Pythagoras used to say that life resembles the Olympic Games: a few people strain their muscles to carry off a prize; others bring trinkets to sell to the crowd for gain; and some there are, and not the worst, who seek no other profit than to look at the show and see how and why everything is done; spectators of the life of other people in order to judge and regulate their own.
Michel de MontaigneWhen I play with my cat, who knows whether I do not make her more sport than she makes me?
