*nods* My Dad had a living will, but he never contemplated having brain cancer that attacked his language ability, leaving him conscious and semi-mobile (right-side paralyzed) but unable to speak, write, or communicate, for months on end.

It would have been so much easier if there were a clear-cut situation, but there so often isn't one. *sigh*

I do know where you're coming from as to the ambiguity and the fear of making medical decisions that could result in brain death/coma/etc. It's a hellish place to be.
