The question of why women outlive men has been circulating for ages. I'm not familiar with the effects testosterone may have on the immune system. What has been popularly suggested is the fact that throughout our evolutionary history, females tended to outlive the males due to the need for continued nurturance of the young. How this may make them less susceptible to parasites is another issue.
My impression is that SA has become enamored of politically correct junk science in recent years, and are to be viewed with suspicion, if not distrust.

You would be wrong. They've been dumbing down for a decade. They publish unscientific speculation all the time in the guise of "social science" articles.
I still get them, but they are approaching elementary-school level and I suppose eventually I'll have to drop the subscription.
