You should have the right to do what you did for your husband. People who want a living will should likewise have that right. I assume you agree with that.
My concern is, and was, the hospital people did not explain what would happen if a person had a Living Will. The name sounds good, so a patient tends to sign it.
This happened with my former mother-in-law’s husband. He signed it not knowing they would let him die, and he became choked, could not breathe, and they would not resuscitate him even though the wife was begging them to, and he died.
