I have every intention of going ahead with it. I don't see any real choice.
My problem is, paradoxically, I have been so lucky with my health for the first 70 years, I've never gotten used to this kind of thing.
I have another worry: If the procedure involves stopping your heart to work on it, and using an artificial heart for a short time - before a flat EEG was the criterion for death, the classic one was the heart stopping. That would imply that I would be dead for a short time during the procedure.
So if it goes well, and I recover, am I legally a zombie?
