Doubling up on this thread, something occurs to me. Our docs probably don't have a specific mood state in mind. They probably go based on outcome preferences and priorities; alive, alive+functional, alive+productive, alive+productive+happy... or some derivation of that.

If one of our mood states puts the first or second in jeopardy, well, they're going to try pretty hard to avoid that, even if it squishes happy in the meantime.
