35 Cool Human Body Things, As Shared By The People In This Online Thread
The human body is truly amazing. Did you know that when we're born, we have around 300 bones, yet by the time we grow up, some of them fuse together and we're left with only about 206? What's more, human bones are incredibly strong. You may have heard that they're stronger than steel, but did you know a block of bone the size of a matchbox can support up to 18,000 pounds of weight?
Perhaps you knew these facts; perhaps you didn't. That doesn't change the fact that our bodies can do stuff that is pretty darn impressive. Recently, people named a few more of these facts in an online thread after one netizen asked, "What is the coolest thing that the human body does?"
So, scroll down and see what other remarkable things your body is capable of – perhaps some of them will be new to you?

Dreaming. The body is like, "Not only am I going to repair your cells while you sleep, I'll also keep you entertained with this trippy, absurdist, avant-garde art house movie I created just for you.".
I have amazingly vivid, complex dreams. They're sometimes so vivid that it takes me a while after waking up to realize that they were, in fact, just dreams.
I have dreamt before I was dreaming in my dream. Also I have had dreams that seem so real I didn't think I was dreaming until I actually woke up.
Load More Replies...I've had dreams featuring previous dreams. I once dreamt I was flying over China, and some months later I dreamt I was sleeping and had been dreaming about flying over China.
I have so many dreams about homes! They are always huge, with rooms I keep discovering. Many have similar features from previously dreamed homes. There are often guests or parties I was not aware I was supposed to be hosting. The dreams are so complex I don't know what to make of them. Most of my dreams are very explainable because of recent info or emotions. Or typical, like showing up to class unprepared. But these home dreams are fascinating to me!
I also have dreams where I keep discovering new rooms and features in my (dream) house. I love those!
Load More Replies...I have episodic dreams. I was traveling across country looking for a home, then I started dreaming about picking out furniture for it. This went on for weeks.
My dreams are just weird. 3 things that ALWAYS happen: my phone doesn't work, lights are burned out, my car gets stolen or I lose it somehow. 🤷♀️
I have epilepsy and the way minor fits manifest themselves is I get brief "flashbacks" to dreams I've had. If the fits get bigger then eventually it's like I go backwards into the dream and at that point I "pass out". When I was being diagnosed I had to talk to various doctors and several of them called other doctors and even students into the room (with my permission) and asked me to repeat the description of my symptoms - presumably because it was a bit odd, but who knows!
Having babies.
Like, literally, this is impressive a single cell becomes a whole human in 9 months, it has a brain, walks, learns.
Nature is a clockwork.
More correctly, two cells - egg and spérm cell meet and create a new living being that bcomes a whole human over that approximate 9 month span.
Most mammals anyway; echidna & platypus both lay eggs. There are some fish & reptile species that have live birth as well. Interestingly, some reptiles & sharks (such as the western garter snake, cottonmouth, and great white shark) are what's called "ovoviviparous" which means the young develop in and hatch from eggs *while still inside the mother's body,* after which she gives birth to live babies. How cool is that??

