Leopold Von Ranke

You have reckoned that history ought to judge the past and to instruct the contemporary world as to the future. The present attempt does not yield to that high office. It will merely tell how it really was.

I don't feel any different than I did when I was 40. But I realize mathematically, I'm equidistant between that and 80. I'll keep doing this for a while, but I'm not going to be one of these people who hang on just for the sake of being on the air.
