The human body is everything that makes up, well, us. However, there are plenty of fascinating things we don't know about it, or rather, ourselves.
Once you look closer, dive under the surface of the skin, explore the inner workings of the biological systems that ensure our everyday life, you just can't help but admire the marvel that you really are.
To learn more about our bits and pieces, Redditor u/Zenssei made a post on r/AskReddit, asking other platform users to share some facts about the human body that not many people know about. Their call to action was immediately answered.
u/Zenssei said the idea for this post came to them pretty naturally. "I was just watching TV, thinking of [something] I could post on r/AskReddit," they told Bored Panda.
"I have learned quite a bit from the comments such as there is a right and a wrong way to swallow, or that about 20% of people have a bone ridge on the roof of the mouth... It was fun reading through the replies."
As of this article, the post already has received over 56K upvotes and 23K comments, and has become one of the coolest online trivia archives out there!

Your brain likes stimulation, if it doesn't get any it will make some up, some people are more sucepticle to it then others, the colors you see before you fall asleep are a common mild occurrence, there are several classes of these hallucinations, closed-eye visuals, which are caused by leaving your eyes closed for a long time, hypnagogia, which is caused by the onset of sleep, prisoners cinema, which is caused by looking into a dark place for a long time, ganzfeld effect, which is caused by blocking out all external stimuli, and Charles bonnet syndrome, caused by sight loss.
Most are these are simple phosphenes but some can be whole imagined scenes, or more abstract fractal-like imagery

When you have a bowel movement, your heart rhythm shifts temporarily due to a vagus response. The reason Elvis died on the toilet was because his heart was beating 200+ bpm and the quick rhythm change caused a myocardial infarction. People with low heart rates have been known to pass out on the toilet because their bodies can't handle the shift.
It's also why EMTs will absolutely not let you use the bathroom before getting on the ambulance. Especially if the bathroom is a standard 5'x8'.

Synovial joint fluid is the most frictionless stuff on the planet (unless they've synthetic'ed something up that recently.)
