I never really learned to dance. Now, I don't think my arthritic knees would survibe much danving, especially if any twisting motion were involved. I only manage to play golf anymore by taking 800 miligrams of Ibuprophren about an hour before I tee off and still I'm in pain all the next day. I am envious of you guys who can dance. Before anyone suggests I should quit golf, my doctor has told me that if I quit doing stuff like that, in spite of the pain, I'd probably wind up in a wheel chair.
