Aging changes in body shape 12/13/2010
Many people are concerned with changes in their body shape as they age. Although some changes inevitably occur with aging, your lifestyle choices may slow or speed up these changes. The human body is made up of fat, lean tissue (muscles and organs), bones, water, and other substances. As we age, the amount and distribution of these materials will change. Fat tissue may increase toward the center of the body, including around the abdominal organs. |

Aging changes in hair and nails 12/13/2010
Hair color change is probably one of the most obvious signs of aging. Hair color is caused by a pigment ( melanin ) produced by hair follicles. With aging, the follicle produces less melanin. Graying often begins in the 30s, although this varies widely. Graying usually begins at the temples and extends to the top of the scalp. Hair becomes progressively lighter, eventually turning white. Many people have some gray scalp hair by the time they are in their 40s. |

Aging changes in hormone production 08/15/2010
The endocrine system is made up of organs and tissues that produce hormones. Hormones are natural chemicals produced in one location, released into the bloodstream, then used by other target organs and systems. The hormones control the target organs. Some organ systems have their own internal control systems along with, or instead of, hormones. As we age, changes naturally occur in the way that body systems are controlled. |
