I disagree. Kate Adamsons husband was told the same thing and so was Sara Scantlins family. Adamsons husband was told to pull her feeding tube, there was no hope and she heard every word. Have you gotten to hear her story? There is just too much that we don't know about the brain. It's mans most complicated organ.
But beyond that. I disagree with euthanising someone who only needs a feeding tube.
The CAT scans of Terri's brain in the 1990's aren't like medicine in the 1800s. It hasn't changed that much since then. We were pretty high-tech even during the Clinton years.
But I think it's worth checking out with newer technology before a final decision is made.
