There comes a point in life when you say "I've had enough of working and time to enjoy life". I did that coming up 8 years ago this coming Jan 11th and haven't looked back. I've always said "you'll know when the time is right" and sounds like you're more than ready. My very good friend in New Brunswick works for the school board as a lead hand in maintenance and has a pretty cushy job and now 68 and he's finally ready to slam the door. You have to keep active and I do most of the time but there are days when I just say screw it and hardly do anything. Hey...maybe UPS is hiring and you could deliver your own car parts. Maybe then they wouldn't get lost lol
