A recent report makes "news" of the fact that women are in general, and consistently, capable of less exercise than men. Both the Washington Post[1], and the New York Times[2] report on this story, though interestingly, the Post devotes nearly three times as much space to it. The difference they have found is not huge, a 50 year old woman reaching 8.2 "metabolic equivalents" (METs), and a 50 year old man reaching 9.2 METs, but apparently this difference grows with age. Just a little more proof that men and women are not, as we are told, interchangeable.
