I guess I'm curious as to how they've been able to fend off bedsores for all this time. It's a major concern for anyone bedridden for more than a few weeks.

There is ignorance and cruelty here. Ignorance on the part of a lot of commentators who are parroting positions rather than truly informing themselves as to Ms. Schiavo's true condition. Cruelty both to her parents in harboring their wishes and giving them false promise, and cruelty especially to the impugning of the husband.

I suspect that Ms. Schiavo herself has long been 'out of it' and has no conscious awareness whatsoever.
