Fast walking in your 80s cuts cognitive decline risk in half, study shows

A growing body of research reminds us that the body and mind age together, and that how we move through the world may shape how clearly we continue to see it. A study of adults in their eighties finds that those who walk at a brisk pace carry roughly half the risk of cognitive decline compared to slower-moving peers — a discovery both humbling in its simplicity and significant in its reach. In an era of complex medical interventions, the humble act of walking with purpose emerges as one of the more accessible tools for preserving the mind's longevity.
