Thanks! And Happy Gnu year to you, too.
The idea that straightening other things out is problematic for the knee is a little worrysome. I'm working on my right knee now. And I get you with the lazy thing. Already have one activity that keeps me out nights and weekends. I need another time consumer like a whole in the head. But I think the bod just won't hold up on its own like it used to. So it's Gryotonics, pilates, yoga or a gym. And I REALLY HATE weight lifting. The little yoga I've been exposed to has helped, but I don't do it often enough, enough of it, or well enough for what I really need.
Hmmm, kind of like my aikido lately...maybe it's just my flawed character!
