It's more realistic than living forever: having a continence forever. A constant memory...
So whose memories would you get, mom's or Dad's? What if they don't agree on things? What if they get divorced?
"Your honor, I want her memories expunged from our child."
Very cool. Here's another spin:
Let's say the "constant memory" works. Any time you want, you can have all your memories transferred to your fresh young clone. Poof, new young you.
Let's say that for strong reasons (probably technical, maybe legal), once you've done this the old you can't hang around any more.
Would anyone voluntarily live past, say, age 40? How old would you permit yourself to be if you could become young again (a kid, a teenager, whatever) at only moderate cost and inconvenience?
How different would the world be? And what sorts of new problems could we get from that?
