This booklet introduces the concept of health promotion and disease prevention, outlines the health risks that are found in daily life, and shows how the risk of disease and disability can be reduced with minor changes in life style. Information is given on the number and causes of yearly deaths and the measures that have been taken by the government and by individuals to reduce the risks to good health. Heredity, environment, and life style are discussed in relation to good health. General suggestions for all age groups are to eat sensibly, to exercise regularly, to avoid addiction, to be safety conscious, and to learn to handle stress. Specific health risks and suggested healthful practices are discussed for infants, children, adolescents and young adults, adults, and older adults. Concluding this document is an appendix listing 62 government agencies and private, nonprofit groups which are sources of information about various health promotion and disease prevention activities.
