A study of nearly 4,000 adults aged 80 and older found that “super-movers” — those who walked much faster than peers — were less likely to develop cognitive impairment or report dementia. The findings do not prove brisk walking protects the brain, but suggest walking speed may be a visible marker of resilience and healthy ageing.
