Exercise Helps Both Body and Brain
A fit body at 50 may mean a fit brain at 90. In 1968, researchers recruited nearly 200 women—their average age was 50—and, using exercise bikes, assessed and ranked their fitness level: high, medium, or low. During the following 44 years, the women (a small minority had diabetes) underwent tests for dementia six times. Only 1 in 20 of the highly fit women developed dementia, compared with 1 in 4 of the moderately fit women and 1 in 3 of the least-fit women. There’s more: The few highly fit women who developed dementia did so around age 90, an average of 11 years later than the moderately fit group.
