What if one metric could predict how long — and how well — you live?

In this episode, Dr. Elie sits down with Dr. Andrew Sellars, physiologist and Co-founder of VO₂ Master, to decode one of the most powerful markers of longevity, resilience, and performance: VO₂ max.

Dr. Sellars has pioneered the world’s first truly portable, lab-grade metabolic analyzer — a technology that’s reshaping how athletes, clinicians, and wellness centers around the world measure the body’s internal performance in real time. Today, we break down why VO₂ max is far more than a fitness number — it’s a window into your mitochondrial health, metabolic flexibility, and biological age.

From elite athletes to everyday individuals, from hot Gulf climates to high-performance labs, we explore how oxygen efficiency sits at the core of human potential.
