This college student's essay (some months ago) about Terri, and other brain-injured patients, is informed and well reasoned. It is really a pleasure to see students like this offering an uplifting, morally responsible view -- especially in contrast to the debased posturing we've heard so often from purported grown-ups.
And note this remarkable reference:
>> "In 2002, a 31-year-old comatose stroke victim, Mark Ragucci, managed an almost complete recovery through intensive and innovative methods of therapy, procured through the efforts of his devoted wife. His doctor, Stephan A. Mayer, director of neurointensive care at Columbia University's medical center, had previously called the situation hopeless. Ragucci reports that, while in a vegetative state, he was at least semi-aware, and was distressed to hear his caregivers referring to him in the past tense. His own opinion of his quality of life during his coma, therefore, differed significantly from what medical experts assumed. "
This needs exploring.
From your previous link about Chris Barnes, I found an encouraging entry. Chris eating and feeding. Patients are routinely made dependent on feeding tubes, only to have those feeding tubes suddenly removed, causing death. Chris' wife is doing what she can to break his dependence on the feeding tube.
