Seventy-plus years and still going! Air Force, industry, teaching (at all levels—three degrees), government and freelancing. But retirement is best, as I hope you will find.
When I had more energy I built my own home and looked after a very big vegetable garden. Nowadays I like to read, write, travel, play a Clavinova, talk with my children and grandchildren and think. (Probably thinking comes first.) I’ve written technical and travel articles, training programs and a long autobiography.
