‘You’ve come a long way in the bedroom, baby’

Riffing on Virginia Slims’ old slogan about women’s smoking habits, women are rapidly gaining on men in the infidelity department.

The effect is most notable, interestingly, among oldsters. From 1991 to 2006, the lifetime (note that, please) infidelity rate among men older than 60 moved from 20 to 28 percent, an increase of 40 percent. For women, it jumped a whopping 200 percent from 5 to 15 percent.
