Is exercising one of your New Year's resolution?

This info should certainly make you consider it.

Older men and women who exercised even modestly three times a week or more reduced their risk of developing dementia, including Alzheimer's, a study reports Tuesday. The study adds to a growing body of scientific research that suggests exercise is as good for the brain as it is for the body, says Eric Larson, the study's lead researcher.

The findings also hold out the hope that daily exercise might delay the onset of Alzheimer's and thus reduce the number of people with the disease, he says. Alzheimer's, which is increasingly common after age 60, causes memory loss, confusion and behavioral changes. (USA Today)
