When my grandfather retired & he & my grandmother moved to Florida he got a job at Public as a grocery bagger. He did not need the money, but he loved & missed his old routine of getting up, dressing nicely & interacting w/ people. He loved talking to people as he bagged & took their groceries to their car. He loved people & gardening.

:-) Same as what one coworker told me. Essentially, he quit retirement. He said retirement was bad for his health, so he took min. wage jobs just to keep working.
