"You'll be old yourself some day" - NOT amateur radio

My mother-in-law said this about 50 years ago. At the time life seemed to be endless. Now I am 72. 

As Michael Portillo (he was a famous UK politician who now is a well known UK TV personality) said, when you are old every year is a year nearer your end, or similar words. Certainly, I am far more conscious of being old. I get tired more easily and I can no longer do many of the things I took for granted all those years ago.

Things that seemed important at 22 no longer are at 72.
