“I grow old … I grow old … I shall wear the bottoms of my trousers rolled.”― T.S. Eliot.

That is the least of my problems, although I am shrinking and my trousers are too long. Does everyone shrink when they get old? Will I keep shrinking? I am already shorter than my wife. Now that is a legitimate concern. No one talks about it. Can you help me? Marathons, indeed.
