Be careful because in the process you take the risk of losing a friend.
More aptly (3 1 switch) a friend risks losing you.
Do you agree that at *some* level we do that all the time?
Does death works as personal local and relative memory eraser ?
Your suggestion is risky, if not egoist, but, is there another way
when the rare disease is fatal?
Thought experiment with speculative memory capture raised quickly
the interesting question: how many (first) person exists, really.
I don't know the answer. One ?

Would you agree that a quantum multiverse could play the role of a
particular "open universe where an infinite number of
copies of me exists"?
If you agree, would that mean we have "anthropic reasons" to believe
in a quantum-like multiverse?
