How To Maximize Triathlon Success With Minimal Training Time

Full show notes: https://bengreenfieldlife.com/mitrix

In this episode with Tom Benson, founder and CEO of Mitrix, you'll hear why mitochondrial decline may be the actual root cause of aging rather than just a downstream symptom of it, and why most of the drugs developed so far to address it don't touch the real problem: damaged mitochondrial DNA. We discuss how Tom's company grows new, healthy mitochondria inside a bioreactor using banked stem cells, what mitochondrial transplantation actually looks like in real human cases already happening today, and the mouse study that gives this episode its name, in which severely aged mice receiving repeated mitochondrial injections were, according to the technicians running the experiment, climbing the walls of their cages by the very next day. Tom also touches on his original theory on the mitochondrial cycle of the body, how mitlets differ from naked mitochondria, and what his own MitoClock test reveals using nothing more than a urine sample.

Tom Benson is the CEO and founder of Mitrix. He is a serial entrepreneur and scientist who has founded four successful software, hardware, and science startups. He has published dozens of articles and video lectures on mitochondrial science and cellular energetics, and developed original theories on the systemic transfer and distribution of mitochondria within higher organisms and how that affects health and lifespan.

Could ONE Score Reveal How Fast You’re Aging? The Longevity Quotient & How a Former NFL Player Is Redefining The Standards of Longevity Medicine, With Jimmy St. Louis

Full show notes: https://bengreenfieldlife.com/bretthurt

In this episode with Brett Hurt, serial tech entrepreneur and author of Love Conquers Fear, you'll hear how he went from coding obsessively at seven to building one of the early internet's most popular games, surviving the dot-com bust, orchestrating two major exits, data.world to ServiceNow and Bazaarvoice's billion-dollar IPO, and experiencing a psychedelic awakening at 50 that redirected his entire life.

You will also hear his vision for what an Age of Abundance looks like in practice, from solar energy and robotics to brain-computer interfaces and the role AI might play in solving problems like clean water, food security, and healthcare access in places like Chad, and why Brett believes the single most important variable in whether AI helps or hurts humanity is whether the people building it are operating from love or from fear.

Brett Hurt is a tech entrepreneur and investor. He co-founded and led data.world, acquired by ServiceNow in July 2025, and previously co-founded Bazaarvoice and Coremetrics, acquired by IBM. Through his Love Conquers Fear holding company and podcast, he explores how AI and emerging technologies can either amplify fear or help create broad-based human flourishing.

Pick up a copy of Love Conquers Fear to discover how Brett crosses the streams of ancient wisdom and cutting-edge technology, rewiring humanity's relationship with AI, quantum computing, and emerging tech to move us from scarcity to abundance.
