Building Joyspan: How Purpose and Connection Extend Healthspan with Dr. Kerry Burnight

Saison 1 · Épisode 98

mercredi 5 novembre 2025 • Durée 57:26

In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Kerry Burnight, Gerontologist, Chief Gerontologist, New York Times best-selling author, and researcher. They explore what it truly means to age well, focusing less on resisting the passage of time and more on embracing vitality, curiosity, and joy throughout life’s second half.

Dr. Burnight explains why the common “decline” mindset around aging misses the full story. She shares research showing that meaningful growth, strong social connections, adaptability, and a sense of giving can shape both how long and how well we live. Dr. Burnight offers practical examples for building these habits, from maintaining friendships across generations to finding purpose in everyday acts.

Throughout the conversation, Dr. Burnight urges listeners to rethink their beliefs about aging and to prepare for later life with intention. She shows that nurturing joy and purpose is just as important as physical health, and that everyone can take steps to build a more satisfying, resilient, and joyful future.

Why Sleep Trumps Exercise for Long-Term Health with Dr. Florence Comite

Saison 1 · Épisode 97

mercredi 22 octobre 2025 • Durée 01:03:01

In this episode of Longevity by Design, host Gil Blander sits down with Florence Comite, MD, physician-scientist and founder of the Comite Center for Precision Medicine & Healthy Longevity. They explore why a one-size-fits-all approach to longevity falls short and how personalized data, from biomarkers to genetics, can spot early signs of disease before symptoms appear.

Florence explains her “Nof1” method, which uses deep testing, wearables, and personal history to craft precise health plans. She highlights how sleep, more than exercise or diet, shapes long-term health but remains hard for most people to optimize. Using real-world examples, Florence shows why tracking markers like insulin and hormones matter, and why most people need support to turn health knowledge into action.

The conversation covers the limits of standard medical care, the value of knowing your family history, and how even the best routines must adapt over time. Florence urges listeners to get curious about their own data and take steps—however small—toward better health.
