The Optispan Podcast with Matt Kaeberlein

Subscribe to our channel: https://www.youtube.com/@optispan In this episode with our guest Dr. Thomas Seager, we delve into the transformative power of cold plunge therapy and its profound effects on resilience and longevity. We explore real-life case studies, including lessons learned from infrastructure failures like Hurricane Katrina and the Oroville Dam crisis. Discover how psychological resilience shapes our responses to stress, the importance of hormesis in health, and the role of brown fat in metabolism. We also discuss the impact of fasting, caloric restriction, and the relationship between mitochondrial health and aging. 00:00 - Introduction to Cold Plunge and Resilience 03:33 - Types of Stress & Responses 14:18 - Mitochondrial Health, Caloric Restriction & Metabolism 23:05 - Cold Therapy and Brown Fat 54:10 - Conclusions & Final Thoughts Producers: Tara Mei, Nicholas Arapis Video Editor: Jacob Keliikoa DISCLAIMER: The information provided on the Optispan podcast is intended solely for general educational purposes and is not meant to be, nor should it be construed as, personalized medical advice.

I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it. On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!

Matt dives into the intriguing world of biological age testing by comparing results from different epigenetic kits. He explores the differences between biological and chronological age, revealing that the tests often provide inconsistent results. With skepticism at the forefront, he questions the accuracy and reliability of these popular kits. Marketing strategies of the companies are dissected, highlighting potential conflicts of interest. Ultimately, he offers a critical perspective on the true value of biological age testing in understanding health.

Drawing from his background in environmental engineering and public health, Thomas discusses the pressing health issues affecting longevity in Americans and a potential shift from a reactive healthcare model to one that emphasizes proactive health management. Together, Matt and Thomas examine the complexities of early disease detection, the promise and limitations of AI in analyzing biomarkers, and the difficulties of separating reliable information from misinformation in today’s digital landscape. Thomas shares his personal experiences with biomarkers and resilience practices, such as cold exposure therapy, while he and Matt discuss the biases in medical research and differing approaches to health. Thomas is an Associate Professor at ASU in the School of Sustainable Engineering and the Built Environment. His research focuses on sustainable engineering and resilience, addressing topics such as infrastructure resilience, sustainable energy systems, and environmental ethics. He is also the co-founder of Morozko Forge, a company that promotes cold immersion therapy as a means of supporting metabolic resilience. 0:00 Introduction 2:34 Environmental engineering and public health 6:29 Major health crises affecting longevity 10:30 Public’s evolving views on modern healthcare 11:45 “Repair Shop” mentality in medicine 12:59 Two key questions: Advancing proactive medicine and filtering out misinformation 16:00 Understanding biomarkers 18:35 Weighing the risks and rewards of early detection 25:10 Japan’s 1991 Cold Stimulation Study 31:10 Bias and skepticism in medical research—different perspectives 39:12 The positivist approach to hypothesis-driven work Producers: Tara Mei, Nicholas Arapis Video Editor: Jacob Keliikoa DISCLAIMER: The information provided on the Optispan podcast is intended solely for general educational purposes and is not meant to be, nor should it be construed as, personalized medical advice.

Subscribe to our channel: https://www.youtube.com/@optispan Grief: one of the most profound emotions humanity shares; a universal experience that transcends time, culture, and place; a phenomenon as ancient as human existence. Grief is as intrinsic to the human experience as joy or hope, and no one escapes it—to grieve is to be human. In this episode, Matt and Nick discuss their recent personal experiences with grief and loss. Matt lost his German Shepherd Dobby to degenerative myelopathy, while Nick's father succumbed to health issues precipitated by heavy alcohol use. Together they explore how grief affects mental and physical health, including how it affects the four Pillars of Healthspan—Eat, Sleep, Move, and Connect—as well as the hallmarks of aging. They also discuss the tricky emotions that can accompany grief, the different ways people react to change, and the unanticipated positives of negative experiences.

In this engaging discussion, naturopathic doctor Kim Celmer sheds light on her unique approach to patient care. She clarifies the distinctions between food allergies and sensitivities, pointing out their implications for gut health. Kim also delves into remedies for common digestive issues like heartburn, emphasizing the risks of overusing antacids. Additionally, she shares insights on nutritional deficiencies, particularly vitamin D and iron, and how they affect overall health. This conversation is a treasure trove of natural health tips!

The discussion dives into the evolution of healthcare, highlighting how Medicine 2.0 focuses on reactive care yet overlooks healthspan. It contrasts this with the vision for Medicine 4.0, which promotes proactive, personalized health strategies. The podcast urges a shift in focus from merely living longer to enhancing vitality and quality of life. Additionally, Matt hints at the future with Medicine 5.0, promising innovation through geroscience and AI to tackle the biology of aging and improve health outcomes.

Subscribe to our channel: https://www.youtube.com/@optispan How much longer might humans live? This question has fascinated scientists, philosophers, and dreamers for centuries. The average human lifespan has already increased dramatically over the past hundred years thanks to advances in medicine, public health, and technology, and the prospect of radically extending human life remains one of humanity’s most compelling frontiers. A recent paper published in the scientific journal Nature Aging argues that radical life extension is unlikely to happen in the 21st century. The paper has sparked fascinating conversation in the longevity industry around topics such as realistic deliverables for the field, the predictive value of past technological trajectories, the reasons behind lifespan decreases in the western world, incremental versus bold research goals, and where we should go from here. Matt and Nick discuss the paper and provide their own take on the prospect of radical life extension and what we can realistically expect to see in the coming decades.
