Dotsie, you are sooooo right about our generation paying the price for the fittness boom. About 7 years ago, I was living in an apartment temporarily as we prepared to relocate to TN. There was a group of ladies that met twice a week in the clubhouse for aerobics. Well, since my apt. was on the 2nd floor, I didn't want to do my usual workout tapes as I had done when I was a 'homeowner.' I had visions of the neighbor below banging the ceiling with a broom handle!! I have worked out since my 30's and so I didn't think anything of joining the class. I'm not a fan of group exercise classes although I taught one for time. I thought - what the heck, I'd give it a try. Well, I was old enough to be their mother. I managed to keep up with them which was no easy feat - but truth be told it about killed me. On the last night of class - for reasons unknown - I landed on my right leg in an odd position - and the pain shot thru my knee like a knife. I have not been the same since. I believe I did some real damage - but, chicken that I am - have not seen a doctor. It will no doubt have to be addressed one day. I still work out and try to 'baby' it, but it will wake me in the night with that searing, shooting pain on the inner knee. I think it's tendon damage - but, did I mention that 'chicken little' thing about seeing the doctor?!? I do know several gals my age that have had knee and hip replacements and hope I won't be needing anything that drastic for a long time.
