Human bodies are weird and gross and wonderful things that more people should learn about considering, ya know, we're all in one.
So when one reddit user asked:
People showed up in droves to share their knowledge. Things were certainly interesting, but we honestly had no idea that our bodies were simultaneously independent machines capable of functioning in parameters we have no business being in (and doing so without our input most of the time) - and also really, really, reeeeaaaally crap design.
The acid in your stomach could burn your skin! I always thought that was pretty interesting, and reminds me of the scene in Alien, where the alien blood burns everything.
Which is why vomit feels so boiling hot
This is also why you produce a lot of saliva before vomiting - to protect the teeth and mouth from the acid
Intestines Work Themselves Outanimation wiggle GIF by xponentialdesign Giphy
Your intestines are constantly wriggling like worms or snakes and arrange themselves how they want to be. After abdominal surgery, doctors just stuff em back in and let them sort themselves out.
To be specific, they don't stuff it back willy nilly. There are some general rules, like this section goes here, and that one there. But the loops within those sections will arrange themselves since your intestines are attached to the back of your abdominal cavity through mesentery.
Looking Out For Mom
When pregnant, if a mother suffers a heart attack or other large physiological issue, the fetus will release a swarm of stem cells that move to the affected area, greatly helping in survival and healing.
Also the baby leaves a bit of its DNA in its mother which can manipulate her body for decades. It's called microchimerism.

Besides the genitalia, there are several parts in your body that can go through processes that can be classified as an erection, like nipples.
goosebumps are called piloerection and is just a bunch of erections in your hair follicles.
The tissues inside my right nostril are erect so much it is rare that I can breathe through that side. (It is a cleaning mechanism for the nose...just goes a bit haywire for me)
The clitoris also has erectile tissue. I know it's genitalia but a lot of people don't know that.
Hack Your Urine Stream
If you tickle just above your butt crack while you're peeing, it makes you pee more.
There's an explanation for this! It's called the anogenital reflex. Many baby animals (puppies, kittens, squirrels, etc.) rely on a parent stimulating the newborn's genitals (typically by licking), since they can't pee on their own yet. Orphaned animals in the care of humans require stimulation of the genitals with a warm wet Q-tip or something to get the job done. - tmlp59

You can determine the sex of a skeleton by looking at the pelvis and seeing if the pelvis looks like a Mickey Mouse head (female) or a reindeer head (male). It's funny, but it works surprisingly well in some cases.
It doesn't always work a 100% for prepubescent skeletons and pelvises that have in between markers, but it's still a fun trick.
So Much Extra
The laryngeal nerve starts in your brain and goes down into your larynx and controls what the larynx does (breathing, swallowing, voice box, etc.). So you'd think it's about 5-6 inches long, right?
Instead, the nerve travels down your neck, past your shoulders, wraps around an artery close to your heart, then travels back up to your larynx, adding and extra 15-20 inches of unnecessary length.
This same nerve is also present in giraffes, and also loops around the giraffe's heart as shown in this giraffe dissection video. This 2m long, doubled-up nerve's beginning and end points are a hands' width apart. There's so much extra and it's all useless.
Eyeballs Are Weird
Our eyes are super cool. You would think they all of the blood vessels going into the eye would be behind the photoreceptors, right? So that the blood vessels don't interfere with the light we're seeing? Well, it turns out, that's not the case. That's why we have a blind spot. Its where the blood vessels enter through the back of the eye, and then they spread out around the inside of the eye. So there's a whole bunch of blood vessels in the inside of our eyeballs, and that means that as light enters the eye through the pupil, a shadow of the blood vessels gets cast onto the photoreceptors in the back of the eye. Normally, our brain does a great job of photoshopping these out. But under the other conditions, it's actually possible to see those blood vessels.
