Would love it if football players - pro or otherwise - who are aging without debilitating issues would step up and let us know. Not to refute the issues, but to let us know that some are okay. Or aging within the realm of normal. For example - I have a bad, bad knee. But I never played football - or any other contact sport. It seems to be within the realm of normal aging. I think most people my age do NOT have such bad knees, but I do think it falls within "normal."
