The human body is an extremely intricate and complex system, which despite years of research and medical advancement, continues to baffle researchers and doctors globally. Hence it is plausible that even body parts and functions we deal with on a daily basis have strange or unexpected facts and explanations behind them. Finding out about some of these crazy facts will hopefully help us know ourselves a little better on the inside.

The largest organ in the human body is the skin and in a male adult, if it were to be stretched out, it would cover about 20 sq ft.

Shockingly there are about 32 million bacteria on every square inch of skin on the human body but thankfully most of them are harmless!

One of the most complex parts of the human anatomy is the brain,which operates on the same amount of power as a 10-watt light bulb and nerve impulses sent and received by the brain travel as fast as 170 miles per hour! The brain’s memory power is mighty impressive – according to research the human brain can store five times as much information as the Encyclopedia Britannica. And interestingly the brain is more active at night than during daytime.
