One day the man throws a no-hitter and is the hero of fans and press. A few days later (apologies to international readers) the poor guy can't get the ball over the plate. One day the Nobel Prize winner is the smartest person on the planet; a few days later the savant can't remember their own name. This is one act in the play known as the human condition. Some times as I leave the house on the bike the legs have tremendous snap and power and I feel like a GC contender. Another time as I leave the house on the bike I may begin to think how nice it would be to spend the afternoon at the bookstore.
