Please quit spreading bad information, if you got tennis elbow then it was from something you were doing incorrect. You sure change your story a lot because I remember you posting in the past that you got TE from using wilson K-gut string. I guess you change the story to fit your latest argument. Nobody said you can turn the clock back but you sure as hell can delay it. Its funny so many of the guys at my club ask me how can I play so often but rarely if ever am i injured. These guys are in their 40's so i am 10 years older than most of them, but yet they are always fighting injuries. Most have office jobs so they get little if any exercise at work then they come out and play tennis a couple of times a week at a pretty high level but do no other training and they can't figure out why they keep getting injured. I just tell them that they are an accident waiting to happen and if they don't start doing some strength training and exercise outside of their tennis then they will just keep getting more injuries more often. Its just the way it is and if you are not smart enough to understand that and obviously have not researched the huge amount of information out there that proves this beyond any doubt then you are just missing out, but don't spread your bad information to prevent others from missing out on years of injury free tennis as they age.