But it gets even weirder. The blood vessels in the eye are so incredibly tiny that blood actually flows through them in a single-file line, one blood cell at a time. The plasma and the red blood cells, which make up the vast majority of blood, pass by completely invisible. But the other 1% of our blood, the white blood cells, can on rare occasions actually be seen! Once again, it requires pretty specific circumstances, most importantly a uniform field of blue light. And it just so happens that the sky on a clear day is the perfect shade of blue to see the blue field entoptic phenomenon.
If you were to stretch out the entire surface area of your lungs, they would cover a tennis court.
I found this out because I was searching Google for the typical size of a tennis court and one of the suggested searches was something like "are your lungs as big as a tennis court?" and I was extremely confused for a moment.
Human breast milk adapts it's nutritious content to fit the need of the offspring. Baby lacks iron? Next dose of milk will contain more iron. It's amazing.
Breast milk is SO cool!! There's a reason why it's called liquid gold!
More fun facts:
1- breast milk can be dripped into babies eye/ear/nose to treat infections (as mentioned by someone below, it works best as an anti-inflammatory, which can help! Also, it's more of a preventative than a cure.)
2- breast milk does change depending on babies needs and as they grow
3- breast milk contents differ depending on babies gender
5- it works on mild eczema!
6- the components of breast milk could lead to treatment for cancers! possibilities still under trial
7- it's "made" out of the mother's blood". "Milk is made inside glands from the blood stream. Breast milk is NOT made from the mother's stomach contents. The foods mom eats are broken down in the digestive system. Blood reaches the milk glands where it delivers carbohydrates, nutrients, white blood cells, enzymes, pro- and pre-biotics water, fat, and proteins into the gland." link!
8- mothers can detect issues with the baby through all of that kissing, which tells her body what to produce (like more antibodies etc) whoa!
Edit: you should of course always take your little to a doctor with any issues. These are "fun facts" guys! They should not replace any medical advice from a doctor. As I quoted somewhere below "However, the use of breast milk in treatment is not applicable in all cases. It should rather serve as complementary therapy, and not the only mode of treatment. At our present level of knowledge, non-nutritional uses of breast milk are certainly better suited to prevention than to a medicated process. "

When we go to sleep, we slip into one of the most vulnerable positions we can possibly embody. And we do that every single day.
So it's hardly surprising that, at least a few times throughout our lives--maybe more than a few--we find ourselves snatched from slumber, and left sitting started and defenseless against a threat we can barely make out in those first few seconds.
But for all the vagueness of those first few sensations, we sure do remember those horrible awakenings rather vividly.
And recently, some folks on the internet shared their most memorable experiences.
Redditor ScoopySnacks829 asked:
"What's the worst thing you woke up to?"
Many Redditors encountered animals in the dead of night. The creepy crawling hands and mouths were enough to make their skin crawl.
"My grandmother had a filthy house and made me and my brother sleep on the floor whenever we were over."
"Once I woke up with a rat tangled in my waist length hair. I was 8"
"Another time I woke up to see a giant roach crawl. Out of my brother's mouth as he was sleeping. (I never told him as I figured he would rather live in blissful ignorance.) I was 9."
"To this day have a fear of Rats, roaches, and sleeping on floors."
"A dog's paw in my mouth and getting stepped on the balls at the same time" -- Lower_Environment774
Only Thin Nylon Between You and It
"The sound of a bear outside my tent. Got my heart racing." -- SingLikeTinaTurner
"Oh fu** okay, so I once was woken up by a bear paw to the head. It was just fu**ing around with our tarp but I'm tall so the top of my head stuck out just a tad. It felt like being brained with a sandbag."
"It was a black bear and ran off when we made a bunch of noise, but I'll never forget the few moments of sheer terror, head reeling and seeing that bear paw slide next to my face." -- Cthulhu_sneeze
"Blood all over the bed that I was in. Then I saw the flyscreen had been torn open. Then I heard a crunching noise. And then I saw the cat with the remains of a magpie."
Others shared the times they encountered a personal tragedy immediately upon waking up in the morning.
"woke up to the news one of my best friends family had been murdered in an arson attack and that he had tried to save them and had 3rd degree burns over 70% of his body..."
