I started in law school in '71 and graduated in '74. So I was training for the Olympics, running or averaging around 20 miles a day and going to law school full time. ↗
I used to try to run five miles every other day, which I worked up to and I was doing it, but I was subjected to my own thoughts for forty minutes without any sensory input, and I couldn't stand what I thought. ↗
