A new study suggests one way to avoid the risk of developing Alzheimer's is to build up your muscles.Researchers at Chicago's Alzeimer's Disease Center found that older people who work out and maintain muscle strength are less likely to lose their mental functions or develop Alzheimer's.

One doctor says it's an example of how important physical well being can be to seniors.

The people involved in the muscle study averaged 80 years of age. Only one-eighth of them developed symptoms of Alzheimer's.
