Fear...

when we are face to face with a tiny spider, we always like to retell the tale to a friend...but! instead of saying there was a tiny spider in the bath, it changes to:
"OH, WOW! YOU WOULD NOT BELIEVE THE SPIDER IN MY BATH TUB LAST NIGHT! IT WAS HUGE! IT WAS OF THE DEEPEST BLACK THAT REMINDED ME OF THE NIGHT...OF DEATH...AND ITS LEGS WERE SO HAIRY, I INSTANTLY HAD THE URGE TO GRAB THE RAZOR!...BUT ITS EYES! OH, IT HAD AT LEAST A DOZEN, AND ALL OF THEM RED, THAT STALK YOU, FOLLOWING YOUR EVERY MOVEMENT! IT WAS JUST SITTING THERE, WATCHING...WAITING...WAITING FOR THE RIGHT MOMENT TO POUNCE ON ME AND SUCK OUT MY INSIDES WITH A STRAW THAT IS WEDGED BETWEEN HIS ENORMOUS FANGS!"
I admit, a slight over exaggeration, but why do we exaggerate? (Quick Note: it is proven that males exaggerate more than females!) Fear. Fear compels us to magnify everything, but why do we let us be ruled by fear? why does Fear rule our everyday life, instead of us?
is it not the reason we cant sleep at night? but what is it we truly fear? What is the one thing that mankind detests?
