If there is a chance of saving 'me', the me that knows she is alive and has capacity to both feel and give love and life... Then by all means, I want them to pull out the stops to save me. That's what love and gallantry and devotion are all about.
But if I will never get better, if my condition will not only consume me but the lives of everyone around me and all that they've worked for, I'd surely hate to see that happen. Money is often used as just a callous matter where life is concerned. But as long as medicine and care are things that take time and money, it will be an important part of decision. To risk our life and the assets of our whole family for a cure is gallant. To have it all consumed in the care of a permanently vegetative body that used to be me.... is just sad.
I believe that Terri's family prooved she could give love and accept love so according to your criteria she should have lived.
You appear to be evaluating "quality of life" FYI- Terri's medical bills were paid by Medicare after her medical malpractice money was all spent on lawyers in order to kill her. Yeah her Meical malpractice money didn't go for her care it went to pay her husband's lawyers to get her killed. Isn't that ironic.
