Prehistoric eye: Our eye are very sensitive and can notice single light photons. on a bright day, the eye can see the Andromeda star group, the nearest galaxy to earth – without any telescopes. That galaxy is 2 and a half million light years away. but when the those light rays started their journey from Andromeda to our eyes, there were no humans on earth. Which means that when we look to that galaxy, we are actually looking back in time – around 2,500,000 years back.

The world in two testicles: Man’s testicles produce over 10,000,000 sperm cells everyday. this is enough sperm to repopulate the entire earth population within 6 months.

Amazing

Disappearing brain: By the age of 35, a human will lose about 7,000 brain cells everyday. Unfortunately for us – those cells will never re-new.

Cartilage is one of the single tissues in the body that keeps growing while you get older. For example – the nose keeps on growing from the 3rd decade and up until the 7th decade of a life time in about 2 and a half centimeters. and the years – by half centimeter.

The human lungs include over 300,000 tiny blood vessels if we put them next to each other – they will reach to about 2400 km like the distance mentioned above.

The human skeleton is as strong as granite stone. if we make a brick from a human bone – it could support up to 9 tons of weight, just like concrete.

The human’s biggest organ is the skin. its cells are falling nonstop. during a lifetime – a human will shed over 18 kg of skin.

A man can survive in space a few seconds without an oxygen mask. in about 7 seconds without oxygen – he will faint, and in about 4 and a half minute – the brain will die.

A blood drop only needs 30 seconds to complete one cycle of surrounding the human body completely.

Evidence from the past says that a human can survive 40 days without food, 11 days without sleep, 6 days without drinking and 4 minutes without air.

The human eye can notice about 1,000,000 diffrent colors and shades. but only 90% of that information is transfered to the brain. Our nose, on the other hand, can tell the difference between 50,000 odors.

The beard is the fastest growing hairs in the body.

Our thumb in the feet is one of the most important structures in our body, and helps to keep our body stable while standing.

Very thick and very thin: the Aortic artery is the largest blood vessel in the body and in a mature man can get to the thickness of a garden hose. on the other hand, Capillaries are the smallest and thinnest blood vessels. You’ll have to join together 10 Capillaries to get to the thickness of one hair.

Every half cm of skin includes 5 meters of blood vessels, 3 meters of nerve fibers, 1,300 nerve endings, 100 sweat glands and 3,000,000 cells.

Same thing applies to being kept in a box, i think.

You've got anything close/related to bioelectromagnetism?

No sir
