I wasn't until I actually started to imagine what the mental processing must be like as you die, in various circumstances. What do you feel and think in a crash? As you're being strangled or mutilated? What's a fatal heart-attack like? Do you ever realise you're dead if you were unconscious as it happens?
Put me through a fair bit of existential crCIA which is actually helping me get on a better track in life. Slowly.
