Biology is fascinating...and a bit gross too.



20 things you didn't know about skin such as...

#Globally, dead skin accounts for about a billion tons of dust in the atmosphere. Your skin sheds 50,000 cells every minute.



# One experiment revealed that Meissner corpuscles—touch receptors
that are concentrated in the fingertips and palms, lips and tongue,
nipples, penis and clitoris—respond to a pressure of just 20
milligrams, the weight of a fly.



# The skin releases as much as three gallons of sweat a day in hot
weather. The areas that don't sweat are the nail bed, the margins of
the lips, the tip of the penis, and the eardrums.
