I think I get less upset about this sort of thing than many people. But even given that, I don't think either of us is the sort of person to say 'I get upset' without having a bit of a poke at 'why, logically, should it be upsetting?'

Incidentally, if I were told I had a choice between my life ending tomorrow, and my life ending in three years after a great deal of pain and suffering, I'd be very tempted to take the former. It wouldn't be a straightforward choice; ideally I'd want to know more about any upsides of staying alive for those three years. But simply 'not being dead' wouldn't be enough of an upside to swing it for me.
