Gerontology, as defined in the Merriam-Webster dictionary, is “the comprehensive study of aging and the problems of the aged.” Many people confuse gerontology with geriatrics. Whereas geriatrics focuses strictly on the medical conditions and disease of the aging, gerontology is a multidisciplinary study that incorporates biology, psychology and sociology. Because gerontology deals with multi-faceted aspects of aging, gerontology professionals can be found in a variety of industries including health care, government, nonprofits and the business community.
