The principal health-related killers of modern man--heart disease, cancer, stroke, and accidents--are best described as lifestyle diseases, for the etiology of these killers includes the abuse and neglect of the body. Health depends essentially upon the control of environmental influences, including those aspects that the individual creates. Individual responsibility in preventive health care requires: (1) giving up cigarette smoking; (2) getting enough exercise and rest; (3) maintaining proper weight; (4) adhering to a low-cholestrol diet; and (5) following medical advice. Death from accidents can be reduced by a decrease in negligent behavior. Health education programs must be improved and offered throughout the nation's public schools. A breakthrough in the education and motivation of people for healthier lifestyles has been found in the Health Hazard Appraisal (HHA) listing. The HHA listing offers individuals the opportunity to examine their habits and health in the areas of: smoking; drinking; motor vehicle safety; water safety; blood cholestrol; blood pressure; blood sugar; physical activity; and drug use.
