35 Cool Human Body Things, As Shared By The People In This Online Thread

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.".

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.

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!!!!

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'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.

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.

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.

I mean the heart is pretty darn cool, it's an engine that runs constantly for up to 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.

Digest chocolate. We're one of *very* few mammals who can safely eat the stuff.

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.

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.

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.

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!

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.

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.

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.
