Cathe (and Dawn),
I think you are so right about fitness as the fountain of youth. As I age, I see people my own age who comment on how young I look as compared to themselves. I always tell them that good nutrition and a good fitness level are key. As a I age, sunscreen is becoming a necessity, also.
I agree, though, your skin is very lovely with such a nice even tone. Good genes don't hurt either!
Dawn, I have started microdermabrasion (MegaPeel) with glycolic acid prep. I love it. I've only had one treatment and already see an improvement. But, as I said, sunscreen is a must or you'll undo your progress. I highly recommend it.
