A topical discussion of issues of health and health care. Michael Fitzpatrick, in the light of his day-to-day experience as a practising GP, questions the current crusade of government to improve public health and the consequent increase in the level of state intervention in every aspect of people's lives. He concludes that we need to establish a clear boundary between the worlds of medicine and politics, so that doctors can concentrate on treating the sick - and leave the well alone.
