After you die you do your life with new sorted by functions.
(from Sum: Forty Tales from the Afterlives)
In the afterlife you relive all your experiences, but this time with the events reshuffled into a new order: all the moments that share a quality are grouped together.
That’s the first line. From there, it becomes a list of what you relive and how long. Simple, short, brilliant, weirdly blissful. I heard this story read by Jeffrey Tambor on RadioLab recently, which is what prompted me to go out and buy the book. You can read “Sum” here. But I also recommend you check out the “After Life” episode of RadioLab and subscribe tot he podcast. It turns me on to interesting things all the time.
