As for how much each Justice does, versus having staff do it, that's personal to each Justice. Though as they get older, Justices tend to leave more of the work to staff. However, all that is after the fact. Cases are actually decided in the Friday afternoon conferences at the end of the week in which the argument is held. Only the Justices are present for that conference.
I don't think the problem is that Justice O'Connor has gone potty. She's no pottier than any other Justice at this time. It is that she's gone round the bend in her jurisprudence. As for health, age and resignations, let's just say I expect to see three resignations within or at the end of this Term of the Court.

Wow.
Thanks for your kind reply.
Three resignations in an election year? I'll believe it when I see it.
