When I was 20-something, 30, I fell down a flight of stairs and hurt my back. I went to a therapist who said don't get out of bed until you do certain stretches, and I've been doing them ever since. I guess I'm the original yogi.

I figure I'm just one of many people. I'm not that different from anybody else, and I don't have great language, highfalutin' language - I'm very ordinary. So I figure if I write about myself, other people with similar feelings and experiences would go, 'Oh, that's me.'

You can get the best out of people if they're happy and not worried or not frightened that they're going to make a mistake.

I've lived through the Great Depression.