Secretes copious amounts of mucus in response to tree and grass j**z. It's not really cool, and I hate it. But it never ceases to amaze me how fast it can replenish it. Blow your nose, and 10seconds later it's completely full again, rinse and repeat for hours. WHERE IS THIS S**T COMING FROM!!!!
Who was it that commented that jízz wasn't a censored word a while back and somewhere else? It is now! The censor bot learns fast, it would seem!
Soon everything will be censored until we open the site and, like 2001:A space Odyssey, 'Oh my god: it's full of stars!'
Load More Replies...I remember as a kid having a major cold thinking the same thing. Massive amounts of snot that never stopped. Whole box of tissue used. It was kind of scary!
I asked my GP why I didn't lose weight when I had hayfever because of the astonishing amount of snot produced and she likes at me like I was simple 😂
To add insult to injury, antihistamine medication prevents you from losing weight. 😒
Load More Replies...Mucus is the bane of my existence. It literally takes two hours to flush it out once I'm awake and upright. It's not gross, but annoying. I call it nose juice, and it runs like a faucet. No medicine on the planet has worked to slow it down. I have lots of breathing allergies btw.
Here a lot of people with breathing allergies and respiratory problems go to live close to the sea. The sea air is better for them.
Load More Replies...Unfortunately, just because you don't have allergies now doesn't mean you won't develop them later in life.
And that orifice was located with the discharge area aimed directly over your mouth. Poor planning, maybe? :)
Creating life.
**Breast milk** is also mind blowing. When a baby latches on, the mom's body "reads" the baby's needs from the baby's saliva (through pheromones and stuff) and produces the milk the baby needs!
Breast milk does not have the same composition throughout all the months a baby eats it, because the baby's needs change. Breast milk from two moms who have babies of the same age will also not have the same composition.
If a baby catches a cold or gets sick, the mom's body will produce milk that helps the baby heal.
Breast milk is the most personalized food that exists. 😁.
I tell my mum that when I get a cold. I'm 68. She says no. Grrr.
I laughed so hard. "I'm 68. She says no. Grrr." Bless you!

I've always found the ability to stand upright pretty wild. We're relatively tall and top-heavy and our feet aren't very big. The amount of brain processing required to keep that shape upright, let alone do something like dancing or ice skating, just seems insane to me. Your brain is doing countless little micro-adjustments constantly whenever you're standing, and yet it feels completely effortless.
Yeah, and now I am finding out just how awful it can be to lose that balance
Yeah, it sucks big time when your eyes and inner ear don't agree with each other. Thank ghu I am not susceptible to motion sickness..
Load More Replies...The best thing you can do as you age is to fortify this ability. Falling kills. Work your core and keep moving.
Omg this!!! Yeah, when I was learning to literally walk again? I did get frustrated by my stoopidy feet not co-operating! The physiotherapy staff were wonderful and completely understood 💜🙂💜...... It's so complex and beautifully weird as to how our brains are all wired... Our spine signals, the messages from our brain to our feet etc 🙂
I always stand straight and tall, but I'm constantly called unbalanced. Go figure.
Stand on one foot with eyes closed. Switch feet and do it again. See how long you can do this for - a minute is very good.
I do this while waiting for the kettle to boil, I’ve got better with practice but can’t often manage a minute on both sides!
Load More Replies...All those countless little micro-adjustments left me with a very bad back. Ugh
I have flat feet so my brain must really work overtime keeping me upright.
The fact that your brain can literally make up entire movies while you’re asleep, complete with plot twists, random cameos, and locations you’ve never even been to and you just… accept it until you wake up.
Or when we dream of someone we havent seen in 8years...then you see them the next day. I want that science!
In blunt terms? I was told by one of my therapists that dreaming is basically getting rid of the "junk". You may not remember them but nightmares are healthy. Scary yes but healthy........ What I do is, if I have a horrific nightmare? I write it down in a notebook, think - "Am I under a lot of stress atm?"... "Okay yeah. So write it out and look up what you need to do today. Who do you need to phone? What positive things can you do today? Look up phone numbers etc" 🙂
That they say the brain literally remembers bits of every face, every place and every sound you've ever seen or heard, be it in real life, on TV, movies, radio, whatever, and a lot of those bits are combined to make up "dreams." With my dreams, I'm always in an abandoned town, a building, whatever and those buildings are always near a creek, small river or canal. Can't find my car, either. Odd.
I had an extremely detailed dream about going into a hotel in Barcelona and being greeted by Carlos, who took us to our suite. 15 years later we did a European tour. In Barcelona we arrived at the hotel. My husband knew about my dream. Walked in, and Carlos took us to our suite and it was exactly the suite in my dream. We were both gobsmacked.
I have dreamy about things I have had no contact with. Where they come from I don't know.
It allows a fart to evacuate AROUND a poop thats nearing the exit hole. A gas can pass around and uninterrupt a solid in your a*s without mess. Wild stuff
Edit/ judging from the responses, many of you may have undiagnosed ibs or crohns just sayin.. Or ate some spicy burritos last night.
Much more interesting for me is the fact that the sensations in this area are that, ah, sensitive that we usually can tell if it is just gas or solid.
"Usually" being the operative word here, LOL.

