My wife has made he wishes to not be kept alive in this kind of situation very clear to me. An God help anyone who would try to interfere with my ability to carry out those wishes, and try to use it for their own political of self aggrandizing purposes.
"My wife has made he wishes to not be kept alive in this kind of situation very clear to me."
Good. And when you say "made clear to you", I hope you mean in writing, with a formal medical power of attorney. If she has just done it verbally, you won't be protected from the "self-aggrandizing" (I agree with your observation about that).
