How much time do you spend playing tennis in a week? How much time do you spend stretching/recovering from tennis? And how much sleep do you get a night? What time do you fall asleep and what time do you get up? How old are you? http://findarticles.com/p/articles/mi_m0KFY/is_3_23/ai_n13653757 I've been reading about how sleep affects recovery and it got me thinking about my own habits. I play around 15-18 hours a week. One hour of stretching/icing etc. I get 7-8 hours sleep a night. I usually fall asleep around 10:30-11 at night and I'm up at 7. I'm 37. So I'm getting around 50-60 hours of sleep a week and playing 15-18 hours of tennis at age 37.
