What if healthspan is not about adding more years to life, but protecting strength, energy, and independence as you age?
What if the real goal is not just living longer, but staying strong, capable, and energized for decades? In this episode, McCall sits down with Dr. Chris Renna, DO, founder of LifeSpan Medicine, to explore what healthspan really means and why most people start seeking answers only after symptoms have already taken hold.
Dr. Renna shares why he shifted from managing diagnoses to building true patient partnerships, and how consistent rhythms in sleep, food, movement, and perspective can change the way you feel day to day. They also discuss practical exercise targets, the role of gratitude and boundaries, and a fascinating look at emerging longevity therapies that may become far more common in the years ahead.
