Some of us stay married because we're in competition with our divorcing 1960s and 1970s parents, who made such a hash of it. What looks appealing to us now, in an increasingly frenetic, digital world, is the 1950s marriage.

While at a biological disadvantage in competitions, women - who even make trips to restaurant bathrooms in pairs - are at a clear advantage when it comes to grouping together and the activities that accompany it: gossiping, sharing, bonding, assisting, scrapbooking, and building networks.

With more women in power, the world would be better off.
