Birds and wildlife in my neighborhood. I'm technically in suburbia, but enough old growth patches have been maintained that we have a surprising amount of wild animals that live in or travel through the neighborhood (Massachusetts, US)
Merlin app is amazing for identifying birds at the feeder I put on my back deck. And the rest of the animals, I mentally collect like Pokemon.
Dark healthcare provider humor incoming: When considering these kinds of questions regarding CPR, we actually say, "Well, they ain't getting any deader."
CPR actually reverses death. That's why it only works sometimes and only if provided in a very short window of time after you've died. Nothing that is done during CPR is going to make that worse. So yeah, the reality is that it's a little bit of a controlled free-for-all. It's called "heroic measures" for a reason.
