What Makes Life Worth Extending?
What does it really mean to live longer—and live better?
In this episode of the Living to 100 Club, Dr. Joe Casciani speaks with Leslie Kenny, Member of the Board of Directors, Oxford Longevity Project, about the psychological, biological, and lifestyle factors shaping longevity around the world.
Leslie shares surprising findings from a global longevity study involving 25 countries, including striking attitudes toward aging among younger generations. Together, Joe and Leslie explore how purpose, mindset, social connection, and healthy lifestyle habits can influence not only lifespan, but quality of life along the way.
The conversation also examines ageism, reinvention later in life, anti-inflammatory approaches to health, and the idea that aging can become a new chapter filled with growth, curiosity, and renewed meaning.
Leslie also discusses her own personal health journey and why she believes individuals should remain hopeful, proactive, and engaged in shaping their future health and well-being.
