Typically, men get old, they retire and they spend the rest of their lives golfing, fishing, hiking. etc. or sitting in a rocker on a porch watching the world go by.
My brother, although he does golf, does not sit around much. His wife sees to that! He has however always been involved in hockey; most Canadians have tried the sport at one time or another. He has played in leagues for decades and just recently was inducted into the 80+ hockey hall of fame.
The 80+ Hockey Hall of Fame is a non-profit organization which nationally recognizes active recreational players 80 years of age and over. You can get more details at http://www.hockey80plus.com

I just wanted to give a shout out to him because I think it is quite an accomplishment, he may not have the speed he once had but I know he enjoys the camaraderie and social aspects of the game. The games are non-contact so not so rough, but the prowess and stick handling is still there. Congratulations old man!
