The human body is an amazing thing.
It is capable of far more than we ever thought possible.
When studying anatomy we really should start doing a deeper dive into all the parts of the body.
Each organ and limb has a story and function that we never really learn about.
Redditor NorthPengyyy wanted to discuss... the penis, so they asked:
"What are some fun facts about the penis?"
Don't Die
"Fun fact - the erection happens when blood enters the penis, the main "structure" of the penis hardens and expands (obviously), but by doing so it presses the Veins and blocks them. Meaning - the blood comes but doesn't go out of the organ, thus keeping it erect for too long. This is why erections over 6 hours are dangerous because the blood blockage is for too long of a time and the penis can die due to lack of oxygen. I hope it was interesting."

Outaries
"The seam on your testicle sack is where your proto vagina sealed up while you were in the womb."
melonsquared
"So testicles are just ovaries that are outaries?"
datazulu
"Literally yes. They all start as gonads in your abdomen. Girls’ gonads stay and turn into ovaries. Boy’s gonads descend and become testes. It’s why, when you take a hit to the balls, it hurts all the way back up in your stomach and can make you nauseated. Boys still have innervated back up to where the gonads first developed."

"It can break like a glow stick if it slips out while a girl is on top and slams back down on it."

De-boned
"Most animals have a 'penis bone' which allows for instant erections, however, humans do not have this bone. The cause is thought to be because without the bone, courtship, arousal, and mating is a longer affair therefore leading to increased intimacy and pair bonding. The penis is literally made for love."

"An elephant's penis is prehensile, like its trunk. It can be used to pick up objects."
Sea-Woodpecker-610
How come only elephants were granted this gift?

Polar Bears GIF by Nature on PBS
Giphy
"Being stressed out, exhausted, and cold makes it smaller. So the smallest penis in the world should belong to a man being chased by a polar bear in the Arctic."

Wait, what?
"I remember watching a weird YouTube documentary about a spider (in Australia of course) whose bite gives you a forever erection."
JMthought
It Just happens
"Just because it's erect DOES NOT mean the person is horny/aroused."
Spartan0536
"I recently learned that clenching other muscles is a good way to get rid of an erection. The bigger the muscle, the better, so clenching your butt is a good way to go. Apparently, it’s because it causes more blood to go to the clenched muscle. More blood to the muscle = less blood to the penis."
phatcat9000
"I'm quite anxious all the time. When I'm just chilling with nothing else to do, I reach a point of relaxation and I get erections, I'm not aroused or anything, I'm just chilling and it seems that my body approves of my time off I guess."
chifrijoconbirra
Be Smart
"There is a ligament at the base of the penis that causes the penis to rise when it becomes erect. This is what causes a bulge etc."
"Some people have stupidly made the decision to have this ligament cut. This is because it adds a few inches of length to the erect penis. However, it will just hang down. Do. Not. Do. This. It is a stupid thing to do."

"A single sperm contains 37.5 MB of DNA information. One ejaculation represents roughly a data transfer of 15,875 GB equivalent to the combined capacity of 62 MacBook Pro laptops."

Well, the penis is far more interesting than we thought.
Isn't it?
Do you have any interesting tidbits to add? Let us know in the comments.
Redditor r3tr0gam3r83 wanted to hear about which realizations in life have left people SHOOK, so they asked:
"What is something that blew your mind once you realized it?"
Avocados are not vegetables.
They're fruits, berries to be exact.
Like what?!?!

Star Trekking
"That you could legitimately travel at warp speed through the center of galaxies and never run any real risk of hitting a star. That’s how spread out space really is."
justanotherguyhere16
"Also, galaxies, stars, and even the Universe is constantly moving. I think time travel has been invented, but they can’t figure out the 'space' part of it.
"Yes, they can travel back in time, but relatively speaking, they can’t figure out how to navigate to the part of the planet they want to reach. So when they travel back in time, it’s relative to where they currently are, and end up not moving through space, thus ending up in the middle of an empty vacuum."

Jaws is Old
"That sharks predated the rings of Saturn."
BeardedDominant
"Sharks also developed the immune system that ended up in both dinosaurs/birds and mammals."
csiz
"We don’t know that. We can’t say for certain that the rings are only 100 million years old. It’s still debated."
The_Kek_5000
"I'm pretty sure that sharks are older than trees."

From the Trees
"One day I sat on a tram, passing a river. There was a duck in a tree. I realized I'd never seen ducks in trees. No one else seemed to notice, but I was puzzled. Now whenever I come across something that seems intuitive but I have never considered I call it a duck in a tree."
Ol_Pasta
"This realization happened to me this past year. We apparently have a family of wood ducks in one of the big trees in our yard. Our neighbor said she has seen a duck walking around on a branch. I made it 37 years without knowing some ducks can roost in trees. My wife caught a video of the mama leading like eight ducks into the field next to our house. We aren't even near water."

