I am sorry for your loss. But you/he did the right thing. Quality of life, in my opinion, is everything. He had obviously come to the same decision.

Re living trusts, they are indeed great. They do not solve all problems, but they sure do smooth out the road. My parents had one, which really simplified things for me once they were gone. We have one too, but since we just changed state residences, we have to have another drawn up. Thanks for the AARP hint, I did not know that.

Re DNR's, in my experience, there are hospitals, probably all of them, that will only accept a DNR that is on THEIR form. They will ignore anything written by your attorney, or anyone else...
