Thick as a Brick?

A new study says 'Thick' kids are the smart kids.

The study shows the frontal cortex waxes and then wanes as children grow. It gets thicker in all children -- peaking at about five millimetres -- before beginning to thin. "In the most intelligent group, the initial thickening lasted longer and showed the highest rates of thinning in the teen years," the researchers say.