Oh the Power
"Nuclear power plants are just steam power plants that use nuclear reactions to heat the water. There's no fancy magic extracting energy directly from nuclear material. They just boil water and spin a turbine."
RenaKunisaki
"Most electrical generation is spinning a turbine. Photovoltaic solar power is pretty much the only exception, and it's not the only form of solar power. There's solar thermal power, which uses mirrors or lenses to concentrate the heat of the sun to make steam and turn a turbine."

The Empire
"The Roman Empire fully fell less than 50 years before the discovery of the new world."
South-by-north
"The Romans also had copper wire, magnets, and battery acid. They could have invented electricity hundreds of years before it was actually discovered. But they didn't. The wire was used for jewelry, the magnets as lodestones, and the battery acid was used to clean the rust off of swords."
Kahzgul
"RIP Byzantine Empire. 1453 never forget."

The Witness
"Owl‘s silent flight. I mean I always knew that but a while ago was the first time I actually witnessed it. Owl came flying towards me and landed only a few feet away and you couldn‘t hear anything. Crazy."
Zealousideal-You-324
"I saw a barn owl swoop down and catch a mouse while hiking at night, and the whole thing happened in complete silence. It gave me a deep sense of unease because it was literally like someone hit the mute button on life."

Kermit The Frog Meme GIF by IdentityGiphy"Poison dart frogs aren't poisonous in captivity."
"I own 5 of them and anytime I tell someone I own some I always get 'Do you ever lick them' or 'Can you go kill someone with them.' But yeah they get their poison from what they eat, and all I give them is fruit flies."
JMfury
Poison frogs?
That sounds like something Rose would have a story about on 'The Golden Girls.'
But thanks to an unnamed Redditor, some of those were revealed when they asked strangers online:
"What are some really creepy facts you know ?"
Scientific facts like these can be downright terrifying.
The Sound Of Prey
"Dogs like squeezing toys because it sound like a dying animal."
– Nain6969
"My dog loves squeeze toys except the chirping bird toy we got for our cats. If he hears it he picks it up very gently and brings it to us and then whines and is distressed by it."
– CopperTucker
Ominous Mass
"There is a black hole called Phoenix a, and it is estimated to be 100 billion times the mass of our Sun, comparable to the mass of an entire galaxy. Its event horizon is 590 billion kilometers wide, or more than 100 times the distance from the Sun to Pluto, or about 1/16 of a lightyear wide."
"To get a visualization of how big that is on a human scale, lets shrink our solar system by 1 trillion times."
"The Sun would be 1 millimeter wide, and Pluto would be a little more than 5 meters away, and that black hole would be 590 meters wide. For reference, Alpha Centauri would be about 40 kilometers away at that scale."
– Youpunyhumans
Easy Passage
"Take away the stomach acid and an octopus could go into your mouth and crawl out your a**hole."
– Resident-Clue1290
Creepy Crawlies
"Spiders, one of the most evolutionary advanced species on the planet. We keept killing them, they began to get better at hiding. They can also convince us we have killed them when we haven't. Rain doesn't destroy their webs, not even a pressured hose does anymore."
"Also forgot to mention, they can do nothing, sleep all day and wake up to find food in their webs. They do not need to hunt or attack like almost every animal."
– Unlucky_Ducky23
Some of the sinister forces around us are the work of humans.
Murderers In Our Midst
"As many as 50 serial killers are active in the US and on the loose."
– Individual_Bit_8528
"Wayyy more than 50 if you include organized crime affiliated killers. Probably a lot more than 50 lone weirdos killing strangers too, but definitely hundreds or more if you include the former demographic."
– fluffedpillows
Corruption
"A guy disappeared in my country. Everyone knew he died. Everyone knew who did it. But the guys were policemen. So the investigation was so ruined it became ridiculous."
"There are people on this planet who can interven in the investigations made against them, decide to block them and if you do something about it, no one will investigate when you will mysteriously vanish."
"Can't fathom to be so powerful but yet use this power to be so heartless."
– Least-Designer7976
A Patient's Risk
"In 45 states, doctors and medical students are legally allowed to practice pelvic exams on patients who are under anesthesia without being granted explicit consent to do so."
– TrailerParkPrepper
Feasting On Flesh
"The first known human cannibal was a Neanderthal whose victims' 100,000-year-old bones were discovered in Moula-Guercy, a cave in France."
"There have been sites where the act has occurred involving the cannibalism of children leading some to speculate the act was not just done for food, but that it was done as a warning to rivals."
"Some anthropologists suggest that cannibalism was common in human societies as early as the Paleolithic."
