F*ck This Becker Kid
As a fellow 36-year-old, I feel your pain. Shit, I can't even stay awake as late as I used to as a younger man. I cannot begin to imagine attempting to play competitive tennis against opponents 10-15 years younger.
PS - To the biological offspring of Andre Agassi and Stefi Graf, don't even think about picking up a tennis racket. The expectations will crush you. Guaranteed. To quote the old H&O song, "You can rely on the old man's money..." Do something else you enjoy. Trust me.
