Tennis the Next 50yrs?

Hit 53 and still running around the asphalt. Yes there is wear and tear but it's worth it, at least for now, or is it? How do the ankles hold out if you keep playing? The knees, back, etc. Do the Bennifts exceed the cost? Would like to hear from the old die-hards who are still out there making it happen. Thanks

Have a fews years on ya and tennis has kept me alive . . . went down with a heart attack last November with 3 arteries over 98% blocked and the doctors said the only reasons I lived were . . . one, I went down in the doctors office and . . two, TENNIS. For almost 50 years I've played, taughted or coached tennis almost every day and many many days I'm on the courts two or three times in a day. Playing so much tennis, my arteries had developed little capillaries around the blockages and that kept me going . . . I ended up having quad-bypass and missing four month of tennis while the breast bone healed but within 6 months I was back playing tournaments and teaching tennis again. Cost? I've made tons of money over my life teaching, working summer camps, giving lessons, and coaching high school teams . . . tennis owes me nothing . . . it has kept me going! I play asphalt tennis only about 2 or 3 times a week but most of my time is spent on clay courts so that helps the knees and back . . . you have to keep the weight down . . . stretch . . . do other workouts (I swim 1/2 mile at least twice a week and spend hours in the weight room) . . . watch what you eat . . . take the vitamins . . . have a weekly massage . . . etc. Ankles have never been a problem but I'm real careful about the shoes I use (only once in a tournament did I roll and ankle and have to stop and that was over 25 years ago . . . knock on wood). During the winters I go to Florida and will cut down on the tennis a little as I'll play my new love pickleball for 2-3 hours every day and tennis only about 5 days a week.
