Dr. Brian Kennedy, PhD: The 5 Factors That Influence How Long You Live
Brian Kennedy is one of the world’s leading researchers studying the biology of aging.
In this conversation, we break down what longevity science actually shows about extending healthy lifespan and the everyday habits that appear to influence how we age.
Dr. Brian shares insights from decades of aging research, explaining how scientists study longevity, how interventions like rapamycin and biological age testing are evaluated, and how lifestyle factors such as exercise, nutrition, fasting, and sleep continue to shape the foundation of long-term health.
