As far as the 50+ thing goes–no one I know (including myself) really gives it much thought. We all achieved the lives we wanted–and we’re happy. Like it or not–everyone was young, and everyone will be old.
Besides, regardless of our beliefs, I think we can all agree our time on earth is temporary–whether we’re a billionaire or a pauper–and my family and I are at peace about where we believe we’ll be spending eternity. Eternity is a very long time, and, IMO, that’s far more important than anything else.
