A new Stanford study analyzed the biological age of 11 organs. The brain was the strongest predictor of mortality.
Researchers built aging clocks for the heart, liver, lungs, kidneys, muscles, and immune system… but none of them predicted lifespan as accurately as the brain.
People whose brains were “older” than their chronological age had a much higher risk of death even when the rest of their organs looked healthy. Because the brain controls almost everything that keeps you alive - metabolic stability, inflammation, memory, autonomic function, mood, movement, hormones, and cardiovascular regulation.
When the brain ages faster, the whole system ages with it. When the brain stays young, you do too.
Protect your brain: sleep deeply, lift weights, challenge your mind, manage stress, stabilize blood sugar, reduce inflammation, and stay connected to people you love. Do it for your longevity.
