AESOP, THE MOST POPULAR storyteller of ancient Greece, told thetale of the fox and his beautiful tail.1 One day, to the fox’s horror, a hunter shoots off his tail. The fox does not know which is worse, the pain or the shame. Then he hatches a plan. Proudly he rejoins his friends and announces that he has got rid of his cumbersome and impractical tail. Soon, there are no tails left in the land of the fox.
