Epidemiology and prevention.
Any national strategy of preventing disease and promoting health cannot ignore the implications of social deprivation. As social policy moves away from principles of universal provision and towards greater selectivity, there will be an onus on epidemiology to help identify those who are vulnerable--economically, chemically, and environmentally, as well as biologically. The uncertainty of current knowledge about lifestyles calls for new experiments, not merely observation and disputation.
