I'm only 28, but I would think it good sense to discuss end of life logistics when you're getting to that age. Not so much about pulling the plug, but living wills, funeral arrangements, policies and whatnot. It's good to have people walk you through different options. I had to deal with that when a close relative died and there's a lot to sort through there.
You make it sound like forced euthenasia, and I see no such thing.
So goes another rediculous post by JennySquirrel.
