According to this study, people who get into comas on television almost always end up recovering fully.
Which makes me wonder if that's how people got so convinced that Terry Schiavo would be OK.
But then, as I recall, surveys of the American people said most people thought doctors should pull the plug. It was Bill Frist who was diagnosing her from the video tape, saying things like "She certianly seems to be responding to visual stimuli." (The autopsy would show that she was blind.)
Maybe Frist just watches too much TV.
Who sort of wonders what the point of studying such things is.
