I’m supposing this has been posed before with slightly different approaches, but…
As predicted by many, after you die you follow the white light to the waiting room, where you take a number.
In the meantime, there are TV screens hooked up to "DVR"s, where you can call up ANY event in human/earth’s history and watch it as it happened (multiple angles too, if need be). There’s enough screens for everyone - no waiting. No judgement is passed regarding what you view.
I’d have to watch the B-29s bombing Tokyo and other cities during WWII. And I’d have to follow Daniel Boone around for awhile. There’s a lot of debate about his life, and I’d like to have a few things settled for myself.
I’d like a few things definitively proven, like Jesus’s existence, what dinosaurs really looked like, what the UFO was that started the whole Roswell bullshit, who really was responsible for various murders currently ambiguously unsolved, that kind of thing. I’d pick dinosaurs first.
I have no expectation that my character or nature will change fundamentally after my death. That being the case, given unlimited options of what to watch, I will probably end up watching Arrested Development and late '90s Law and Order for the jillionth time.
