Thanks for the kind remark. Fitness really is worth the time and investment in energy. It paid off earlier this afternoon: I was helping my stepson get his F-150 up on a ramp for an oil change. The truck clipped me and I was knocked arse over teakettle on the concrete floor. Fortunately I was able to bounce right up with no appreciable damage discernible.Yes it does but at least there are things you can do about it. Putting in crowns to save what's left of your teeth might not help in the long term but improving your fitness and strength like Jan Libourel is a way to overcome or at the very least mitigate some of the effects.
