The key element is the kid was re-heydrated, Terri was not.
Sorry, but that's just not correct. The pathologist found damage from lack of oxygen and that the nerves were completely gone. Dehydration for two weeks before death won't look the same. If you want to argue that the feeding tube shouldn't have been pulled, I can respect your position. But if you're deliberately trying to ignore the facts, confuse two different things, argue that the pathologist didn't know what he was doing, and insist that she was tracking the balloon with her eyes, count me out.
But my dear Doctor, the only substance that carries oxygen in the body is water.