"I woke up to my dad telling me my mom had a brain tumor."
"It was during a sleepover with my best friend at the time. I knew they were going to get her an MRI because she had been having really bad chronic headaches, but none of us expected brain cancer."
"When they removed the tumor two weeks later they removed a baseball and a half sized mass of tumor from her right frontal lobe. She's alive and well now 15 years later, thank god, but that was an awful time for everyone in our family."
The Worst Reason to Get Up and Go
"My uncle calling me in the middle of the night to tell me my mom was in the hospital, and that I should fly out as soon as possible if I wanted to be able to say goodbye."
Finally, some people discussed the times they felt threatened by other human beings that clearly did not have their best interests at heart.
Just What Did They Want
"Someone jiggling the handle on my door, trying to get in to my apartment. Scary as fu**. I don't know if he was drunk and thought it was a different apartment, or if he was just going door to door, seeing if any were unlocked."
"My ex-girlfriend pointing an unloaded gun (I thought it was loaded) at me. She pulled the trigger and she wanted to scare me, she thought I was cheating on her with a friend of mine (a female)."
It Gets Worse and Worse
"When I was like 16, the landlord and a couple of other men (LEOs of some sort, presumably, but I didn't get a good look at them) came in to physically evict my mother and I from the duplex we lived in at the time, something I had no idea was in at all."
"Like, we apparently went through the entire eviction process without me getting even a slight sniff of it. I slept naked even back then, so basically, I was awakened by two or three strange men coming into my bedroom."
"I threw on a cream-colored dress and got the fu** out of there, having no other option obviously, and went to my mother's workplace in a panic...where one of her coworkers gently pointed out that I had started my period, which was obvious from a distance, apparently."
Here's hoping this list won't give you trouble falling to sleep tonight.

Simply put, the line between needs and desires becomes blurry without us even realizing it.
That is, until we look at our bank statement at the end of the month, suppressing the tears and horrified shrieks that want to leap out of us.
But with the help of a recent Reddit thread, perhaps there is hope. Maybe taking stock of exactly which unnecessary places that money is going can help us dial it in.
Redditor Rice_Liar asked:
"What is the biggest waste of money?"
Of course, many people mentioned the common vices that have long been dubbed the easiest way to throw your earnings right down the tubes.
The Next One Will Hit, I Know It
"Scratch off lottery tickets. I visited my uncle, and he asked me to help him sort the scratch tickets he had bought that year (I guess if you collected enough non-winning ones you could turn them in for a small prize?). He had stacks and stacks of tickets. Took us forever to sort them."
"He was proudly telling me about the times he'd won 50 or 100 bucks, but it clearly didn't even begin to break even with the total amount he paid for them."
"I still buy one every once in a while for fun, and know that a lot of people enjoy the thrill of them and don't mind spending a few dollars for it, but seeing how many he had with no worthwhile return except a rare win has definitely stuck with me."
"I just quit smoking and I have to say tobacco, in the Netherlands the pack of tobacco I used to smoke (John player special) costs 14,40 euros or $16.95 dollars according to google u pay that much multiple times a week for something that kills you."
"Any smokers here wanting to quit but can't, just buy a vape pen it makes it so much easier."
Designed to Fail
"Gambling. Most of the time it goes tits up and has ramifications for other people in your life." -- Mgreengo
"Worked at a casino. I saw behind the curtain. You will lose. The only way to win is to accidentally win a jackpot (that you somehow didn't spend over the jackpot amount to win) and walk away never to return." -- Femmefatele
Others discussed those unneeded luxuries that we get lulled into thinking we absolutely need.
For Olympians Only
"buying a house with a swimming pool. Unless you're an avid swimmer, you'll only use it irregularly 2-3 months a year. Requires constant maintenance that cost up to 5k a year."
"If you build the swimming pool after you've bought the house, that's around 30k for a 600 sq2 ft pool. And it most likely will not increase your house' price at all."
