Brisk Walking After 70 Could Slow Brain Aging

A daily walk of about a mile can boost brain regions involved in reasoning and may cut the risk of cognitive impairment by about half; additionally, seniors over 70 who maintain a brisk pace (roughly 2.7–3.1 mph) may have brains aging slower than 90% of peers. Experts caution that walking speed reflects overall health rather than directly causing slower brain aging, and they advocate a balanced routine with resistance, balance, and flexibility training plus varied walking challenges to sustain benefits.
