Aging occurs at different rates in individuals. These rates are influenced by factors including genetics, lifestyle, and health. Midlife is considered to be the central period of one’s life, consisting of individuals who are approximately 45 to 65 years of age, although some researchers suggest midlife consists of individuals who are 40 to 65 years of age. There are a variety of changes that occur throughout life. However, a majority of the changes that occur during midlife are considered to be normative physical changes. The physical changes in midlife include but are not limited to changes in appearance, senses, muscles, joints, and organs.

Additional Information

This is one in a collection of essays as part of a project that began as an encyclopedia of developmental psychology coordinated by Dr. Randall Summers. However, for unforeseen reasons, the publisher was no longer in a position to publish the encyclopedia. This project was undertaken so that thousands of hours of work by psychologists would not go wasted. Enjoy these essays and feel free to cite them using the proper format.
