I think you can add me to the ASSA camp :)

How does the fact that you're not experiencing childhood provide
evidence that ASSA is incorrect, as chances of experiencing childhood
or adulthood are both significant so I don't see why that would rule
out ASSA ... I kind of expected a different definition for RSSA as this
definition does not even solve any of the crazy paradoxes ASSA has ...
Well, anyway, time to look up the time postulate :)

Also, do you believe one can convince oneself of MWI (versus CI) by
performing a quantum suicide ?
