I congratulate myself for never having engaged in the type of sports in my prior life that would limit me in the future. I know folks from my college days who played Big Ten football (very well, but not well enough to make it to the NFL) who can barely walk today.
I can't imagine what it would be like to be my age, or even considerably younger, and have the limitations you see with many NFL alumni. Was it really worth it?
Good on ya! Me and my fellow athletes, and those of us in the military who have been put thru the boots, are hurting!
All my old HS friends and other I know who were not athletes when young, are all running marathans, 1/2 marathons, doing all sorts of hikes and things like that. Ill keep creaking along.
