I spent my entire career in high tech, mostly in executive management. I loved it and always pushed hard (sometimes really, really hard). I don't think that had anything to do with my current condition. My wife disagrees with me on that, though
I have undergraduate and graduate degrees in forestry, with an emphasis on mathematics and statistics. During my forestry studies I worked pretty benign field jobs in the summers and during school. I was on a forest fire crew, marked timber (with paint for harvesting), inventoried forests, installed erosion control devices, and planted seedlings. I enjoyed all of it except marking timber, which is mind numbingly boring.
Before that, I mowed lawns and was a paper boy, lifeguard, swimming instructor, and archery range director.
I have lived an active and adventurous life with hobbies of climbing, mountaineering, hiking, backpacking, skiing, biking, canoeing, photography, etc. along the way.
I have had numerous injuries over the years, one of which potentially contributed to my current condition. In 1982 I had a rock climbing accident resulting in serious head trauma. It was almost 2 years before I could return to work full time.
