Aerobic activity keeps your brain young A long term study from the University of North Carolina at Chapel Hill School of Medicine finds that aerobic activity will keep your brain young. The brain's blood vessels naturally narrow and become more tortuous with advancing age, but the study showed the cerebrovascular patterns of active patients appeared "younger" than those of relatively inactive subjects. The brains of the less active patients had increased tortuosity produced by vessel elongation and wider expansion curves.
