So you have personal experience with this as...? I worked with hundreds of these type of patients (and she was not PVS) for thirty years. Believe me the mind has lots of control over the body. If she was depressed and wanted to die it would have been over quick.
It's amazing how well one can adapt and even become happy in a situation such as Terri's especially if she had received some sensory stimuli. In my experience the survival instinct is very strong in most people, even under the most adverse circumstances.
But if she was PVS as so many believe then she didn't have any awareness and as such couldn't be suffering. So why kill her?
Oh I get it, it's for OUR convenience.
Because that was what she wanted. As would I. And, if you are honest, as would you. She was displayed for years as a foolish debilitated creature, lower than a monkey or a dog or a cat. She never, ever wanted that. Nor would any of us. If you weren't so wrapped up in ideology, you would admit that for yourself. No one -- no one -- would want to live that way.
