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. Not only animals but even humans shed skin – a human being sheds roughly 18 kg (40 lb) of skin in a lifetime. 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.
The stomach contains digestive acids that are strong enough to dissolve zinc! Hence we get a new stomach lining every three to four days, as otherwise the strong digestive acids would also digest our stomach!
The saliva produced by an average person in a lifetime can possibly fill up two swimming pools. Moreover our saliva must be able to dissolve a thing if we are to get the taste of it.
Every human being has a unique smell with the exception of identical twins.
A human body generates so much heat that, in a mere 30 minutes, it can produce enough heat to boil a half gallon of water!
Our nose and ears continue to grow throughout our lives while our eyes remain the same size as they were at birth.
It is estimated that the human body has about 60,000 miles of blood vessels.
The human lungs contain in excess of 300,000,000 capillaries, which if stretched out tip to tip, would reach more than 1,500 miles!
Sneezes are known to rocket out of our bodies at over 100 mph while a cough is thought to travel at about 60 mph.
Interestingly, it is said that hearing becomes less sharp after a person has eaten a lot.
Human beings can identify a huge variety of scents and it is said that the nose can remember as many as 50,000 different scents.
According to researchers humans are about 1 cm taller in the morning than in the evening. This is due to the compression of the cartilage between our bones as a result of standing, sitting and various other day to day activities.
And finally, on a lighter note – it is not possible to tickle one’s own self, even the most ticklish people around cannot tickle themselves.
