Sorry about your wife, but her condition was different then Terri's. Terri was not dying of cancer. Terri was not dying period until she was denied hydration and nutrition.
Sorry you don't see any difference.
I was not referring to the cause of death, but to the effects of removing the feeding tube. The point is that Terri would not be feeling any more hunger or thirst with the tube than without it.
It is you who doesn't see the obvious: Terri didn't feel anything as she approached her final release.
