The BioAge Index™
Welcome to The BioAge Index - the show for business owners, executives and high performers who want more energy, less drag and a younger biological trajectory.
I’m Grant Hutchby, creator of REVO and the Turnback Time system.
Our mission is simple:
Reclaim as many years of optimal life as possible, in as many people as possible, as accurately as possible.
Chronological age does not tell the full story. Your sleep, energy, stress, training, recovery and consistency are already creating a direction of travel.
The BioAge Index™ helps you understand that trajectory, find your biggest drag and track improvement over time.
It is directional, not a clinical diagnosis.
Subscribe for videos on biological age, performance, recovery, longevity science and the Turnback Time system.

Set your baseline. Find your drag. Track your trajectory. Live better, longer.

How to Reverse Biological Age at the Cellular Level
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Most people think biological age is just one number.
It isn't.
In this conversation, I'm joined by Dr Sandra Kaufmann, physician, cellular biologist, longevity expert and creator of the Kaufmann Protocol, to explore what biological age really means and why measuring it accurately is far more complex than most people realise.
We discuss why healthspan matters more than lifespan, why focusing on a single biomarker can be misleading, and how true longevity comes from understanding the body as an interconnected system rather than chasing individual health trends.
Inside this episode, we cover:
• The difference between lifespan and healthspan
• Why biological age is more than a single test result
• The limitations of telomeres, epigenetics and NAD testing
• Why researchers often become too focused on one area of ageing
• The seven cellular mechanisms that drive ageing
• How mitochondria, inflammation and DNA repair influence longevity
• The role of sirtuins, mTOR and circadian rhythms
• How the Kaufmann Protocol approaches healthy ageing
• The science behind supplements including NMN, pterostilbene, astaxanthin, curcumin and carnosine
• Why sleep, stress and recovery remain the foundation before advanced interventions
• The future of longevity through peptides, exosomes and biologics
If you're interested in biological age, longevity science and optimising your health with evidence-based strategies, this episode provides a practical framework from one of the world's leading experts in cellular ageing.
