Yet another reason to exercise: the bigger the workout, the bigger the brain.
Here’s good motivation to get up and move more, even in the dead of winter: a new study published in the journal Neurology found that people who weren’t as physically active in midlife had smaller brains than their peers 20 years later.
In the new study, the researchers looked at 1,583 men and women who didn’t have dementia or heart disease. They worked out on a treadmill to assess their fitness levels. Then, 20 years later, the people in the study did another treadmill fitness test and had brain scans.
