Should be noted that "tomorrow" stands in for "in enough time that we operate in Far mode when thinking about it", as opposed to actual tomorrow, when we very much don't want to die.

Come to think of it, a lot of people are all "Yay, death!" in Far mode (I'm looking at you, Epictetus), but much fewer in Near mode (though those who do are famous). Anecdotal evidence: I was born without an aversion for death in principle, was surprised by sad funerals, thought it was mostly signalling (and selfish mourning for lost company), was utterly baffled by obviously sincere death-bashers. I've met a few other people like that, too. Yet we (except some of the few I met in history books) have normal conservation reflexes.

There's no pressure to want to live in Far mode (in an environment without cryonics and smoking habits, anyway), and there's pressure to say "I don't care about death, I only care about $ideal which I will never compromise" (hat tip Katja Grace).
