THIS predicts how fast you’re aging.
It may be the most powerful indicator of how quickly you’re aging.
If that sounds strange, let me explain.
In my latest Medium article, I explore a simple, science-backed test that doctors around the world are now using to detect hidden decline in the brain, muscles, heart, and nervous system.
It’s not a blood test. It doesn’t require fancy tech.
It’s the 33-foot walking test — and it could change how you see your health.
Here’s how it works: Measure out a 33-foot (10-meter) path, walk at your normal pace, and time yourself. Divide the distance by your time, and you get your walking speed in feet per second.
THIS Predicts How Fast You’re Aging
Why does it matter?
Because walking speed reflects so much more than fitness, it’s a window into how your body and brain are aging together. Doctors now consider it a “sixth vital sign,” alongside heart rate, blood pressure, and oxygen levels, because it captures integrated performance across nearly every system in your body.
In this article, I break down:
- What’s a healthy walking speed — and what’s not
- How gait speed predicts brain aging, frailty, and even mortality
- 5 other low-tech indicators of biological age
- 7 ways to walk faster, live longer, and age better
You’ll also read about James, a patient of mine whose gait gave away early signs of neurologic disease, long before labs or scans caught it.
Whether you’re in your 40s or your 70s, this test is worth doing — and it only takes a minute.
