Let me state one more thing and I'll let this go; I don't mean to be a pest.
I don't think that the recognition that one is getting old means that one must start slowing down or that one's attitudes should be determined by one's age.
On the other hand I fail to see how simply recognizing that one is getting old will make one change his attitudes either. It seems to me that some of you folks think you have to deny being old in order to avoid acting old, whatever that means to you, somebad bad evidently.
I, on the other hand, have no preconceived notions of what acting old is supposed to be or how one is supposed to feel when old. I'm the same fella I've always been, just older.
