Hi Dave,
We never communicated but I remember you and it's great to have a solid down to earth guy like you back.
I know that you'll succeed in getting back in shape. Just take it slow and steady and be careful.
I've got some knee issues too (2 surgeries - no replacement yet)
and my shoulders are not acting up too bad these days but I've also had 2 surgeries there (not rotator cuff).
I guess that we pretty well all used to be in good shape, apparently now the best we can do is to be in good shape for our age, LOL!
Welcome back, and hang in there.
