Welcome to the thread "say some complex or mind-blowing fact about the human body, human mind or science in general." begin!

women don't have penises

The bacteria on and inside your body massively outnumber your body's own cells

There's a skeleton inside your body right now and when you die it'll escape. That's why they bury you in a coffin, so it doesn't escape.

The average human has exactly one Fallopian tube

We arent the same inside at all

10-12% of people do not have one of the following muscles: palmaris longus, plantaris, psoas minor

Many people have an extra spleen (acessory spleen)

Many people have a large, fused kidney down in their pelvis instead of two seperate kidneys up in the rib cage (horshoe kidney)

A substantial number of people have extra set of ribs off C7 vertebrate

Around 2% of people have a piece of small intestine attached to the bellybutton. In some people they can shit out of it (meckel diverticulum). Others have something similar but to the bladder so they can piss out their belly button (patent urachus)

Around 5% of people have 2 cusps to aortic valve not 3 (bicuspid valve)

Around 15% of people have complete variation in coronary artery pattern. People are either left or right coronary artery dominant and can lead to different symptoms in heart attack

All branches of arteries besides largest named ones are incredibly variable. For instance 25% of people have 4 main arteries off aortic arch not 3. A lot have aorta wrapping around esophagus

True redpill: the brain is so variable that when looking at 2 seperate brains, the only real obvious landmark they share in common is usually the sylvian fissure and longitudinal fissure. All other gyri etc completely variable

Massive variation in circle of willis, many people dont even have or have extra arteries off it. In some people carotids barely supply
Any blood and vertebral arteries do most supply

Thousands of others i have noticed in medicine. Basically we are all very different on the inside, and i am not even sure we are all the same species

Oh ya, Physics and math facts are allowed too.

If you're driving and are coasting downhill and throw a ball up in the air, it will land back in your hand.

Humans can elect a racist stupid meme president for real.

were literally floating in space!
