Study says big-hipped women are smarter & have smarter children

women with fuller, "hourglass" figures seem to be smarter, and give birth to brighter children.

The research, published this week in the journal "Evolution and Human Behavior," indicates hips don't lie. In effect, says the study of some 16,000 women, the smaller your waist and bigger your hips, the smarter you are.

And, McGinnis points out, there's a formula: Divide waist circumference by hip circumference. The lower the result, the better.

For instance, notes McGinnis, Jennifer Lopez's waist measures 26 inches, her hips, 39 -- for a waist-to-hip ratio of .66. The less curvy Keira Knightley's waist is 25 inches, and her hips, 33, for a ratio of .76. Paris Hilton, commenting through her publicist, responded to this article by saying " Uh...nuh-uh."
