Hi Rod,
Sorry to hear about your accident. I think that petey_c's suggestion of teaching is a good one. I'm a retired project manager and I teach at a local college. Mind you, I teach an evening class to adults, one night a week, but here in Ontario, all the electrical apprentices (all the trades for that matter) spend some of their apprenticeship in college. You could pass on some of that ol' broke down electrician's ideas and experience to the up and comers. You seem to have a lot of worthwhile knowledge to share. I'm sure it would be appreciated.
Cheers,
Andy
