100 Not Out

Today we tackle one of the hottest trends in health and longevity: infrared saunas. With social media awash in commentary — from skeptics to evangelists - and high-profile figures like Bryan Johnson dismissing their benefits, it can be difficult to separate fact from fiction.
 
To unravel the science, history, and practicalities behind saunas, we welcome Sebastian Mierau, founder of Clearlight Saunas International and a longtime expert in sauna technology and wellness. 
Whilst Sebastian is a friend of Marcus, we don’t shy away from asking the hard questions that listeners want the answers to. 
 
We explore the origins of both traditional and infrared saunas, discuss the potential health benefits and risks (including electromagnetic fields), and answer whether infrared saunas really stack up when it comes to improving longevity, recovery, and relaxation. 
Whether you’re a sauna skeptic or superfan, this episode is packed with accessible science, practical advice, and some surprising perspectives on what it really takes to live a long, healthy, and enjoyable life.

Fresh off the City to Surf run—despite a pesky calf injury— Damo shares his lessons from pushing physical limits in his 50s, as we challenge the narrative that we should slow down as we age. 
On this ep we explore the difference between “old man / woman injuries” and the badges of honour that come from being actively engaged in life. 
We touch on inspiring stories of longevity, from 90-year-old athletes to the wisdom of Blue Zones, and reflect on the importance of staying competitive—no matter your age. 
Plus, get a peek into our upcoming travels to Sardinia and Ikaria, where we’ll continue searching for the secrets of exceptional longevity. If you’re a crazy one and want to book a last minute spot - we may have one remaining. Details at www.100notout.com

Today we step into the ring for a "Battle Royale" of philosophies: Blue Zones versus Bryan Johnson. 
The growing divide between biohacking and the time-tested, lifestyle-based secrets of the world’s longest-living populations.
From stories of 108-year-old golfers to the role of philosophy, science, diet, and social connection in health, we examine what truly lies at the heart of longevity. Is it lab results, supplements, and routine blood tests? Or is it wine with friends, daily movement, and the kind of social connection you can’t measure with data? Or perhaps a bit of both?
Get ready to question the role of science as the new religion, the nuances in nutrition and lifestyle advice, and how we each can navigate our own path to a long, vibrant life.

Today we unpack the science, challenge long-held beliefs, and share what we think it means for the narrative of longevity.

Today we’re talking about breaking the so-called "rules" of sleep and discovering true fulfillment through social connection, laughter, and a more fluid lifestyle. 
Drawing insights from almost a decade of travelling to the Blue Zones of Ikaria and Sardinia, we explore why happiness and longevity often come from embracing flexibility, meaningful relationships, and letting go of rigid routines — even if it means sacrificing a perfect sleep score.

In this lively chat we dive into the importance of physical vitality, community, and starting exactly where you are on your health and longevity journey - no matter your age or current ability. 
 
From celebrating personal milestones in strength training to powerful lessons learned on the golf course with friends, we highlight how combining movement with social connection amplifies the experience of growing older with purpose and zest. 
 
We celebrate listener wins, insights from longevity role models, and reflect on our own approaches—biases and all—toward living a fulfilling, vital life. Whether you’re just starting out or looking for renewed motivation, this episode will remind you: it’s never too late to start; and always too early to stop.

Embracing Spontaneity: How Aging Attitudes and Travel Plans Are Changing in 2026
 
Today’s conversation dives into the ever-evolving landscape of planning. 
On the back of the announcement that we are going back to Europe in September to run two Longevity Experiences (click here for Ikaria and here for Sardinia), we discuss how this never would have happened back in 2019. 
Long haul travel and spontaneity have rarely gone hand in hand. And global shifts—like the aftermath of COVID-19 and changes in consumer sentiment — are transforming not only the way we travel but the way we live our lives.
Gone are the days of 10 year visions and planning long haul trips 12 months in advance. We don’t know what’s happening in 6 months let alone 12, and as a result, we are determined to “live each day as if it’s our last” perhaps today more than ever.
