I started because I couldn't play college ball because some fella decided to play tackle football on me during touch-football. Whenever I thought I was done, I would watch a rec league game and tell myself, "I could do better!" Then I would get back in.
In my later years, I am starting to see this as a good way to excercise (as was mentioned earlier), but also as a way to work through retirement

. I don't see my Social Security check being very big and by the time the politicians run the economy in the ground, my retirment pension will get me a bowl of chillie - each week!
I love the game, too! But I don't love the crap! Getting paid balances it all out.
