I'm feeling a little faint now especially the recency
Load More Replies...And some people still think getting kicked in crotch is more painful.
Sometimes when you have a runny nose, it isn't snot. It's cerebral fluid that the brain leaks to reduce pressure.
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.
I recently read a story about a UK woman who has CSF leaks and for some like her, it can be really debilitating. The trouble is usually in finding the leak, for those who have problems because theirs don't heal, etc. She was treated a couple times with some kind of blood clot therapy I think it was, but she's still suffering from it (more leaks). The only time she feels any relief from symptoms is to be laying down horizontal so it's pretty much wrecked her, unfortunately.
Load More Replies...This is usually also accompanied by a bad headache that is relieved by lying down. Unfortunately common in people like me who have connective tissue problems and rarely diagnosed in a reasonable amount of time. Lots of doctors telling people with CSF leaks to stop overreacting before they finally find it.
This happened to my aunt. She had a small tear in the membrane around her brain. Had surgery to repair it.
Sometimes during brain surgery, they'll peel your face forward like a goddamn banana.
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.
i wouldn't mind scaring children, but i would not be able to function if I scared small animals.
Load More Replies...Have had this experience. I was born with a cranial deformity (craniosynostosis- specifically trigonocephaly or a triangular shaped skull). I have a large scar running across the top of my head from one ear to the other ear.
I had it done twice for surgery to patch bilateral semicircular canal dehiscence (holes in my skull that let my "brain juice" get in my ear canals). "Being peeled like a banana" was exactly how my surgeon at the Mayo Clinic described how he would get to the area that needed to be patched.
You prefer they peel like an orange? If it can peel, it'll heal. My mom's face was peeled like that, she's fine. Deal with it. And it's only the forehead they peel, not the whole face, FFS....
Yes it’s true. They even have tiny clips to hold it down so it won’t go flapping back. This is common for certain plastic surgeries…facelifts etc.

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.
1. EXACTLY 67? 2. Surgeons clean nothing besides their own hands.
I had an invasive foot surgery three days ago and NOBODY cleaned my bellybutton out for me! I feel ripped off and I demand to speak to a manager this instant!
I'm surprised navel piercings don't get infected at an alarming rate if this is true.
Happened to me. I wasn't even intended on getting pierced but went with my then boyfriend to get his done and got talked into it. The damn thing kept getting caught on my clothes but also infection after infection despite cleaning twice a day. Just took it out and it healed easily. My body was clearly like WTF, and just wanted it out.

