LIFESTYLES: Dr. Marc Graff, a Reseda-based psychiatrist for Kaiser Permanente, said the American work-based culture also has psychological implications. The emphasis on work has created a situation where people build their identities around their jobs. With little leisure time for family, friends or getting involved in the community, people have become increasingly isolated, he said.

``These days, people belong to nothing,'' he said. ``Work is the one thing they do.''
