I'm not convinced that people don't fear death. It's hardwired into us. It's easy to say that not existing any more ain't no thing when you're 20 years old and invincible with the world at your feet. When you're older and there's so much you could have done, I don't doubt there's not a one among us who wouldn't ask for just a little more time.
Anyway, I'm mostly agnostic really so my thoughts on the afterlife are a bit muddled. I don't really believe in a god so i expect death to be very much the last stop on the tour. I live my life trying to do the best I can by others, so if there is a god I'd like to think they'd judge me on my actions (and my intentions) and let me in to experience the good stuff. If they're a god who'll punish me for not praying five times a day/going to a specific building once a week/whatever despite being an okay guy, well, that's not a deity I want to do business with anyway.
What I'd really like in death is a little post-game report. A "game over lobby", if you like. I'd want to be able to look over all the statistics of my life from the mundane all the way up. Anything you could think of: distance travelled, number of different people met, number of hamburgers eaten, total amount of drugs taken/alcohol drank etc. It'd be nice if you could go over situations in a play-by-play style too, and ask questions. If you could ask "What was this person really thinking here? What would have happened if I'd done x instead?" Sure, you might find out a lot of stuff that would have been more useful at the time but what can you do about it? You're dead.
That nice little review lobby would be nice, with the option to say "That's it! I'm done here!" and check out once and for all. Yeah. That'd be nice I guess.