What about eye surgery and other facial surgery (I've had several) what would be the point then?
eye surgery is awful. It takes longer to recover than any other surgery
Load More Replies...Where I come from, the hardcore fluff is first removed from the patient's navel with so-called surgical tweezers, which is what we call the bare thumb and forefinger, and the evacuated samples are archived according to odor notes and previously validated nasally by the microbiologist on duty. Finally, the samples are launched with an AmazonPrime rocket to Elon Musk's research package station on his private planet "Fullpost I".
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.
Oh god, this happened to my mom, as well. It was a nightmare for all involved. Trying to explain Kegel exercises to a woman in her 70s (who is also your mother) was… not fun. I had no luck explaining to her which muscles to work. My family has very few personal boundaries (no banjo music type stuff though, thank you) and I was nearly ready to have her put a finger up there OBGYN-exam style into my body and do a Kegel so she’d know what I was talking about. Though she probably still wouldn’t have understood how to flex the same muscle in her body. XD
Load More Replies...Uterine prolapse is most typical after childbirth or due to trauma of other natures, abnd you can be strong AF and still experrience it. Don't assume it's about her muscular strength. Pelvic floors are complicated networks of connective tissue and bone. .... MD (And, no, Kegels won't prevent it, but they reduce likelihood.)
Sometimes. Sometimes too many Kegels can cause painful s e x and/or incontinence. See a pelvic floor PT, people. Edit: stupid autocorrect
I’ve actually seen this when I was a nurse. Elderly ladies, their cervix was so fallen down it was visible. They used something called a pessary to deal with that. As much as I’ll write or everyone will be racing for the brain bleach.
It doesn't detach, just dangles. Want to reconsider?
Load More Replies...When I worked in a nursing home, this was a frequent issue for the cna’s . We would have to lift very tall men or use a hoyer lift for super obese patients. I lasted a few years but couldn’t hack it and the strain on my body. This was 25yrs ago and I hope things have changed but not enough staff to go around and I doubt it’s gotten much better.
Hmmm...do you mean a pessary? In America a f***y pack is basically a purse one wears around the waist to hold your wallet, keys, etc.
Load More Replies...Skin's still attached. It's called a prolapse.
Load More Replies...This is the worst way of describing how uterine prolapse occurs that I have ever heard. Don’t do Kegels/pelvic floor exercise until you are and adult (well into your 20’s) or are pregnant and don’t do more then suggested. Too much and too soon can screw things up just as much as not enough.
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?
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
My friend has their discord status as 'breathing now set to manual' and it f***s me up every time I see it
Load More Replies...With a stuffed nose and I can confirm, the stuffiness changes nostrils every few hours
Breathing in through the left nostril is an exercise for calming and also cooling down. Breath in through the left nostril while you have the right covered and exhale through the right while you have the left covered. Do this for 5 to 10 cycles then switch. The left nostril activates the parasympathetic nervous system, it's science!
That's extremely helpful, Narwhal Blast! Anything that helps to relax is something many people need. Also, fu.ck you CII. Nobody asked for your snarky comments either, you douche conoe
Load More Replies...so when i can’t breathe during a cold is bc my other nostril that’s SUPPOSED to breathing for me is blocked full of SNOT
Best thing I've ever found for my nose/sinuses with a cold, is using a saline solution spray. The non-habit forming kind. The salt water pulls excess moisture out of swollen sinus cavities to make them shrink. The trick I found was to not move for as long as I could, after I sprayed into each nostril. Keep your head straight, don't tip it back (or it'll run down your throat) and don't tip it forward (or your nose will run). Don't sniff, or snort, or do anything except to dry the inside of your nose with a tissue. Keep still for a few minutes, let the solution sit and do its thing. This can be hard to do, but the payoff is worth it. After those few minutes, feel free to sniff/snort/swallow, or blow your nose.
Load More Replies...I had a decades long sinus infection (never diagnosed until decades later!) and finally had it cleared out surgically. Breathing through the nose is loud! It took a bit to get used to the loud noise as I breathed through my nose fully in decades! Our brains usually filter out unnecessary stimuli.
Yeah brain filtering is so col but strange, like how we "see" our noses but the brain just blocks that out as useless info.
Load More Replies...also: did you know there is no place in your closed mouth your tongue rests comfortably. It just hangs in there
There is a yoga exercise in which you have to breath just through one nostril. I always thought it would just be a focus thing
It's supposed to be more than just a focus thing if you get into the actual philosophy of it. It has to do with the movement of energy (prana) throughout the body.

You produce more earwax when you're stressed and stressed earwax smells way worse than the regular stuff

Load More Replies...My BO smells different when I'm stressed, at least according to myself. But what I really want to know is why humans are so attuned to the way dogs smell when they're stressed out. I 100% know what that smells like, and when I ask people, a lot of them know what I'm talking about. I want to know why dogs smell so strongly to humans in general. Was there some kind of advantage to this in the past?
We’ve evolved alongside dogs for some 30,000 years now. They used to be valuable “tools” (hunting, herding, guarding, etc) that humans relied on to help them survive. Perhaps it evolved along the way so humans could identify when their valuable canine companions were stressed, so the humans could help them before it progressed to illness/sickness or death? That’s total conjecture on my part XD
Load More Replies...Cortisol makes *everything* smell worse - sweat, discharge, breath, etc. Take time to destress, folks! And don't be afraid to stop and relax for a while! Humans were never meant to live such overburdened lives the way so many of us do these days.

