That's a crap analogy since someone who needs resuscitation isn't capable of saying "save me!". It's not possible for there to be any conflict between previously stated intention and present demand.

While there may be individuals who would want a "don't give me food/water, even if I beg for it" clause, you don't have to agree to such a thing to do VSED. And regardless of what you've signed, palliative care should be there to deal with any pain/anxiety/whatever the patient is experiencing during the dying process.

>however if you have signed that you do not want that to happen it will not override what you signed when you were "of sound mind"

That statement is not supported by the material you linked.

Oh, goody. More Beach Curls History.
