AGEIST
The AGEIST podcast is where we rewrite life after 50. Hosted by David Stewart, founder of AGEIST and Super Age, we talk with extraordinary people—scientists, creatives, and thinkers—about living vibrantly in your 50s, 60s, 70s and beyond. From longevity science to emotional well-being, fitness to purpose, we explore the tools and mindsets that help us stay curious, energized, and deeply engaged with life. This isn’t about aging gracefully—it’s about living boldly.

Teemu Arina on Why Most Biohackers Are Wrong
Teemu Arina, author of Biohacker's Handbook and one of the movement’s pioneers, believes biohacking may have lost its way. In this episode, he lays out a different approach to longevity. He argues that extreme health routines often do more harm than good, and that true well-being comes from adaptability, not rigid optimization. Teemu also shares why AI-driven personal health plans could replace cookie-cutter protocols, and how we can rethink aging as a balance between discipline and enjoying life. If you’re tired of endless supplement stacks and prescriptive morning routines, this conversation offers a fresh perspective on what actually works.
