Related: someone in my family had a lingering, awful, bed-ridden death over last 6 months of his life. I've vowed not to let it come to that, but however the end manifests there will still come a final hour.

I imagine what I'll be like in the final hour, how I'll feel. Then I'll wonder: what could I do now that would make future me most satisfied in that final hour? And, whatever the answer to that is, would maximizing for that lead to a better life? By what standard could you even answer the question?
