well I managed to hunt and hike till I was 64, at 65 my hiking days are over like I use to do, Knees are destroyed, I walk OK now but no more heavy stress on the knees, my old partner and brother invited me to hunt Arizona, in a blind near a water hole, drive up in a truck and hunt LOL, The meat will have to be dispersed to family and friends, I can no longer eat meat, due to bad kidneys from abuse, and damage from the dam hospital, LOL but it's a small matter, I am still walking, had to sit in a wheel chair twice, and never again. life moves on.
