Summary
Your brain is aging faster than it should, and most of the decline is self-inflicted. Neuroscientist Dr. Tommy Wood reveals the exact mechanisms driving cognitive decay, and the biohacking strategies backed by hard science that can stop it, reverse it, and future-proof your brain at any age.

Host Dave Asprey sits down with Dr. Tommy Wood, one of the most credentialed minds working at the intersection of brain optimization, human performance, and longevity. Dr. Wood holds a medical degree from the University of Oxford, a PhD in physiology and neuroscience from the University of Oslo, and serves as Associate Professor of Pediatrics and Neuroscience at the University of Washington School of Medicine. He has published over 100 scientific papers, consulted with Olympians and world champions across more than a dozen sports, and worked directly with Formula 1 drivers to sustain elite focus and reaction time at 200 miles per hour. His forthcoming book, The Stimulated Mind: Future-Proof Your Brain from Dementia and Stay Sharp at Any Age, is the culmination of decades of research and real-world application.
Together, Dave and Dr. Wood dismantle the myth that cognitive decline is inevitable, exposing how societal expectations become self-fulfilling prophecies and how the tools of biohacking, including sleep optimization, neuroplasticity training, nootropics, supplements, and strategic exercise, can dramatically shift your brain's long-term trajectory. They dig into the 3S Model of brain health (Stimulus, Supply, Support), the Yerkes-Dodson arousal curve and what it means for focus and flow states, and the surprising truth about AI, boredom, and what actually happens to your brain when you let ChatGPT do your thinking for you.
This episode is essential listening for anyone serious about anti-aging, brain optimization, functional medicine, metabolism, human performance, and getting smarter without working harder.
You'll Learn:
- Why cognitive decline is largely a self-fulfilling prophecy driven by expectation, not biology
- How the 3S Model (Stimulus, Supply, Support) determines your brain's long-term health and resilience
- What Formula 1 drivers teach us about arousal, flow states, and peak cognitive performance
- Why high-intensity interval training produces dramatically greater neuroplasticity benefits than Zone 2 cardio alone
- How creatine, nicotine, nootropics, and other supplements actually affect the aging brain
- The real data on alcohol, dementia risk, and what "occasional drinking" actually means scientifically
- How to use AI tools like ChatGPT in a way that builds brain function instead of destroying it
- Why boredom is a neurological necessity and how chronic low-level stimulation is quietly eroding your cognition
- What mitochondria and lactate signaling have to do with BDNF and long-term memory
- How resistance training, coordinative movement, and blood flow restriction each deliver separate and distinct cognitive benefits

| 0:00.0 | He helped to popularize the idea of retirement, essentially by telling people that once you hit 60, |
| 0:05.0 | you're essentially useless and you need to be put out to pasture. |
| 0:08.0 | And we have then internalized that as a society and we expect significant loss of function. |
| 0:13.0 | If we think that we're going to lose function with age, we stop doing the things that prevent the processes of aging, |
| 0:19.0 | and therefore it becomes a self-fulfilling |
| 0:20.9 | prophecy. |
| 0:21.9 | We have this overarching idea of trying to build what I call headroom. |
| 0:27.2 | So headroom is the maximum capacity that you have available to you because when things |
| 0:32.9 | come in that inhibit or diminish performance, sleep deprivation, acute stress, illness, right? |
| 0:39.1 | You want more capacity available to you so you can maintain function. |
| 0:42.0 | How this then works, I have this model that I call the 3S model of brain health. |
| 0:47.1 | And the 3S is a stimulus supply and support. |
| 0:50.5 | This is just ground zero for the kind of knowledge for having the kind of brain that you want |
| 0:54.5 | and the kind of brain you want right now, even if you're 19 years old or if you're 90 years old. |
| 1:00.9 | You're listening to the Human Upgrade with Dave Asprey. |
| 1:08.1 | How many nights have you stared at the ceiling, counting the hours until morning? |
| 1:12.6 | Maybe you try to sleep supplement, but it knocked you out and left you groggy, like you traded one problem for another. |
| 1:19.6 | Poor sleep doesn't just make you tired. |
| 1:21.6 | It kills your performance, slows your brain down, and speeds up aging. |
| 1:25.6 | Kill Switch from Switch supplements solves that problem. |
| 1:29.6 | It works with your biology instead of against it. It contains five gut-friendly, extensively researched |
