(Spoiler free note to future self when I once again start confusing the different Vonnegut titles: This is the ice one.)

2BR02B is a very Kurt Vonnegut short story about a future with immortal people and very quid-pro-quo population control. Think Futurama's suicide booth. It's gruesome in this Vonnegut style that shows you reality, but in a very specific detached angle. I read it when I was feeling pretty down, and it did a good job kicking me back into a more grounded view, as ill-fitting as that sounds.
