Estate planning

DW and I have an appointment to sign our wills and other estate planning documents.  We're arranging for our boys' guardianships and the administration of their special-needs trusts, hopefully for the next 50 years or so (and thanks to Gentle Reader Bill here).  We've also got living will and power-of-attorney documents so that we avoid the Terry Schiavo situation.  I still haven't decided which box to mark on the living will.  I suppose that if my condition is terminal and death is certain without artificial supports, I'd rather just get it over with, but I really haven't given it a lot of thought.  Mortality, mortality.
