If you had a work ethic prior to retirement chances are it will stay with you for life. Something a lot of the young don't seem to have now days. A good friend was forced by his employer to retire because they thought his Parkinson's posed a hazard at work. Now he spends his time in his wood shop making puzzles and toys for kids undergoing cancer treatment. He made wonderful furniture (I had him make my wife a few pieces) now he works for his own satisfaction and gives his stuff away at the cancer clinic. I think he still gets up a 5 or 6 in the morning to take his meds, so he can be in shape to go to his garage/shop each day.
