Bruno,
So why is it that from the 3rd person point of view everyone dies?
Also along the lines of the "Let There Be Something" thread, isn't it
also true that a finite set of finite histories, or even a countable
set of infinite histories, is of measure zero in the continuum? If
this is the type of selection that is being made from The Multiverse
(whose measure >= measure(continuum)) to the "initial" multiverse(s) of
your and others' theories, then by the same argument that you use to
show that the probability of dying is zero, doesn't this imply that the
probability of having such an "initial" multiverse is zero?
I may be in over my head, but if my "Let There Be Something" inquiry is
correct, then we're all in over our head.

I believe that the quantum theory does not allow cul-de-sac branches.
I also believe that the Godel-Lob theory of self-reference not only
allow cul-de-sac branches, but it imposes them everywhere: from all
alive states you can reach a dead end.
The Universal Dovetailer Argument shows that the physics (which has no
dead ends) should be given by the self-reference logics (with reachable
dead end everywhere).
I have been stuck in that contradiction a very long time ...
... until I realized the absolute necessity of distinguishing the first
and third person point of views. That necessity is implied itself by
the incompleteness phenomena, but that is technical (ask me on the
everything-list if interested).
The intuitive point here is that you cannot have a first person point
of view on your own death: 1-death is not an event, and should be kept
out of the domain of verification of probabilistic statements. Another
intuition: the finite histories are of measure null among the
collection of all histories (the continuum).
