Health is a state of physical, mental, and social well-being. It involves more than just the absence of disease. A truly healthy person not only feels good physically but also has a realistic outlook on life and gets along well with other people. Good health enables people to enjoy life and have the opportunity to achieve their goals.
To achieve and maintain good health, people must have basic knowledge about the human body and how it functions. Only then can they determine what will or what will not help or hurt their health. Learning about health should be a part of everyone's education.
Society as a whole benefits from people's good health just as individuals do. For that reason, many government and voluntary agencies strive to preserve and improve the health of all people. The World Health Organization (WHO), an agency of the United Nations, works to promote better health throughout the world.
