James H. Fowler, PhD, is an associate professor at the University of California, San Diego, in the Department of Political Science and The Center for Wireless and Population Health Systems, and was named one of the "most inspiring scientists" by the San Diego Science Festival.

Your colleague's husband's sister can make you fat, even if you don't know her. A happy neighbor has more impact on your happiness than a happy spouse. These startling revelations of how much we truly influence one another are revealed in the studies of Drs. Christakis and Fowler, which have repeatedly made front-page news nationwide.

In CONNECTED, the authors explain why emotions are contagious, how health behaviors spread, why the rich get richer, even how we find and choose our partners. Intriguing and entertaining, CONNECTED overturns the notion of the individual and provides a revolutionary paradigm-that social networks influence our ideas, emotions, health, relationships, behavior, politics, and much more. It will change the way we think about every aspect of our lives.

In their writing, [Christakis and Fowler] are endearingly excitable, ranging enthusiastically across science and culture to find gee-whiz insights and unexpected results that support their arguments.