"Stupidly expensive weddings" -- FairySpice12
"Napkins - $1"
"Baby Napkins -$5"
"Wedding Napkins- $20" -- OntarioIsPain
How Did They Do That?
"Starbucks. $6 for an iced coffee that usually isn't that great." -- kdub1523
"The $6 'coffees' are usually a drink with a million things added so it doesn't taste like a coffee" -- Main-Argument-5898
And many people took notice of all the money they spend on transactions surrounding our online lives and our relationships to all the new gadgets that make our heads spin.
Monthly Black Holes
"Subscriptions to stuff you don't use anymore." -- StructureMoist
"I feel like you don't need all the streaming services. For me, I have netflix, prime, Disney and Spotify. I pay for prime and Spotify and my boyfriend has Disney and netflix. We share the accounts. I use all of them about about same amount, Spotify the least but I miss it a ton when I don't have it." -- Zanki
Money From An Unseen Source
"Donating to popular streamers they have so much money and they are most likely to not read your donation" -- fiskars12345
"I much prefer to give my money to smaller streamers because they're always so sweet and I like supporting them" -- mintmoonstone
Give It a Few Years
"Latest mobile phones every year with allegedly 'revolutionary' must have new features!" -- MarcDarcy
"I generally skip 3 or 4 generations. Then buy a new phone after I've wrung every last ounce of life out of the old one." -- Majik_Sheff
But It Seemed So Fun For Those Few Seconds...
"buying video games that you'll never play" -- Zack4044
"But it was 75% off, how could I pass up those savings" -- 98raider
"There goes my angry upvote of the day." -- Nidrew
So maybe it's time to face the harsh realities of the monthly statement and see where the big omissions can be.

You've probably stayed up late watching some television special about a criminal in your area and seen the announcement near the end: "If you have any information, call our tipline." The authorities might even offer a reward of some kind. But what are the chances that you might actually know of the person they're looking for?
People shared their stories after Redditor Renzot56 asked the online community,
"Has anyone here ever actually called into one of the FBI rewards for information on criminals and won the money?"
"My neighbor down the road..."
"My neighbor down the road growing up was always getting into trouble. One day someone robbed a gas station with a gun, and accidentally shot the clerk (so he claimed), and the police didn't know who did it. After about a month, they offered up a small reward for information. The guy arranged to have his wife turn him in to collect the reward, because she would need it since he knew he was going away for a long time."
A likely story!
"I felt pretty good..."
"Ten years ago I'm working front desk at this third rate motel and I'm the only employee on property until 7am.
So I get this report of an unruly guest and check it out. Dudes whacked out on something, threatening other guests and I call the cops to remove him. On their way out they tell me he's got active warrants in another state.
I don't think anything of until three months later I got a check sent to me at work from a sheriff's office two states over. Turns out the guy was wanted for a double murder and I got the reward when he was convicted. I felt pretty good about that."
"My sister has a pretty weird hobby - she solves cold cases by helping match descriptions of bodies that have never been positively ID'd to missing persons matching the body's description. She's solved several cases and submits them to the FBI tip line. Twice now, she's gotten phone calls from law enforcement as a result, one from the FBI and one from a local police department. One had reward money tied to it from long, long ago. She turned it down.
Both times, she's informed the agency calling that the missing person disappeared before she was 10 years old (that's her limit, she doesn't look at recent cases to avoid potential problems), and they just kinda shrug and move on. That's all."
I think I'd be pretty proud if I had Nancy Drew as a sister. Well done!
"I made an anonymous tip..."
"I made an anonymous tip to a local library about someone posting online about wanting to do something sexual in the bathroom of the library.
Local police and FBI gave me a call on my actual number (not the one I used to call in the tip) and asked me a few questions.
Turns out they set up a raid and caught some 19-year old who was trying to meet kids online. Got $500 and they offered to pay me to go on apps/websites like Craigslist and such to find the same kind of people. Was pretty cool."
I'm sure that child's parents were rermarkably grateful.
