When I was in my early 70s, I thought I'd work up to jogging again. Started easy, walk, jog, walk, jog, etc. This went on for about six months, until I got to about 50%. I was using a minimalist shoe. My knees started to bother me to the point where I finally had to stop. The pain and stiffness didn't go away. It got to the point where I was picking up my left leg with my hand to get it into the car like some old geezer! I started searching the web and came up with a supplement containing glucosamine and condroitin, along with a small amount of inflammatories to promote healing. Got gradually better, and in six months the stiffness vanished. I stopped using it, and have been fine since. Sometimes I think about a 5K ;-) A few years ago, my wife developed pain in her hip and knee joints. I suggested she try the same stuff, and, sure enough, the pains went away. She's still using it. This is all anecdotal, of course. I've never had an actual injury, just joint issues.
