Thanks for your encouragement :) I tell people the only difference between being old and young is, when old, you can do everything you could do when you were young, but you will do it slower, and you will be sore afterwards :) (and you may injure yourself doing it, and instead of getting over the injury in a few days, it will take a few weeks or longer :) ) I remember when I was in my 40's, I thought about how almost all the pro athletes were under 30, except golfers. And when I was in my 50's, only coaches were as old as me (and "senior PGA members"). Now, in my 60's, there's barely even coaches my age, and the only athlete my age still competing with those much younger is the pro golfer Bernard Langer :) I now have arthritis in my right hip, so it just hurts too much to run, so I bought a mountain bike last year and have been trying to do that a few times a week now (just on roads and paved trails; no crazy mountain trails for me)
