    Future-Proof Your Brain with Dr. Tommy Wood

    What if the biggest lie you’ve ever been told about your health is that your brain is destined to decline? Justin Harris is joined by Dr. Tommy Wood, who currently works as an Associate Professor of Pediatrics and Neuroscience at the University of Washington, where my laboratory focuses on brain health across the lifespan — conducting research that focuses on ways to treat a range of brain injuries. This includes babies born preterm, adults who experience brain trauma, and the confluence of factors that can affect long-term cognitive function and risk of dementia. ​Dr. Tommy Wood received a Bachelor’s degree in biochemistry from the University of Cambridge, a medical degree from the University of Oxford, and a PhD in Physiology and Neuroscience from the University of Oslo. He has published dozens of scientific papers and lectured all over the world about brain health, metabolism, physical activity, and human performance. Dr. Tommy also spent more than a decade working as a performance consultant to professional athletes in multiple sports including several Olympians and world champions.  In this episode, we dive into one of the most important conversations in modern health: how to protect, strengthen, and future-proof your brain. Dr. Tommy Wood breaks down why cognitive decline is not inevitable and how your daily choices, your epigenetic inputs, play a powerful role in shaping brain health across your entire lifespan. From neuroplasticity and skill-building to sleep, social connection, and metabolic health, this episode delivers a practical, science-backed blueprint for long-term cognitive performance. ______________________________________________________ If you wish to learn more from Dr. Tommy Wood, check out the following links: Check out his book entitled "The Stimulated Mind" it is now available wherever books are sold and is available as an audiobook on Spotify PremiumCheck out his website at drtommywood.com Follow him on Instagram: @DrTommyWoodListen to his Podcast: Better Brain Fitness______________________________________________________ Keep yourself up to date on The DNA Talks Podcast!

    Sex and Longevity: Benefits of Ageless Intimacy with Susan Bratton

    What if your sex life was one of the most powerful drivers of longevity? In this episode, Dr. Tracey Steady Hardcastle is joined by intimacy expert Susan Bratton to explore the science-backed connection between sex and longevity, and why she calls it the missing pillar of health. Together, they unpack the concept of ageless intimacy - how pleasure, connection, and “orgasmic intimacy” support everything from blood flow and hormones to nervous system regulation and emotional resilience. This conversation reframes intimacy not as a luxury, but as a biological necessity for living a longer, healthier, and more vibrant life.

    Sex and Longevity: Redefining Aging With Doreen Wendt-Weir

    What if everything you believed about aging was incomplete? In this engaging and refreshingly honest episode of The DNA Talks Podcast, we welcome Doreen Wendt-Weir, author of Sex in Your Seventies and its spirited sequel, Gardening in Your Nineties. Doreen challenges cultural narratives around aging by asking bold, often humorous questions about vitality, intimacy, creativity, and identity later in life. Through her writing—and this conversation—she invites listeners to rethink what it means to grow older with curiosity, connection, and self-respect. We talk about why conversations around aging are so often avoided, how humor and honesty can open doors to deeper understanding, and why it’s never too late to redefine joy, purpose, and personal expression. Doreen’s perspective is both practical and playful, offering a counter-narrative to age-based limitations and assumptions. This episode is a celebration of longevity, lived experience, and the freedom that can come with embracing each stage of life on your own terms.

In this deeply moving and empowering episode of The DNA Talks Podcast, Dr. Tracey Steady‑Hardcastle sits down with Dr. Zelina Medina, founder of Acuvida Acupuncture, to explore the powerful intersections of autoimmune disease, trauma, nervous system regulation, functional genomics, and root‑cause healing.

Now symptom‑free for over a decade, she helps patients heal chronic illness by addressing nervous system safety, unresolved trauma, inflammation, and individualized constitutional needs. Together, Dr. Steady and Dr. Medina discuss how trauma becomes stored in the body, how genetics influence stress and inflammation responses, and why true healing requires addressing mind, body, and spirit.

    Why Keto and Intermittent Fasting Don’t Work the Same for Women’s Hormones with Dr. Lisa Olszewski

    In this deeply honest and empowering episode of The DNA Talks Podcast, Dr. Tracey Steady-Hardcastle sits down with Dr. Lisa Olszewski, chiropractor, naturopath, founder of the American Institute of Healthy Living, and host of Healthy Living Simple with Dr. Lisa. Dr. Lisa shares her personal health crisis—despite “doing everything right”—and how it reshaped her approach to nutrition, women’s hormones, ketogenic diets, intermittent fasting, and true wellness. This conversation explores why one-size-fits-all health advice fails, how women’s bodies differ biologically from men’s, and why listening to your body and your genetics matters more than following trends.

Here are the highlights of this episode: Why women cannot follow keto or fasting protocols the same way men doHow prolonged ketosis and extreme fasting can impair thyroid, adrenal, and reproductive healthWhat strategic carb cycling looks like for cycling vs. postmenopausal womenCommon intermittent fasting mistakes that stall progress or worsen symptomsHow chiropractic care impacts hormones, metabolism, and digestionWhy symptoms are warning signals—not problems to suppressHow to simplify healthy living without perfection or burnout If you wish to learn more from Dr. Lisa Olszewski, you may do so through the following channels: Podcast: Healthy Living Simple with Dr. Lisa O Website: https://healthylivingsimple.com/pages/dr-lisa-o______________________________________________________ Keep yourself up to date on The DNA Talks Podcast!
