If you’ve ever wished you could simply talk your way into a longer, healthier life, science may have just handed you the world’s easiest cheat code—and yes, it’s as simple as flexing your vocabulary.

At a Glance

• Verbal fluency—your ability to rapidly recall and use words—predicts longevity better than exercise or even healthy eating habits.
• People with higher verbal fluency can live up to nine years longer than their less chatty peers.
• Major studies, including the Berlin Aging Study, have cemented this finding with decades of real-world data.
• Experts caution that while talking well is linked to living longer, it’s not a guarantee for individuals—but the population-level connection is robust.

Verbal Fluency: The Secret Sauce for Longevity?

Imagine a world where crossword puzzles, witty banter, and a love of Scrabble aren’t just signs of a sharp mind, but also predictors of a long and healthy life. This is not a late-night infomercial—this is the surprising conclusion emerging from serious scientific minds. Researchers digging into the Berlin Aging Study—one of the most ambitious long-term studies of aging—found that verbal fluency stands out as the cognitive skill most closely tied to how long you’ll stick around. Forget torturing yourself with kale smoothies; it’s time to dust off your thesaurus.

Verbal fluency predicts how long you’ll live

While doctors and lifestyle gurus have long told us that running marathons and eating chia seeds are the keys to a long life, the latest research flips the script. In 2024, a study published in Clinical Psychological Science revealed that people who scored higher on verbal fluency tests—those quick-fire quizzes that make you list every animal you can think of in a minute—lived significantly longer than their less fluent peers. The difference isn’t trivial. We’re talking about an almost nine-year gap in median survival time. That’s nearly a decade more to charm grandchildren, win arguments, and try out new words like “perspicacity.”

The Berlin Aging Study: Where Words Meet Years

The Berlin Aging Study, running since the late 1980s, has been the Petri dish for this linguistic longevity experiment. Thousands of older adults volunteered their brains—and their time—for repeated rounds of cognitive testing. The researchers didn’t just test IQ or memory; they zeroed in on verbal fluency as a unique marker. This isn’t just about vocabulary size; it’s about how fast and flexibly you can access words. Picture the mental gymnastics required to rattle off synonyms for “happy” or to name every fruit you can remember before the timer buzzes.

Paolo Ghisletta, the University of Geneva researcher whose name now rings out in gerontology circles, championed the notion that verbal fluency predicts survival even after accounting for other factors like education, general cognitive ability, or physical health. The findings rocked the field.

Why Words Might Keep You Alive

What makes verbal fluency such a potent predictor? Scientists aren’t entirely sure, but they have some compelling theories. The ability to access language quickly is more than a party trick; it reflects the integrity of multiple brain systems. Verbal fluency draws on memory, attention, executive function, and even social skills. In other words, keeping your word-finding gears greased could be a sign your mental engine is firing on all cylinders. There’s also the possibility that those who score high on fluency tests are more socially engaged—a factor long linked to better health and longer life.

The Limits and the Promise: Don’t Cancel Your Gym Membership Just Yet

Before you declare broccoli obsolete and stake your future on word games, researchers urge caution. Paolo Ghisletta himself warns against making individual predictions based on these findings. Verbal fluency is a strong population-level predictor, but it doesn’t mean everyone with a quick tongue will outlive the runner who struggles for words. Other factors—genes, lifestyle, and good old-fashioned luck—still matter. Experts agree: more research is needed to unravel exactly why words seem to ward off the reaper. Is it mental flexibility, neural resilience, or a life filled with meaningful conversations?

Still, the research is robust enough to shift the conversation—literally and figuratively—about what it means to age well. Next time someone scoffs at your love of wordplay, remind them you’re not just killing time; you might be buying it.
