tennis requires concentration, but no vigilance
Hi, I am deliberately picking on you tennis buffs, but as a baseball player in a tennis family I always thought that baseball is a more demanding game.
Ask Agassi or the Williams sisters to serve with runners on base is an entirely different matter. The ball and the action is always in front of you in tennis. It does not appear to require much in the way of vigilance, just concentration.
In baseball, you have to constantly adjust with little feedback, because there are is much less action in the game. In tennis, you can show up drunk and your opponent can whip you into shape until you are playing well. In tennis, you win a point, you lose a point. You are on your own in baseball--your intensity is a purely private matter. Little in the way of give and take from your opponent.
I'll be at the French Open this year, so proving me wrong might help me enjoy it more.
