Brisk walking is a simple measure, but it can open a useful conversation about brain health and staying independent with age. After cancer treatment, I’ve learned that everyday function matters as much as the scan or lab result—and belongs in preventive care.

Correlation doesn’t establish causality

Or, people who are healthier into their 80s have both better bodies (ie can walk faster) and better brains. Harvard ought to know that correlation does not equal causation.

Good one to surface. The autopsy data is what stopped me: same dementia pathology in the fast walkers as everyone else, but better cognition in life. Resilience to disease rather than protection, which is a very interesting story. Worth adding that super movers were defined as people already walking fast at 80, and the authors note they were healthier going in. So pace reads as evidence of a well kept system that made it all the way to their 80s. Which makes it highly informative. What can we do today that keeps us able to walk like that at 85?

A brisk daily walk might be one of the simplest long-term investments in brain health. Small habit, potentially big payoff.

@okiraul1 @assumptanakintu see how i could win without even trying.

That makes sense. A brisk walking pace helps support healthy circulation and cardiovascular fitness, which can benefit the brain and overall health. Pairing regular exercise with a nutrient-dense diet provides the vitamins and minerals that help support these processes.

if you’re a fast walker, it's only because you can't afford gas. public transportation in America is a joke and a new car with insurance spies and cost as much as a house payment

Worth pairing with the reverse-causation data. Buracchio, Arch Neurol 2010;67(8):980 - 204 seniors followed up to 20 years: gait speed decline accelerates 12.1 years before MCI onset. Slow walking can be an early sign, not only a cause. Verta zinoti.

Every step we take is a sign of good health. Aging does not mean dimming our passion for life; staying active is the best gift we can give our future selves. May we all walk steadily and go the distance, enjoying a life that is both healthy and vibrant

Hits like a thought you sip, not say.

Here we go again says non adult person who stay indoor or only go out with automatic self driving vehicle. Making your life harder now doesn't always mean it become easy later.
