I understand your feeling. Having had a heart attack at 37, triple by-pass at 60, double by-pass at 70, and now, at 80, on kidney dialysis 3 days a week, I sometimes don't feel like doing anything. On other days, I go down stairs to my work shop, and work on carburetors to keep my mind and body active. look at it this way, we are still here, while others are gone. Be thankful, life is tough, but just keep on keeping on.