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.
My one relative had this happen to him, he’s now blind in one eye
Immune System: THERES SOMETHING ATTACKING YOU Me: No those are my eyes Immune System: YOUR EYES ARE ATTACKING YOU? Me: No- Immune System: CALL THE POLICE
Allergies are also the immune system thinking totally benign substances are dangerous (like poisons). And this can be triggered in all kinds of ways. Ther is even something (a disease I think) that can make you allergic to meat
Alpha-gal syndrome. My uncle caught it from a tick bite. He can only eat fish and poultry now. Any red meat sends him into anaphylaxis and he needs an epi pen. Except venison, for some reason. He can still eat that. Even the doctors don't know why.
Load More Replies...Our eyes have their own immune system, at any moment our bodies immune system can attack our eyes for literally no reason, pretty bad design.
So horrific and heart breaking, something like this can happen when you have cancer. Your immune system, which is trying to kill the cancer cells, goes haywire and interprets your brain as foreign thing in your body that needs to be destroyed. And it does. Seen that too. I’ll never forget her or her family. My heart is aching right now just writing this.
Yes and the eyeball can actually rupture as discovered by my family member. Best kee up with annual eye checks to make sure this doesn't happen.
It is called that, but no, your brain shares its blood supply with the rest of your body.
Load More Replies...I have one of those diseases. It's called Sjogren's. My immune system doesn't only attack my eye but can be diagnosed or suspected due to the eye damage the disease causes. Sjogren's attacks the moisture producing glands in the body and eyes are heavily reliant on moisture to stay healthy. As a result, I have extremely dry eyes that affect my vision. Some with advanced disease aren't able to cry.
There could be mites having sex on your eyelashes right now you would have no way of knowing
Why are they doing this infront of my eyes? They should feel ashamed of themselves. Go away, get a room somewhere. No... Not in my ear canals! I do not want to hear sex noises either.
Probably less disgusting to us than what our hotel/motel bed could tell us.
Not just ON your eyelashes, but inside the follicles themselves. All over your body, for that matter. It's symbiosis, where they're actually a huge help and not a hindrance. The theory is that they evolved this way because they're definitely lazy little sods.
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.
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.
I have this and it's because some scar tissue in my eye was shrinking and pulling on my retina. I had surgery to separate the scar tissue from my retina but the damage was done. It kept me from going blind in that eye though. I hope they can help you and improve your vision. Best wishes
Load More Replies...I don’t see it as lying. I think it’s just like “ok this is the best I can do with that the eyes gave me. It looks like a purple giraffe on top of a purple… couch? I want to say couch. Anyway give that to the clever part of the brain, they’ll work it out. Whatever you do don’t give it to the amygdala or he’ll go ape sh!t.”
Also, your brain filters out your nose unless you're actively thinking about trying to see it. In theory, there could be an entire alternate universe right in front of us, but our brains filter it out because it's deemed unimportant or distracting
Hold up, is it saying if you cover one eye you don't see a black void to that side....I do see that in my periphery unless I move the open eye in that direction to cover that field of view. I also always see my nose and the frame of my glasses and never forget they're there. The thing is though, I'm autistic, and I have a really sensitive sensory system and just do not filter out some of the things others do.
I don't see my nose but I do see the rim of my glasses and I am not autistic (to my knowledge). I was prescribed glasses back in 2012 and have only ever used rimless ones because the first one had thick black frame and could help but see the world in that frame ALL the time, it was irritating and gave me headache.
Load More Replies...There's a syndrome called 'Charles Bonnet' where (usually in elderly blind) the brain 'makes up' the missing background, often with weird hallucinations - seeing the postman as a cartoon roadrunner for instance. The people know they're hallucinating, so usually aren't worried and are used to it....so sometimes don't report it to their medical team.
This is also why (I think) it doesn't bother you to turn your head while looking forward but it usually DOES bother you if you are watching a video and the video camera suddenly pans right or moves around a lot. When you do it yourself your brain is ready for it / knows about it but when you are just sitting in a chair staring forward the brain has no warning the image is going to suddenly change.
The older I get, the more certain I am that no human can ever actually know for certain what is real and what is not... At first it was monumentally disturbing but now I actually find it comforting because I finally have a real reason to always have a background level of idgaf
Load More Replies...This is why eyewitness testimony is so very unreliable as evidence when it comes to criminal court proceedings. Ask 10 people about an event they all witnessed and you'll get 10 different answers. Our memories aren't nearly as reliable as we believe them to be.
Not only are our memories often unreliable, we often "see" what we expect to see.

The water you drink has probably been inside someone or something else.
Probably? Nah, definitely. This is the same water that's been on our planet since way before the dinosaurs (edit: it was a typo, please be nice)
Yups, our water is essentially "space water", since all of it got here through the cosmic bombardment of Earth in the very early days, and some through chemical reactions. Besides all the rock and metal, water is as old as the Earth almost.

When you die, your body will begin digesting itself as enzymes eat through cell membranes and leak out.
I mean, sure, why not. Make those nutrients available to whatever needs them right now, I certainly don't need them anymore. Eat me, I don't mind!
This is why I want a green burial. Eat me Earth!

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.
I vaguely remember reading that if you regularly exchange bodily fluids with a partner your body will actually tolerate their cells and they can be used as a donor for certain things.
I remember reading that too, but I forget what study it was.

According to research, the intestinal bacteria can also be more similar in couples who have been together for a long time than in identical twins.
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.

