It did have a kind of equivalent to stashes in the mq extension, but its interface was a bit esoteric compared to the rest of Hg, from what I remember.
In the puzzle game series The Talos Principle, intelligent robots (who were made to outlive humanity after a species-ending global pandemic) seem to have the exact same kind of affinity for caring for cats that humans do. It's actually really sweet and cute.
I'm not negative on it exactly, but the idea of not being revived doesn't really bug me. If that had happened, then it's whatever, I guess?
But I agree with your sentiment about using the time we're given. I don't put much thought into what happens after death other than in a purely self-entertainment, "oh that'd be a cool what-if scenario..." type of way. My goal now is to minimize my suffering and maximize my happiness to whatever extent I can. If I can make others happy too in some way as I do that, that'd be neat too.
As someone who once came extremely close to death and was unconscious for days after eventually receiving medical care, my take on death is that it's probably similar to what you're saying about going under for surgery. I'm somewhat neutral to mixed on having been revived, but I no longer fear death. I still have a fear of suffering and having painful final moments, but death itself seems peaceful if nothing else.
In terms of something happening after death, my only real thought on that is that it really troubles me that I came into existence in the first place and that I experience anything at all. I sometimes wonder if that was truly a one time thing or if it's something that could happen again.
