You include lots of undefined terms thrown in there. "brain-damaged?" "no hope of recovery?" "artificial means?" A feeding tube is ipso facto no more artificial than a catheter. That it took her as long to die after being deprive of food or water as it would you or me ought to tell us something.
Terri had a surgically implanted feeding tube. Different than an oral feeding tube.
If Terri had put her wishes in writing, would that be euthanasia if her feeding tube were removed? You're dodging my question.
Yeah, I guess if they removed a catheter and foley bag and waited until her bladder burst and she died of sepsis, that would have also been OK.