He's a disgusting idiot indeed, sorry. Holding a bit of tissue or a thin piece of cotton in front of your mouth and nose when you sneeze won't hurt and definitely won't make the eyes pop out!
Load More Replies...My cat will sneeze directly into my face and then look at me like *I* was bothering *HIM*.
I sneeze really hard and I'm sometimes amazed at what the sound wave from it can do. Examples: Standing by my mother's piano in a quiet living room. I sneezed about 5 feet away from the piano and I could hear the strings echoing inside the piano. I've also heard it ping off the metal of my treadmill about 5 feet away as if something had lightly tapped. it. I don't get it really. Kind of weird but has been that way since I can remember.
I had a friend tell me that if you sneeze with your eyes open, they'll pop out👁
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.

One of my teenage neighbors (14 M) is autistic and struggles with social and general anxiety. He became a big fan of Mobile Gundam Wing (the anime) last year, and was telling me the other morning that it changed his life. When I asked him how, he said something along the lines of, thinking about his body as a "mech suit" and himself/his brain, as the "owner/operator". In his thinking, this helps to put a "barrier" between himself and his perception of other people, and theirs of him, which helps to calm his anxiety. Sweet kid, and it seems to be helping him, because he'd never done more than just wave at me whenever he saw me, but that day (I was bringing in my garbage can while he was walking to the bus stop at the corner) he stopped and talked to me.
Load More Replies...As addressed in the vision post here, I find it freaky that you are your brain, but your brain can lie to you - editing your vision, burying traumatic memories - its an existential rabbit hole.
It actively edits your perceptions of reality on a much deeper level than just your vision. Numerous experiments have demonstrated that the brain has a definitive preference for cause/effect and pattern recognition. Basically, your experience of reality is your brain's best prediction of what the world outside your body is like and will be like in the immediate future.
Load More Replies...Not necessarily true. We don't know for sure where the "mind" ends or begins. organs may even contain memories. There are a lot of stories where organ donor recipients end up having similar tastes to their donor and remembering things they never did.
I feel like I finally know myself now. I'm a three pound wrinkly thing. How individualistic (if that's even a word).
Ok then, separate the brain and the body and see how long they work without each other
Also you are two persons that are just in sync with each other. look it up. XD
I find this nonsense. I am a brain in a body, that means that the whole thing IS me.
you are the soul who activate the brain to control the body... At least I am
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.
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.
I call b******t. https://www.ctvnews.ca/health/why-do-women-eat-their-own-placentas-canadian-study-seeks-to-find-out-1.4239432?cache=fbvfbdkpstrm "The study’s authors acknowledged there was most likely an “overestimate” of women who ate their own placenta in their findings because they sought mothers in social media parenting groups."
Agree, there's no way a quarter of all women are eating those. Imagine people taking home doggy bags of placenta from the hospital. Absolute shite.
Load More Replies...That's disgusting and I don't care what excuses people come up with to do it....it's still f*cking gross.
Take my upvote please. Ive expelled a lot of things from my body, just because they are "natural" doesn't mean they're edible.
Load More Replies...Wow, so much misinformation in these comments. Yes, placentophagy is fairly common nowadays. It started among "natural" or "crunchy" communities, but you would honestly be surprised. I get clients from all walks of life who want to know more about it. The placenta is almost always dehydrated, combined with herbs and put into capsules. It’s taken to reduce postpartum depression and increase milk supply through ingestion of hormones remaining in the placenta. There haven’t been wide scale studies, so no hard data yet, but preliminary studies have been done to get the ball rolling. However, anecdotal evidence - particularly for reducing depression - is very high. It's possible that it's placebo effect, but since the risk appears to be very low (if prepared properly), and the depression rate is astronomically high right now, most birth professionals are in favor of whatever we can do to lower it. Also, you can still bank cord blood. And you use a cooler, not a doggy bag. Geez.
As humans are one of the only mammal species that does not regularly eat the placenta, it appears that there is no evolutionary advantage in doing so. The fad for eating the placenta is just that, a modern fad with no scientific backing or principle behind it. It does make some people richer though, so I guess that's why it persists.
Load More Replies...There have been concerns regarding the placenta containing infection, in particular group B strep. I recall reading of an infant who contracted the infection a few times (seriously ill) before they figured out the source.
How was the infant getting the infection when it was the mother having the placenta? It’s extremely unlikely to pass through breastmilk unless it’s expressed breastmilk that become contaminated (which was the case in the articles I read, so didn’t really have anything to do with the placenta eating).
Load More Replies...This is why I kinda hate any 'study' because the samples sizes are usually the favourable audience not the general public
I feel like they did this study in the hospital about half an hour after birth and the moms thought they had asked if they had eaten their chicken broth.
Im fairly certain the only reason some animals eat the placenta is to protect themselves and their offspring from predators who may smell the fresh birth. It doesn’t have much of any nutritional value
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%"

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.

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.
