The Footless Crow blog has a beautiful piece by David Craig on finally stopping climbing as age takes its toll:
"My first rock-climb was on my 20th birthday, October 7 1952. My last was on May 19 2011, when I was 78 - although I'd had a gap (to put it mildly) from 1952 to 1973. I know I won't climb again and I'm not being all stoical or mellow about it. Really, inwardly, I'm groaning and keening as all that long experience of effort and delight has reached its terminus at last."
