Nice to know!

Your food has 7 seconds to get from your mouth into your stomach to come.
A human hair can carry about 3 kg.
The average man's penis is three times the length of his thumb.
A woman's heart beats faster than that of a man.
There are about one trillion bacteria on each of our feet.
The skin of an average person weighs twice as much as his brains.
The body uses 300 muscles to balance itself when you are stationary.
Women are now ready to read. But the men.....??????
They are still busy with their thumb to measure.