I held my urine way too long one time, riding a train downtown to a concert, assumed there would be facilities. There were not. I squeezed so tight..so much pain, it finally just started on it's own, my sphincter wore out I guess. So. I saw Iron and Wine with Calexico in pee pants. That was years ago and I still feel like I have to go constantly when there's nothing to expel. Edit: If you get off Metrolink at Grand in St. Louis there is no guarantee you will be getting back on. Luckily an officer noticed us and askes what 3 white boys were doing getting off at Grand. I said I had to pee, he laughed and waited for the train with us.
If you like singer songwriter type music check out Iron & Wine. a few good songs to start with are: Hickory, Trapeze Swinger, Sodom South Georgia. It's a husband and wife with a very unique style. You're welcome.

I mean the heart is pretty darn cool, it's an engine that runs constantly for up to over 100 years.
Coolest muscle in the whole body. Functions independently of the brain, which is super neat.
"...for up to over 100 years." So which is it, up to 100 years, or over 100 years?
Your eyes don’t give you a perfect picture of reality, they send bits of info, and your brain fakes the rest, it edits out your blind spots, flips the upside-down image, fills in blurry peripheral vision with guesses, and even predicts the future by a split second so you feel "in sync", youre basically walking around inside a braingenerated VR.
WindySwede: I've read that we've got vision which is incredibly well optimised for our needs. Apparently, our highest resolution vision beats most other animals except birds of prey. No UV or IR sensitivity, poor in the dark compared to many - all that is true. But we're damned good at fine details both close up and far away - and many other mammals only have two colour vision, not our three colour setup.

Digest chocolate. We're one of *very* few mammals who can safely eat the stuff.
I do eat much more of it for all the sad mammals who can not. I am sort of balancing it. But are they grateful? No! Not a single mammal ever thanked me for the sacrifices i bring for them 😞
Ungrateful, aren't they? All the tons and tons of tasty, delicious sacrifices we make for them, but they just don't care. Makes me mad! How many more sacrifices do we have to make until they understand!?

