Hair and style

Battushig Myanganbayar, a freshman at the Massachusetts Institute of Technology (MIT) from Mongolia, asks me, "Have you ever heard of the 'Freshman 15'?" He's referring to the storied 15 pounds students often gain in their first year of college. Not only is he heeding his mother's warnings about pizza, but he is also doubling up on required physical education classes, taking two per semester.
