True, but the people I’m talking about are at the top of their fields and can afford to retire anytime. You find this pretty much everywhere with high accomplished people - they don’t want to quit, even when they can afford to. Skilled doctors who keep working, professors who keep teaching, artists who never stop creating - well into their 70s and 80s.
