yeah, I think for many of us dudes who have led an active outdoors life there are a lot of injuries accumulated. That's why most of us hobble about in old age . I've done just about everything to this poor body and have ongoing issues with back, neck, hips, shoulders, knees, one mangled foot. Hence the stretching - but first thing in the morning, it's a slow hobble down the hallway and I struggle to bend over and put my pants on. I'm only 60!So if you stay active, eat a good diet, and try to avoid serious injury
