As every good ANTM fan knows, you've got to have a walk. (Come on, don't tell us you haven't worked on yours during the commercial breaks.) But according to scientists, a woman's sexy strut isn't all that it appears and is actually intended to throw men off. Apparently, the sexier the gait, the less likely a woman is to be ovulating. In other words, women unconsciously de-sexy their walk when they're most fertile as a means of promoting monogamy (or at least monogamous parenthood). Their true "fuck me! I'm fertile!" signals are much more subtle and can therefore be perceived only by the man of the house.

Though we suppose a more cynical interpretation of the data could be that a woman uses her walk to make sure she doesn't get knocked up, i.e. so busted, when she cheats. But we want to know whatever happened to the good old-fashioned method of peeing on an ovulation predictor stick and yelling out "Fuck me I'm fertile"?
