Geriatrics is that branch of medicine which Senior Health dedicates itself to the care of older people. It is a specialized field wherein a set of specialized physicians seek to provide health care to the elderly. Aging is a natural process which involves the gradual reduction of the body’s organs and their functions. Even as children are growing up, their bodies are aging. At a later time in life, the aging process intensifies especially between 60 to 75 years. The social and biological characteristics of every age group differ as does each individual’s body make–up. The social and biological characteristics of these three groups differ so much from each other that this categorization appears meaningful. It is not to be overlooked, however, that some humans look old well before they are even fifty.
