National Right to Life has Advance Directives available by state to download for free. Forget Living Wills. There was an earlier article that has made me believe these are designs of the death cult.

You're right about living wills. Do you know how much legal weight the Right To Life Directive might have. The options listed in the article all seem to have down sides. I wonder if just a straightforward power of attorney would carry more weight. I'm not even sure someone can have your power of attorney unless you're deemed incompetent.
I really wish there was a way to guarantee your protection.
