I've been playing tennis for a few months so far. And recently I noticed an annoying fact: the moment your racquet hit the ball it generates a lot of hair. and since you are having such intense sport, you are breathing heavily and sometimes using your mouth to breathe. So I guess a lot of those hair ends up in my lung. I'm wondering how you folks who have been playing for years doing. Do you feel breathing the fibers from the balls annoying? Or these tiny little things cause any health problems? BTW, the balls I play is the average priced ones like the Wilson US Open, Penn3, Penn2 balls. So it's not a quality of the balls.
