Hmmmm:

Universities of Pittsburgh and California (Santa Barbara) researchers found that women with “hourglass” figures are more intelligent than women with round or straight bodies, and tend to give birth to children who are more intelligent.   

The hourglass-shaped woman is defined as one whose shape consists of a smaller waist than hips. 

These hourglass-shaped women were found to also produce more intelligent children, which the study concludes is due to having more omega-3 fatty acids stored in their hips, which is not found as much in other shaped women.
