Whether you buy it or not it is still true that MOST people do not suffer when they starve to death in this type of situation. It may have been quite uncomfortable for Elizabeth Bouvia but that doesn't change the fact that for most it is not. I am referring to starving not dehydrating which is generally but not always painful. For a conscious person to suddenly have access to water denied would not be terribly pleasant. Since Terri Schiavo no longer has much of a functional mental process I wouldn't expect her to experience much discomfort at starving. Part of the discomfort felt by some is related to anxiety and expectations and Schiavo wouldn't have that issue. How much pain we experience is not purely a physical concern. It is also a learned response so Schiavo's ability to experience pain is different from yours or mine.
