I have become my grandfather; I have become an old man, if not entirely in spirit, certainly in body.
The value of old men, in part, is in the stories they tell; the problem is that we tell them over and over and over. After a while, people just quit listening.
The answer to the problem is for we old men to get our walkers and wheelchairs in gear and go out and make new stories. The difficulty is that it is hard to make new stories when you want to be home before dark. Heroes quests rarely keep daylight hours.
