Life is filled with things you think you'd never do, and you may not really know what you'd want in a certain situation until you're in it. I don't suppose I would want to live the way she's living, but on the other hand, if my family wanted me and I knew it, I think that might make the difference.
From what I understand this case alone has caused many file living wills. But my family and his should know that we speak for each other.
