I don't know how many calories an average chess player burns per game, but it often exceeds that of a player in ball games. It is not only the chess as such: You need to be fit and undergo complicated preparation.
Common sense is the guy who tells you that you ought to have had your brakes relined last week before you smashed a front end this week. Common sense is the Monday morning quarterback who could have won the ball game if he had been on the team. But he never is. He's high up in the stands with a flask on his hip. Common sense is the little man in a grey suit who never makes a mistake in addition. But it's always someone else's money he's adding up.
Stevie Wonder used to come the ball games and they would have a guy sitting with him. And the guy would be holding on to his arm, telling him what's going on, and he would say, "Hey, the big chocolate guy just put down a thunder dunk. The chocolate guy with another monster dunk." And Stevie Wonder actually gave me the nickname Chocolate Thunder.
I cannot consider fighting in competitive Manly Fun any more than I can consider pitting my running, swimming or climbing body against other bodies. Nothing, then, or now, arouses me or will ever arouse me from a perfect disinterest in ball games.
