He outlines his experimental design to evaluate the accuracy and precision of these tests, addressing important questions about what they truly measure and how reliable they are. Matt unpacks the difference between biological and chronological age, discusses the co-marketing strategies employed by these companies, and reflects on his own results to provide a critical perspective on the value of these kits. 0:00 Introduction 2:17 Experimental Design 3:03 Key Questions 5:15 Marketing Strategies of Bio-Age Companies 6:15 Biological Age vs. Chronological Age 6:49 Measuring Biological Age 8:32 Limitations of Epigenetic Clocks 13:23 Accuracy and Precision 15:49 Data Analysis 19:22 Matt’s Biological Age Results 22:53 Key Takeaways 24:50 Sanity Checks 31:58 Conclusions 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!
