Overview
For much of our lives, performance is measured in speed, strength, and output. As we get older, the equation changes.
On this episode of The Dr. Hyman Show, I sit down with Sir David Beckham and Dr. Dawn Mussallem to explore what elite sport, stage IV cancer, and heart transplantation can teach us about prevention—and what it really takes to sustain health over time.
Together, we explore:
-
Why your health trajectory is more changeable than you’ve been taught—especially after 40
-
How sleep, stress, and metabolic health quietly shape your long-term disease risk
-
Which daily habits give you the biggest return on investment over decades
- How to build resilience now so your body supports you later
The real measure of health isn’t what you can achieve in your 20s or 30s. It’s the resilience you build so your body supports you for decades to come.

You were the first one to run a marathon within a year of having a heart transplant.
