The workers are people who could or would not chose a memory, and because of their normalcy, their condition is interesting and thought provoking. I've recently come to the realization that we have a time limit on how much we can read and learn. Each book we choose narrows our potential incrementally, and ultimately some great minds will be neglected. The workers in the afterlife don't have to worry about it. One woman promises to read a mystery novel that is recommended to her, just as soon as she is done with the world encyclopedia.
Time is no longer an enemy.
The newly dead are equally interesting. Each person responds differently when his or her position is explained, and each response tells us how that person lived and viewed life. Some immediately go for the vacuous experiences they have been conditioned to think of as the heights of fulfillment. For a lascivious old man, it is his visits to brothels. Some people claim to have difficulty recalling even one happy moment, while others have difficulty narrowing it down to one.
