I also think her husband is being kind of selfish, I mean he has a fiancee and a baby with her (or on the way) Why not just divorce her (there has to be a way) let her parents have the burden of taking care of her and go on with his life?
selfish who do you think has been taking care of her for 15 years... all the money won in their settlement has been used for your treatments... he would like to get on w/ his life, which he should be able to, he shouldn't have to spend the rest of his life worrying about a dead person.

as far as starving to death, it is painless b/c she has not brain activity. the body is working w/o a brain right now, she is no different than a dead person as it is.
