Full Show Notes: bengreenfieldlife.com/cook2026

 In this episode, I welcome regenerative medicine expert Dr Matthew Cook to explore what's new and exciting in regenerative medicine. You'll hear firsthand about groundbreaking stem cell treatments, the best peptide stacks, and how exosomes are shaping the future of health and longevity. Whether you're curious about the science behind anti-aging, optimizing recovery, or what's next for wearable tech and AI in healthcare, this conversation delivers practical insights and actionable takeaways.

Dr. Cook graduated from the University of Washington School of Medicine, completed his residency in anesthesiology at the University of California San Francisco (UCSF), and completed fellowships in Anti-Aging, Metabolic and Functional Medicine, and Peptide Therapy with the American Academy of Anti-Aging Medicine.

After a decade focused on functional medicine (with 14 years prior working as an anesthesiologist), Dr. Cook's specialty is addressing the most challenging conditions. His proprietary multimodal approach regenerates, repairs, and restores health on a cellular level, dealing with root causes rather than masking symptoms.

Welcome to RAW—my unfiltered solo podcast, hosted on LIFE Network (which is completely free to join here—you can listen to every RAW episode plus a full library of health and wellness podcasts, including Boundless Life). RAW is where you get the real, behind-the-scenes version of my life: the biohacking experiments I’m running on myself, the protocols I’m creating, the tools and tech I’m stress-testing before anyone hears about them, the ideas in physiology, performance, and longevity I’m diving into, the beliefs I’m questioning, the routines I’m refining, and the unconventional stuff I’m actually doing day to day.

In this episode, I open up about one of the most powerful anchors in my family's life—our daily bookends. These are the routines my family and I use to start and end each day with intention, connection, and purpose. I walk you through our morning huddle, where we check in, talk schedules, share a devotional, and pray together using the ACTS method. And at night, we gather for a family dinner complete with song, prayer, game time, and meaningful conversation—no matter how busy our days have been. I share not just the how, but the why behind these practices, emphasizing their impact on raising well-rounded kids, building family legacy, and nurturing relationships. Whether you've got a spouse, roommates, or a big family, I'm giving you a roadmap you can adapt to create magic and togetherness in your own home. Hope it inspires you to try something new—thanks for joining me on this RAW episode!

Morning and Evening Bookends: Building Strong Family Rituals for Connection and Growth - LIFE Network: RAW Podcast #4

*In this episode, you'll discover a three-step framework for exposing the unconscious patterns quietly running your life and learn exactly how to flip each one.*

## Episode Summary

In this episode, I introduce a very helpful life transformation framework called “Identity Inversion.” It's a simple exercise I designed (based on my own self-experimentation!) for identifying unconscious patterns, habits, and identity traps that are keeping you from becoming the best version of your broken self. Using two relatable examples (a man addicted to the gym for self-worth and a woman addicted to productivity for approval), I’ll walk you through a three-step process: describe the pattern in a paragraph, name its redemptive opposite in a sentence, then distill it into a single word that becomes the key to redrawing your identity. Next week, so you can get a really concrete idea of what this looks like, I’ll share my own 10 identity inversions.

## Question of the Day 🗣️

What's one identity pattern you've been running on autopilot, and if you flipped it, what single word would describe who you'd become?

## Key Takeaways
How you live your days is how you live your life, and chances are, you are stuck in a hypnotic trance of habits shaped by old desires, environments, and upbringing that quietly became your identity.
The Etch-A-Sketch metaphor: your daily habits get drawn together to form your identity, and sometimes you need to shake the board and redraw it.
Identity Inversion is a 3-step exercise: describe an identity pattern in one paragraph, name its redemptive opposite in one sentence, then distill that into one single word.
Example: A man whose identity is wrapped up in gym performance discovers his inversion word is "confidence," meaning being secure regardless of how his body looks.
This isn't self-worship or moral polish, because growth disconnected from loving God and loving others always stalls out or turns inward.
