It’s the one thing that all (or most of us, I guess) have in common; we’re all here because of what’s going on there. It’s natural to want to talk about it.
It’ll pass; I’m already seeing a lot of non-reddit content on my home feed now, whereas day 1 it was probably 95% posts of the sort you’re talking about.
Yes, CPR is brutal and more often than not ineffective. That TV trope where someone gets a few compressions suddenly coughs and sits up all alive and healthy again is complete BS. Literally never happens.
My wife’s a paramedic and in seven years has only seen someone spontaneously regain pulse after CPR twice - and that’s with a team of highly trained professionals and a whole bunch of fancy equipment.
Still worth trying in many cases though, but it’s certainly not a miracle procedure and not something that should automatically be done in every case.
