I read the piece, but I still disagree. Perhaps the form of the living will is something to be considered rather than discarding the idea of a living will altogether.
The living will I have is quite simple. It states clearly what I want withdrawn and what I do NOT want withdrawn. One would have to do significant backflips to interpret it in a way different from what I intended.
But of course, one could do the same with the Patient Protection document.
You should not use the proffered “Living Will” at all, ever. Don’t use anything labeled “Living Will.” Leave your intentions with your attorney and your relatives.
