Yup early abuse here too, and often wonder how I survived many of the silly ones, lol. Knee, Ankle, Foot, Back, now other internal issues. Still have a few good years left if we can figure out the meds to let me stay active without stroking out. If not, then I still have some other less strenuous hobbies and interests, but hard for some of us to give up the adrenaline rushes (even the little exercise ones).