"To this day only a few countries have laws which explicitly criminalize the practice of cannibalism, and the act can still be found in isolated regions of five different Countries."
– JustSomeApparition
Death itself is a mystery.
Ill-Fated Flight
"The crew aboard the Space Shuttle Columbia was still alive for several minutes during the fatal and futile reentry attempt."
"The first signs of trouble were observed at 8:53:46. More and more started to go wrong but Mission Control was able to maintain communication through 8:59:32. Sometime after that, the shuttle entered a flat spin while traveling approximately Mach 15, which is enough to cause disorientation and very painful injury, but most likely not unconsciousness or death. Review of recovered data recording shows that Commander Husband and Pilot McCool were still attempting to restore systems and recover control past 9:00:05. The first lethal event was depressurization, which occurred between 9:00:35 and 9:00:59."
"All that means that the crew was very much alive and very much fighting to maintain/regain control for more than 7 minutes despite knowing that realistically their chances of success were pretty much zero."
– HoopOnPoop
After The Chopping
"Supposedly you're still aware for a few seconds after being decapitated."
– Broski225
"There was that one scientist or whatever who got beheaded in France. He said he would attempt to blink as many times as possible after his head was lopped off, for science, and his head did. I'm paraphrasing since I don't remember anything about the story but whatever. lol"
– Adkit
Now you know.
Some of the scariest things in life are our real living nightmares, and once you know about them, you can't unlearn them.
Reading through some of these examples, it's very clear that our world is a mysterious and creepy place to live in.
Sleep tight, and don't let the bedbugs bite.
Redditor rui_xox33 wanted to discuss some of the darker aspects about this mortal coil, so they asked:
"What are some creepy facts about human nature?"
Get Naked
csi miami GIFGiphy"On a recent date with a CSI agent I learned that a lot of people die naked on or near the toilet. Apparently people get very hot and try to strip down when close to death."
KingPnutticua
Like a Starfish
"We possess the genes for regeneration similar to starfish and salamanders. They are on the same chromosome as the genes for scar tissue formation. However they are not turned on whereas the scar tissue genes are."
"So technically, we could pull a Piccolo and regenerate limbs like a starfish."
"But we don't because it's waaay too metabolically demanding on energy. If we could do it, you'd likely shave years off of your life in exchange. Instead we make scar tissue to reinforce the injured area."
StopFool
Moving Parts
"After a back surgery, your organs might have been moved to perform certain parts of the surgery. The doctors don't move your organs back to their original place. This funny feeling you get after the surgery is your organs moving themselves back to their original place. Yes, they are capable of that."
VetreeleekYT
Separate Systems
"The eyes have a separate immune system than the rest of the body. If your body's immune system realizes your eyes exist, it'll attack the eyes and reject them from the body as it would a virus."
berripluscream
"I also have a fun (?) fact about the eyes: The retina isn’t really fixed in the eyes."
"The part where the nerves leave them is quite inflexible but towards the outside/lens the retina is staying because of osmotic pressure. I know because I had a blood vessel that somehow leaked and a couple of months later the retina in that eye detached in a big way. It’s not so funny when several doctors say something like, 'that doesn’t look good' when examining your eye."

Object Around You...
drumming sub pop GIF by Sub Pop RecordsGiphy"If you happen to have brain injury, there is a condition that makes you unable to recognize objects around you. Like, you will see a fork, the colors and the shape of it, but you can’t know how to use it, if it’s edible or not, etc. Pretty scary thing to imagine."

'Clearly Remember'
"Learned memories, i.e. people 100% sure they remember things which actually never happened but were told many times by media/memes/others. I observed this for certain episode which happened less than 10 years ago and which everyone whom I asked witnessed themselves personally, but they all 'clearly remember' it in a way it was presented in memes and jokes and not how they actually saw it happen."
p17s82
Head Issues
"Risks during birth are abnormally high compared to other species. Because of our upright gait (mother's narrow pelvis) and big heads, fetuses cannot 'fully' gestate until being born. Humans have to be born prematurely while the head is still tiny and squishy. Otherwise, childbirth would not be survivable at all."
deepestfish
"Gives Out"
"Most people that die due to hypothermia get naked before dying."
"This is because, blood stops flowing to your extremities, so you don't lose body heat. Just before death, the brain kinda 'gives out' and allows blood flow to return to normal. This sends warm blood to your cold limbs, making you feel very hot and sweaty, so you strip."
