Some people just enjoy their job. I know several engineers who retired, only to return after a hiatus because they missed working with a team on something they were good at and passionate about. Work isn't always about money.
Right, I can understand why someone might wish to work part time even if they didn't really need the money, but I don't see myself working full time beyond the point where I am fully financially independent from needing to.
