I've accepted my own mortality on a deep level. It took a while & resulted in large scale changes to my beliefs & perspective on things.

I think this is very much a spectrum but that most humans live in almost complete denial of their mortality even into the latter half of their life. Most people go through a personal crisis as it becomes apparent their meat sacks are impermanent.

My biggest objection is around the centralised decision making of appropriate treatments & the socialising of these costs. This should all be left to the free markets.
