When I say that everyone is immortal under QI, I mean that a copy of every person survives to any arbitrarily large age. This is not because each near-death experience is quantum in origin, but because in MWI there is continual duplication due to random quantum events. Every copy inevitably dies at some point, but with new copies continually generated, some will survive indefinitely. Not that this is anywhere as much as many copies as people fear, because quantum events only give rise to world splitting if the effect is magnified to be of macroscopic, decohered, significance. That does not happen for every random neutrino that passes through your body, although there a a very large number of scattering events that could happen for any such neutrino. But none, even if there is an interaction in your body, ever becomes macroscopic. But this is irrelevant to the argument from relative measures.
