As we age, our white matter (connective wiring in our brain) can thin and develop lesions.
But good news! It has been discovered that white matter has as much plasticity as gray matter, and can positively evolve, especially with exercise!
In a study of people over 60, those who briskly walked 40 minutes 3 times a week had areas of the brain enlarge, lesions shrink, and memory improve.
Those who did not exercise saw their brain health decline over the 6 month study.
So head on out. Maybe grab a walking buddy like I did?
