Since women typically live longer than men, a theory of longevity that only applies directly to extending male lifespan seems to have a somewhat questionable status. The case of women strongly indicates that there’s something else going on. One should establish what that is – and then see if that is sufficient to explain the extended lifespan of males too.

Just to keep things in perspective, you have the same birthday as my mother, who just turned 96. May you live so long as well.

Congratulations.

I only had time to scan the paper but it doesn’t seem like they looked at how senescence – as they generally mean, past female fertility – may be a function of average life spans, meaning that selection to produce sufficient reproductive capabilities connect to average life spans and that may generate non-selected correlations or, in other words, longer potential life span.
