Wishes

So the whole Terri Schiavo thing really brought the idea of living wills and whatnot into the public consciousness.
Now my grandfather is at a point where we may have to start implementing the wishes he was always very clear about (ie, that he not just be “kept alive” if he wasn’t going to get better).
So for the record, I’m in that same camp – if I show no indication of an improvement in condition, I don’t want any extreme measures taken to keep me alive. If multiple, unconnected physicians and specialists say I’m not going to improve, I don’t want feeding tubes or a ventilator or any of that. I would much rather die at home with people around me who care about me than in a hospital surrounded by freaky machines and strangers.
Any good wishes for my grandfather would be much appreciated.
