This guy discusses people not going back to work and gave me a little more sympathy than I had. I'm not so sure about the 9 to 5 office job, but certainly any job that is using up your body. I was lucky, I had a pretty easy work life, until 2000 and we became self employed and I end up with back problems because of heavy lifting. Now retired 4 years, still having problems. Thinking about my dad, he used his body to earn a living, his work career was cut short by a heart attack, very likely job caused.
