I've got 3 tears in my left rotator cuff and shoulder muscles and a blown out left knee.~flyguy

Regarding the knee, flyguy, I can report that I had both my knees replaced last year and the results are wonderful, like being given a new life. The difference is particularly striking when wade fishing and doing the associated hiking and scrambling around crick stream banks. If you are weighing the option of a replacement, my advice is to go for it. ~pfa
