        Ok. Nothing in your paragraph contradicts what I said.

        No, the role of time. Higgo James has often stated his belief
that moments in time are really not connected.

        It's the QTI claim together with the claim that an observer is
extended over all times at which he exists. Nonsense, yes.

        Nope. The measure is conserved in the RSSA leading to the
infinite expected value for the age.

        Then take a calculus course. I consider the question a non-issue,
and I just spelled it out explicitly to try to get past it. Some limiting
proceedure is required. Same as always when dealing with infinities in
