Walking linked to mental function

Walking linked tomental function
Women who walk regularly are less likely to experience memory loss and other declines in mental function that can come with aging, according to a study of nearly 6,000 women age 65 and older.
Subjects were tested for cognitive ability once and then again six to eight years later.
The women who walked the least were most likely to develop cognitive decline: 24 percent had significant declines in their test scores, compared with 17 percent of the most active group.
The least active women walked an average of about a half-mile per week, while the most active group walked an average of nearly 18 miles per week.
Walking included exercise and walking as part of daily activities.
