After the Schiavo case, I made it plain to my husband that I did not want to be starved and deprived of water. He was free to divorce me. All I wanted was a comfortable room, an occasional visitor, and a TV with Fox News. If I am brain dead it won't matter, and if I am like this guy, at least I would have some contact with the outside world.
"...what I am getting from this is that if you execute a living will, or simply make an idle comment, some people believe your spouse has the right to kill you."
EXACTLY!
I already know to whom I'm giving my POA for such matters. She's been my friend since we were 10 years old and knows me better than my husband or child ever will. Plus, she'll fight for my life all the way to the Supreme Court if necessary. Literally, I will trust her with my life.
When we were agonizing over whether or not to put my Mama in a nursing facility after a few years at home with a caregiver(she'd been diagnosed with Alzheimer's), my nephew jokingly told his mother that if she got to be a pain in the butt he'd put her in a nursing home. She got back at him, though, when she said, "You mean I'd be someplace where I'd be taken care of, fed, and bathed for the rest of my life? Now, what's the downside to that?" LOL!