Heal, 100%. I broke my Ulna (left arm bone) in April. 2 nights in hospital (in Thailand, alone, with no Thai). Surgery, 13 stitches, 2 screws. I am 63F, 52kgs, 163cms. Thought it was going to be a long road to get better. In a month with strict rehab (at home, following instructions), I was 50% back to full movement, gym workouts and pool swims (50m x 18 laps - just couldn’t pull myself out on the pool ladder, so had to use the pool with the steps in and out). 3.5 months later, I would never have known I broke my arm. Our bodies are amazing.
You must be young. The body heals so much more slowly when you're older. Good for you for following instructions. It makes a world of difference.
Your stomach gets a brand new lining every few days so it doesn’t digest itself… which is both amazing and slightly terrifying.
The Placebo Effect.
It's not just "thinking you feel better." Your brain, through pure belief, can create real, measurable, physiological changes in your body.
If you believe a sugar pill is a powerful painkiller, your brain can actually release its own natural opioids (endorphins) to reduce your pain. Your brain can reduce inflammation, lower your heart rate, and ease depression, all because it was tricked into thinking it was getting help.
It's literal mind-over-matter. The fact that our consciousness can directly influence our own biology on that level is, to me, the most powerful and coolest thing a human body can do.
It also has an evil twin: the Nocebo Effect, where believing something will harm you can actually cause negative symptoms.
I've actually overcome insomnia by pretending that I took a sleeping pill.
I wish that worked for me. Even at 8 years old my brain knew it was just a vitamin C tablet, though I wasn't told that until after.
Load More Replies...I have a weird ability to "think" away pain - especially headaches. If I concentrate on the location of the pain I can "push" it away. If my concentration lapses the pain returns. Don't know how to explain why it works.
I used to do it too and then I got migraine...
Load More Replies...I used to believe the brain was the strongest organ, because I could make myself to sick to go to school on a whim. Then I got older and learned the true ruler of my body is my colon. And it doesn't like me.
The brain is kind of a jerk. It has all the good chemicals, but you have to trick it or hack it to get any.
It can also be tricked into thinking it is drunk. So you would be drunk driving, but have a negative alcohol test...
One of the most amazing things about the human body is the brain’s neuroplasticity. Even as adults, our brains are capable of forming new neural connections, adapting to change, and learning new things. This means that we are constantly changing and growing, regardless of our age or circumstances. This flexibility of the nervous system is a unique trait that sets us apart from many other species.
I feel like my new mental skills at an older age are compensating for memory loss. I have to substitute words I don't remember, offer alternative descriptions, use mnemonic devices to retrieve words I know I know ... it's a different kind of mental gymnastics that I hope are keeping my mind in some sort of shape!
I read recently that just walking around nature a little bit everyday can improve your learning abilities.
Load More Replies...Learning new things keeps the brain active. Keeping the brain active wards off dementia.
Brain. the comprehension and problem solving skills mixed with artistic ability and emotions is absolutely astounding.
Immune system. Basically our automatic defense against foreign bodies!
Until it starts attacking your own bodies healthy cells because it has gone wacko, causing an autoimmune disease that becomes a lifelong incurable condition.
✋️ Exactly. Immune system: "There is something bad in there. We mut destroy it." Body: "Great! Thanks! All better!" Immune system: "There it is again! Ahhh!" Body: "No, really, all good here!" Immune system: "Kowabunga!" Body: "Nooooo! I need that!"

I havent seen a single comment about the uniquely h**h endurance humans have compared to other animals, we survived as endurance hunters chasing animals, not with our speed, but by walking them to death by following them until they were too tired to continue walking. Take any average healthy man, and put him up against a elephant to see how far they can get before their body physically cant handle it, and the person will go way farther.
I am the person with whom you want to flee- because the predator will catch me first. so if anyone wants to hike safely: I am your girl and will keep you safe
Load More Replies...Not in a hunter way but when I was in the physiotherapy hospital? Myself and others... I shouldn't speak for them but? We learned exactly how far we could and can "push ourselves". I saw others and knew myself would be okay, kinda, in the end. You learn a LOT when something drastic happens, how much you can endure and take... It's surprisingly a lot.
Once upon a time I was actually genuinely physically fit. The issue with any other animal that can go quickly in short bursts is that yeah, if it doesn't catch me I'll be ahead in a mile or two - but I've still got to escape its claws...
I thought this was because we can sweat, or at least sweat better, than other animals?
I like reading things about humans being so awesome compared to aliens in the universe in the various works of fiction online. We're considered such dangerous beings for living on a "death world" and whatnot.
This one is kinda stupid. Many animals spend their entire lives walking. Ruminants walk their whole lives in search of food, as do a great many animals. Humans on the other hand are good for bursts, unless they are trained for endurance. Think about it, when we take on a task, we can't just work at it indefinitely without a break. The OP is cherry picking.
The way the body filters all the good and bad c**p that we eat and drink, and still function.
Adrenaline. Pretty much transform you into a super human for a min.
Unless, of course, the body is releasing adrenaline when you don't need it and you just get to be shaky and sick
Yup I had a massive panic attack right before my emergency c-section Got up off the surgery table and walked out of the OR *With an epidural*
Sweat. It's fairly unique to humans, at least to the degree we're able to regulate our temperature. This, along with bipedalism, is what makes us the greatest endurance hunters in the animal kingdom. All this without acknowledging our ability to share imagined realities (i.e., religion, laws, rights, companies), cooperate adaptably in large social groups, or to use logical reasoning and executive function.
Memory formation. Neurons fire in the same pattern over and over again when a memory is formed until it becomes easier to fire in that same way, so when you access that memory they activate the same pattern. Memory formation is really cool.
When someone uses their ex's name instead of the new partner's name, it is because the brain is associating the new partner with the old feelings. But the pattern of those feelings is stored in the brain with the ex's name still, so it gets used instead of the new one.
Also when there's family around it's so easy to call someone by the wrong name!
Load More Replies...Everything in your life, except for this exact present moment, is a memory.
I personally found our immune system quite cool on how it detects pathogens, destroys it, and then creates memory cells of the pathogens.
Unless it goes crazy and starts attacking itself. I have autoimmune and hate my immune system.
Just about to say this. My immune system actually sucks.

