Model Dead in Paris Apartment

Daul Kim, an international high fashion model was found dead on Friday in her Paris apartment. The South Korean native was 20. She is one of several high-profile South Koreans and another high-profile model to commit suicide in the last year.

It has been shown that suicidal behavior travels through social circles. Interestingly, gaining or losing weight - a preoccupation shared by many, and particularly by models - is also thought to travel social circles, according to a new book called "Connected: The Surprising Power of Our Social Circles."

Could self-destructive behavior stem, in part, from the close social ties formed when models live together in apartments?
