What's the Name of That Book??? discussion

Cannot for the life of me remember details of the story itself, just this little bit of it; read it sometime in the 1980s, but I have a feeling the book is much older. Set in the distant future, the way mankind travels between the stars is to record their memories/personalities to a computer, then their bodies are either flash-frozen or destroyed. When the ship reaches its destination, the recorded memories are uploaded back into the bodies (or clones thereof). The process of freezing/destroying the bodies is excruciatingly painful, but since that part isn't recorded, nobody that undergoes the process "remembers" it. The main character is somehow immortal, and amuses himself over the course of centuries by re-mixing and altering the recordings of his companions' (at least one man and woman) memories and personalities, living out a period of time with them, then putting them back in storage and repeating the process.

It could be OSC's _The Worthing Saga_ (also _The Worthing Chronicle_). Differences? MC is not immortal - but lives many, many human lifetimes, (view spoiler)[by putting himself into cold-sleep often and quickly (during the end of the story when playing with other's memories and personalities). The reason he's doing this, is because he was taking a bunch of people to colonize a planet, and their memory recordings got hit by an asteroid... so full-grown bodies, no memories. So he re-trained them, gave them experience living, and took the best of them (smartest, etc) to put back into society later. (hide spoiler)].

The Worthing Saga by Orson Scott Card for Justanotherbiblophile's suggestion.

Karen, are you still looking for this or did you find it?

No response, moving to Abandoned.
