If it's any consolation, her body will die of dehydration not starvation.
:-(
[edit:] [link|http://www.sptimes.com/2005/03/19/Tampabay/An_image_to_make_stom.shtml|St. Petersburg Times]:
The heart of the issue for some is whether Schiavo will suffer as she dies after the feeding tube is removed. [Stephen] Mernoff says she will not.
"People think that's a terrible way to go, but that's because they think of starvation as it would feel to them, people who are totally conscious and aware of their surroundings," he said. "In a case like this, however, the patient will feel nothing at first, then will experience renal failure, lapse quickly and painlessly into a coma and then expire. It is actually very peaceful."
FWIW.
Cheers,
Scott.