How playing a sport regularly gives you incredible muscle memory.
I took karate classes along with my kids. They dropped out - I continued. I adopt the stances they taught all the time. Any threat or any physical activity - foot back, knees bent, hands up ... don't mess with me!
Something you don't think about, but would be in trouble if it didn't happen: sweating to cool off.
Recently was playing a casual sport when the temperature wasn't astronomically high, but the humidity was. Was astounded by the amount of sweat I produced in an attempt to cool me off. I could wring out my clothes and ponytail and produce drips. Don't know if it was a normal amount and I only noticed it because it couldn't evaporate, or it was excessive because my body was like EMERGENCY COOL DOWN: ENGAGE!
This is how people end up with heatstroke. It can quickly be one an emergency. If the body cannot regulate temperature by sweat evaporation body temp jumps up. It does not have to be overly hot outside for this to occur.

My wife generated 2 fully functional, completely operational, human beings out of like....a teaspoon of goo and a bunch of food. They popped out of her hoohaa, and when it was over, she claimed that it was, and I quote, "not really painful, just sort of uncomfortable" end of quote. I'm going with that.
The most brave, bold, and wonderful I’ve ever felt was after I birthed my son. I honestly felt I could take on the world. What could be harder than birthing a human being!?!? (Well, other than raising one.)
Uncomfortable? My son was a month premature, was 5lbs. 9 oz., and 2 days of labor later was begging for an OREO to hold in front of my hoohaa to coax that little bugger out!
Ummmm my labor was INCREDIBLY painful. Like I was being ripped apart from the inside. Fortunately got an epidural (though it was almost too late), so I didn't feel the birth part too much, but still! It suuuucked.
Glowing. Yes, you glow a faint light all the time. You come from star dust, literally. And you are spinning around the Milky Way center at 100 miles per second, spinning around our sun at 67,000 mph, spinning around earths core at 1000 mph.
That’s not just cool, that’s flat out amazing!
I glow a faint light all the time? That's what people must mean when they describe me as a dim bulb.

All animal brains are amazing, but the human brain with its self-awareness and ability to communicate is, well, mind-boggling.
Read yesterday, forgotten where, that ants are/can be self aware. Which is cool.
Load More Replies...Skin does a lot of cool stuff. Sweating is actually goated, and rare for animals. It gave us an edge as a predator, being able to chase prey for long distances without overheating. Also the wrinkles that form on your fingers when you’re in water for too long are to increase friction, so you can handle stuff in wet conditions without it slipping as much.
Horses sweat through their skin. Dogs sweat through their paws. Lots of animals sweat, it isn't rare. The wrinkling of skin in water is primarily caused by vasoconstriction, which is the narrowing of blood vessels in the skin. This physiological response is controlled by the autonomic nervous system and is triggered by the body's detection of moisture.

Breastfeeding.
Your milk changes as baby grows to give them the additional nutrients they need, which is why bulk freezing is actually silly unless you have a plan when to use it, or if you are giving it away.
It will also adjust to provide antibodies if baby is sick.

That a single cell can double, double again, and again, and at that forth doubling, the cells start to differentiate eventually forming different organs, eyes, the brain, skin, teeth, bones, ligaments, all the different aspects of a full and complete body - at one time a single cell.
What about skin? It's an organ, too, and most certainly regenerates. We'd be quite the sight by age 9 if it didn't.
