What Is Gerontology vs Geriatrics

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.
