Age Disadvantage

A gray haired Ivy league genuis professor played a game of Chess with an unknown opponent on the Internet. He played all educated and experienced moves and after long grueling battle lost to a very intelligent and worthy opponent.

Conceding and admiringly, he asked the opponent thru message board on the screen, �How old are you?�

The opponent sent message back, �I am Fourteen, sir. How old are you?�

The professor with blushed embarrassed face writes back, �I am Twelve."
