“Are there diseases or complications caused by 4 decades of arduous physical toil, followed by inactivity? ”

I planted over 1,500,000 trees by hand. I also cut hotline with a chainsaw for 29 years. Tree planting is the most arduous job in the U.S. Cutting hotline [not quite as arduous as tree planting] has often meant constant moving and cutting for 14 hours straight. We can take breaks, but I never have, since time flies when you work very hard. I must always stop to eat. I eat 8,000 to 10,000 calories a day. I am strong, have never had an ounce of fat, and have always slept 4 to 6 hours a night normally. When fighting a fire, I sleep between 2 and 3 hours a night. I get little tiny, natural shots of adrenaline for as long as we are out on an assignment. Sometimes for a month straight. I needed to give that background in order to ask my question. I haven't known or read about anyone toiling as long and vigorously as I have. There are, to my knowledge 8 men that have planted 1.5 million trees by hand. What are some things that may happen now that I am doing no exercise? Can it affect E.D. issues to stop moving after that much movement? I can only sleep 2 out of 3 nights, for about 4 hours each night. Not tired. A Urologist said I do not have an enlarged prostate.
