This work explains a new field of scientific research, exploring how psychological and emotional factors influence health through their effects on behaviour and the immune system. Martin analyzes how the brain and the immune system interact, and presents new evolutionary biological perspectives on some fundamental problems in the realm of health and sickness
'Compelling... Balanced and impressively up to date... The tone of voice, the open-minded but critical intelligence should uplift the quality of the debate... Martin's lucid account of possible mechanisms of the connections between mental states and personality traits and illnesses is a notable triumph of his book... Excellent.'