"In college, we had a drive-by shooting on my block. The police showed up and asked all the neighbors if they had any information. I had just heard the shots from my house and wasn't able to help.
A few days later I was walking home from class and I found a shell casing the in the grass near where the shooting was. I didn't want to touch it so I got home and called the police. I was very very specific about exactly where the shell casing was, and that I DO NOT want the police to come to my door. The neighbors were pretty sketchy people and I just didn't want to be seen being involved.
Well, these cops walked right to my door and asked for me. I told them exactly where to find it (again), they walked to the general area, looked for maybe a minute, then walked back to my front door and asked if I could show where it was. Goddamit. So I led them to shell casing while the sketchy neighbors stood on their porch and watched (looking very displeased).
Apparently, the fingerprints on the casing matched one of their suspects and he was arrested and went to jail. The cops stopped by a few months later with a $20 gift card to a sub shop."
All that for $20?
"When living in Minneapolis..."
"When living in Minneapolis, I saw a Craigslist ad looking for a roommate that specifically worked at Minneapolis-St. Paul international airport and had a badge that allowed them to access beyond security.
I alerted the FBI and Minneapolis police through their tip line. Never heard from either of them."
"I'm sure a bunch of people..."
"I called CrimeStoppers once. The local news released a video of someone violently robbing a store. They beat up the cashier pretty badly.
I knew it the second the video started who it was—a guy I used to party with and had spent the night with a few times.
The CrimeStopper folks gave me a number to write down to claim the money if he was convicted. I wrote it on my hand then washed it off accidentally like an idiot. It was on the smaller side, I think around $1k, but it would have made a big difference at the time. And the guy did end up getting convicted and is still in prison now.
I'm sure a bunch of people called in, though, so I don't know how much I would have gotten. Anyone who grew up in my area who was around my age would have known the guy."
A long time ago..."
"A long time ago, 20+ years, a nearby bank was robbed at gunpoint. The article had a very good photo of the guy. Turns out, he was my sketchy neighbor. Saw him that morning, he was still wearing what was shown in the photo.
Long story short, cops bust him, he goes away for a long hitch, they said a small reward is available. Told them to donate it to a nearby animal shelter. Everyone wins! Well, almost everyone."
The animals certainly won this one! Good for them.
"I've sent a few..."
"I've sent a few tips to the FBI over Internet fraud over the years and have never gotten anything other than an automated response and certainly no rewards."
The FBI might want to do something more than just leaving automated messages for their tip line. Who knows? The answer to some long-unsolved cases might be out there... just a phone call away.
Have some stories of your own? Feel free to tell us about them in the comments below!
Often, high school is where students become rebellious. They're learning about themselves, they're testing boundaries, and they realizing that they can break the rules and sometimes get away with it.
Sometimes they're doing it to mess with a teacher who's treating students unfairly, sometimes they're doing it because they're standing up for the very little autonomy we afford kids in the first place.
Redditor CloudWoww wanted to know about those moments that are unforgettable defiance of authority.
"What was the most legendary thing a student did at school?"
These stories will amaze you!
"My friend once was pissed off at the rest of us guys (5 of us). He chased us into the bathroom because he wanted to be a tough guy and thought one of us was hiding in a stall. He says 'peekaboo I see you!' And kicks the stall door in on a teacher we all knew, taking a crap. The teacher said, 'I see you too Nathan, now close the door.' I will die the day I forget about that lol."
"The teacher's response was legendary!"
"Agreed. Honestly, at that point, what else are you going to do? Invite them in for a cup of tea? Challenge them for the seat? Model the proper way to greet another on the toilet?"
"Teaching is great."
"This kid in my class put the school for sale on Craigslist. He provided the school's attendance office number as a point of contact because everyone hated the receptionist there. They were getting calls from interested buyers for days who wanted to buy a multiple acres of property with a big swimming pool and a track."
"Some kids put up Craigslist ads for free brand new TVs with my school's number listed as the contact and they received thousands of calls by like 10 AM. It was legendary."
