and they are pretty useful
Some animals have them on tails
to drive away insects and flies
some animals have them
body to protect from heat
and cold and changing weather
some have to protect from predators
Birds have them in shape of wings
which help them to fly and protect
from insects and animals
Fish have in form of fins
and stings to swim and protect
And now I wonder why we humans
have on head and other parts of the body
what purpose do they serve?
Just to have some hair raising experiences!
or to make looks and cut or grow at will.
What ever the purpose may be
yet just to imagine body without
hairs is like tree without leaves.
