It's martin luther king jr.'s birthday, and Hans Breiter, director of the Motivation and Emotion Neuro-science Center at Massachusetts General Hospital, has the day off. Sort of. He's sitting in his home art studio, gluing together a statue that broke soon after his 9-year-old son made it.

Breiter's life is a blur of family and research; he jokes that skimping on sleep is the only way he fits it all in. But ask him if he's a work addict and he becomes stone serious.