A teacher with poor eyesight.
"My English teacher was close to retirement & had really poor eyesight."
"A mate started the lesson on the right side of the classroom & managed to shuffle both himself & his desk to the back of the room and then over to the left."
"He then managed to climb through the window, sauntered round the building, came back into the room & apologized for being late."
"Not even to leave, just to see if he could."
"Yeah, teachers who can't see properly can be pretty funny. I had a teacher like that. During that class, a classmate from our year had a free period and lived too far away from the school to realistically go home. But he had friends in that class, so he just came to that class."
"In the teacher's defense, it was a fairly big class, at least 25 kids, and the kid wasn't disruptive or anything. He didn't actually participate or anything, he just sat there and occasionally talked to his friends while they were working on tasks. It took the teacher several 'visits' to notice that 'visitor,' he seriously didn't notice for several lessons that there was a kid he didn't know."
Teaching the teacher a lesson.
"Teacher everyone hated just cause he was a pure bully. We had a fair snow fall and he was on yard 'patrol' this shy kid launched the perfect snowball 40ft+ and it went in his cup of juice. Splashing out and soaking him. Kid went from 0 to hero real quick! This was approx. 15 years ago and we still talk about it today when I'm with a friend from school."
"Kid is going places."
Someone lost their marbles.
"This kid once brought a backpack full, and I mean completely full of marbles to school. He went to the main staircase near the front up the third floor and dumped the whole bag over the stairwell. How those marbles didn't break the glass trophy case at the bottom is beyond me but marbles went everywhere. Surprisingly he never got caught. He either managed to run to one of the stairwells at the end of the hall and get to the bottom before teachers had time to react or he hid somewhere until the first bell rang."
"This happened back in like 2005. Kid went on to disgrace himself and be sentenced 16 years in prison for military espionage....so."
"Did he blame it on losing his marbles?"
The fire alarm.
"A kid hit the fire alarm when the mayor was visiting our school. For context, we had an assembly the week before where we were specifically told not to hit the fire alarm during the mayor's visit unless there was an actual fire, as it was a common occurrence at our school to just hit the fire alarm whenever."
"'Hey Bob, do you have any plans before school?'"
"'Hey Bill, yeah, I'm just going to pull the ol' fire alarm again.'"
"'I have a study hall around then, I'll pull the ol' alarm for you.'"
"We had a kid do this when our state's Supreme Court was doing a presentation or visiting or something. The staff was FURIOUS, everyone knew he did it, and they tried to prove it was him, saw LEOs dusting the handle for prints. There was an old rumor that when you pulled the handle it sprays like an invisible ink visible to black light on your hand, idk if that's true, but I know the kid used his shirt sleeve to cover his hand when he pulled it, so there weren't any prints."
"There was an old rumor that when you pulled the handle it sprays like an invisible ink visible to black light on your hand, idk if that's true."
"This is definitely not true."
"Source: I am a commercial fire alarm technician.
The rumor that we all believed to scare us as kids, turns out was just that: a rumor.
Senior prank that everyone loved.
"The senior prank one year was hiring a mariachi band to follow our principal around all day. He loved it--went classroom to classroom so everyone could see it and take pictures/videos and have a fun break from class."
"A señor prank?"
Standing up for what was right.
"A special needs kid got a two day in school suspension because he threw a sharpened pencil into the drop ceiling tile. He saw a friend of mine do it and thought it was the coolest thing ever."
"A kid on the football team heard about what had happened and protested the suspension directly to the assistant principal. The a** principal stuck firm to his decision and threatened 'and if anyone else gets caught, it will be out of school suspensions….'"
"The following Monday the entire second floor was closed down for the morning. Come to find out the kid and the football team got into the school over the weekend and just blanketed the entire second floor ceiling with sharpened pencils. The video of it was stellar."
These are some legendary moments that every student will remember and can look back on fondly. What we may never know is if they peaked in these moments or went on to do incredible things.
