This is one of those books that can shift perspectives and change one's attitudes to major issues. Lots has been written about Marmot's work and I won't repeat the main arguments here. Just to say that Marmot focuses on the often poorly understood world of the psycho-social - a world interrelated with but also different from the worlds of individual choice, genetic predisposition, and the incidence of disease. As someone working in the fields of psychotherapy and in community health, I really hope that this book and the results of other epidemiological research continues to develop and to have a meaningful impact on government policy.
