My biggest fear is a sudden retirement. Like one day next week he says, nope, I can't do it any more. That would really floor me. Ugh, this sounds very stupid but I'd rather see him in there giving us whatever he has left as opposed to any other scenario (that doesn't involve a fantasy). So I'll watch his decline gracefully with respect. It'll be hard sometimes, to watch, but behind that I know this is very hard on him, so I temper my feelings with care.
