“You don’t want to fully retire, D. You’d go nuts, and so would your loving wife. Hang on, even if it’s part time. My dad finally quit teaching Physics on line to college kids when he was 88. You have a long way to go” — JohnA RE: DFO’s 67th birthday this coming Sunday.

DFO: Many have told me that I’ll know when it’s time to retire. Others say that ain’t necessarily so. Still others, like John, offer encouragement to keep on keeping on, at least part time. What say you?
