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.
