Might I suggest a small experiment...just to make sure you know what you're asking for. See how long you can go without a drop of water or food and how it feels, before you put it in writing.
This isn't for you but, I'd like to see everyone that's wanting to kill Terri, the so-called husband, the lawyers, the judges, be forced to do without just as long as she is.
If I were truly in a persistent vegetative state then I wouldn't know the difference. Vegetables don't feel pain..
