Beyond Lifespan and Healthspan: The Case for Joyspan

Biomechanist Katy Bowman speaks with gerontologist and author Dr. Kerry Burnight about her concept of joyspan—a missing piece in how we think about aging well.

We often hear about lifespan (how long we live) and healthspan (how long we stay physically well), but what about the quality of those years? Dr. Burnight introduces joyspan as our capacity to experience a meaningful, fulfilling life as we age. In this framework, joy is not simple happiness, but a deeper sense of wellbeing that can coexist with challenge, grief, and change.

Katy and Dr. Burnight explore the Joyspan Matrix—Give, Connect, Adapt, and Grow—and how these actions enable us to thrive as we age. Rather than viewing aging as inevitable decline they discuss aging as development, the positives of aging and how to step into eldership.

Katy also speaks with our sponsor, Sohail Shariff of Movemate, creators of a unique dynamic wooden standing board that provides continuous, wave-like movement in the body while you are working at your desk or at home.

They discuss how the board supports musculoskeletal health, while also improving focus, creativity, and calm—reducing fatigue and the mental boredom and stagnation that comes from prolonged stillness. They also explore the role of play in the design, and how a serious problem—sedentary behavior—can be addressed in a way that is engaging, enjoyable, and even joyful.

Bestselling author, speaker, and a leader in the Movement movement, biomechanist Katy Bowman is changing the way we move and think about our need for movement.

What is Move Your DNA with Katy Bowman?

Movement isn’t optional—our bodies need it to thrive. Many of us struggle to get regular exercise, and even when we do, it can fall short of truly nourishing the body from head to toe. How can we move more—a lot more—when parts of us are sore, stiff, or simply forgotten in our busy lives?

Join biomechanist Katy Bowman, M.S., and biologist Dr. Jeannette Loram on Move Your DNA, where big-picture science meets practical action. Together, they explore biomechanics, kinesiology, physiology, cellular biology, and natural human movement—and translate it into simple, effective ways to wake up your trillion body parts. With humor, curiosity, and a focus on longevity, Katy and Jeannette help you move smarter, move more, and create a more natural habitat for yourself and your communities in today’s mostly sedentary world.
