Thanks for the writeup. If I could choose, I would prefer to know so that I have enough information in my hands. Then you can even decide to not bother with the therapy, if you would. Even a good death requires some planning, if possibile. Setup inheritance properly, introduce young children (if any) to the idea of seeing father/mother dying. If I knew I were going to die soon, I would probably force myself to live. Live more. To breathe deeply and appreciate what's left.

In the novel The Idiot, prince Myshkin tells a short story about someone he got to know that was sentenced to death. The guy sentenced to death did some calculation and understood that death was going to happen into 5 minutes. And he felt that the last 5 minutes of his life were the longest ever: he partitioned the 5 minutes in such a way that enough time was allocated to all the meaningful matters he was willing to think about. Loved ones and the Future, which seems odd but overall has some meaning too. What I'll be after my death?

If that setup were possible, it would be very very useful and meaningful. Enough time to put things in order with the loved ones and to die in peace.
