For today’s special bonus episode, David welcomes Tavi Castro to the show to explore the bold decisions and mindset shifts that have defined Tavi’s journey—from walking away from the toxic elements of fitness culture to reinventing himself through the meditative power of freediving. Tavi recounts how a devastating injury led him into the water, sparking a new passion that reignited his purpose. His viral video—where he appears to leap through an underwater cloud—garnered hundreds of millions of views, but it wasn’t fame he was chasing. Instead Tavi speaks on the importance of authenticity in content creation, how he uses visual art to share messages of peace, and why he rejected sponsorships to protect his creative and spiritual integrity. David and Tavi also discuss his intermittent fasting approach, how he eats and trains to sustain elite performance, and the introspective practices that drive him. Now, with a screenplay in development that explores humanity’s search for meaning in an AI-driven world, Tavi is channeling all of his life’s experiences—fitness, music, diving, and resilience—into one cinematic project. This special conversation is an invitation to redefine success, embrace discomfort, and live with bold intentionality—don’t miss it!

Dr. Will Cole sits down with David on today’s episode of The David Nurse Show to unpack one of the most pressing issues facing America: our broken approach to healthcare and nutrition. Despite spending more on healthcare than any other industrialized nation, the U.S. faces skyrocketing chronic disease and declining life expectancy. Will doesn’t just point out the problems—he presents solutions through his work with the “Maha” movement (Make America Healthy Again), which is aiming to democratize access to functional medicine and break the grip of the pharmaceutical and processed food industries. Together Will and David expose the deep-rooted issues: food subsidies that promote disease, misinformation in media, and political agendas that distort the truth. They also tackle the cultural contradictions—how toxic diet culture has swung to glorify obesity under the guise of body positivity, and why self-respect should be the foundation of nutritional choices. The conversation balances big-picture activism with personal responsibility, offering both inspiration and actionable guidance.

Ever struggle with refocusing during the day or recharging at night? Meet Muse, the newest innovation in meditation technology. Use my link for 20% off your purchase today: http://choosemuse.com/NURSE The flow state: that ever-elusive place where anything comes naturally—actions follow thoughts and everything works together in perfect harmony. How do we achieve that flow state to perform at our highest levels, or is that even possible? On today’s episode of The Dr. & The Nurse David sits down with acclaimed neuroscientist and the creator of Muse, Ariel Garten, to outline exactly how to attain that state of flow through optimized sleep, meditation, and visualization. David and Ariel begin their conversation by looking at some of the ways we can achieve flow state, from metavisualization—a combination of meditation and visualization—to stimulating pressure so we can perform better when the pressure is actually real. They then get into how optimizing sleep can help us perform to the best of our ability no matter what we’re trying to achieve. Ariel points to Muse—a tool she helped create—that acts as a data tracker for your brain and can also be used as a meditation tool to help you fall asleep, and stay asleep. The two wrap up their conversation by discussing how to de-regulate and up-regulate your brain for optimal performance.

We’re starting off 2025 with a bang, looking at how to become unkillable according to human performance scientist Dr. Andy Galpin. Is it possible for a person to become virtually invincible? And how does that translate to the way we think and react to high-stress situations? David sits down with Andy to find out exactly that on this first episode of The Dr. & The Nurse for 2025. David starts out his discussion with Andy by breaking down exactly what it looks like to become unkillable: the physiological aspects, the physical training, and the psychological expertise. The two then do a deep dive into why resilience is so important to this idea of being unkillable, and how to build resilience into your everyday practices. Finally, Andy hits on the importance of sleep and why this simple tool is so essential on the path towards becoming unkillable. Dr. Daniel Amen joins David for the second part of this conversation, looking at how to build a bulletproof, unkillable brain. Dr. Amen takes a look at the practices of high-performance athletes and the ways they manage their minds to point out some of the commonalities of individuals with this unkillable mindset.

On today’s episode of The Dr. & The Nurse, Gabby sits down with David to talk about how each of us can use the practices she’s employed to create our dream lives. David begins the conversation by asking Gabby how she maintained her focus on what mattered most as her career change and priorities shifted—first from athlete/spokeswoman to now business owner/mother/wife. Gabby walks us through some of her daily focus practices: how she schedules her day to capitalize on her best windows of focus, balancing scatterfocus and hyperfocus, and when (and how!) to tap into a flow state of focus. Their conversation wraps up with Gabby sharing some of her best advice for building that life of intentional focus.  Dr. Daniel Amen joins David for the second half of this episode—taking a look at what’s going on in Gabby’s brain when she taps into that intensely focused state.

Welcome back to another super practical episode of The Dr. & The Nurse! This week on the show David welcomes Grayson Boucher, aka “The Professor,” professional street basketball player turned content creator best known for his creative take on the game. During their conversation David and The Professor talk skill mastery: how to attain that level of achievement in any area, if it really takes 10,000 hours to truly master something, and the relationship between creativity and execution. This first part of the episode wraps up with The Professor outlining how he translated skill mastery of basketball into skill mastery in the content creation world. Dr. Daniel Amen joins David for pt. 2, looking at what’s actually going on in The Professor’s brain when he talks about creatively mastering a new basketball move or video edit. Though Dr. Amen believes everyone is inherently creative, he cautions listeners with employing creativity too early when attempting to master a new skill—instead encouraging them to perform slowly and deliberately before adding in their own dose of creativity.

We live in an age of digital distraction—from social media and Google to information overload and the constant presence of our phones, it’s getting harder and harder to live a life of slow productivity. Computer scientist and bestselling author, Cal Newport, wants to help change all that. On today’s episode of The Dr. & The Nurse, David sits down with Cal to discuss how to lead a less distracted life in the hopes of achieving a state of “deep work.” David doesn’t waste a minute of this conversation, asking Cal his take on how technology is affecting this generation and the generations to come, and if there’s an antidote to the level of digital distraction we’ve grown used to as a society. Together Cal and David discuss the myth of multitasking for productivity, outline how to eliminate distractions in order to achieve that deep state of work, and Cal shares some of his favorite tools for living an unhurried life. Dr. Daniel Amen joins David for the second part of this episode, looking at what’s going on in our brains when we continue to live digitally distracted. The two take a look at the recent changes countries like Australia have made to limit social media use in those under 16 years-old, plus outline ways to swap low-dopamine activities (like social media and video games) for high-dopamine options that will leave you feeling filled up rather than depleted.
