Knee is better

I wore my knee brace all day today and haven't experienced any more pain. I did a 60 minute Spin tonight without a problem. I have to admit that I am concerned. So much of who I am these days is based on my fitness. I get a lot of satisfaction in my ability to work hard, harder than a lot of guys much younger. But I am over 60 yrs old. Sometimes I worry that it will all come crashing in on me.
