“Longevity is not just about the big number, it’s really about your health span and the quality of your life along the way.”

The 5-Step System That Will Reset Your Body & Help You Live Longer

My life-changing annual event, The Summit of Greatness, is happening September 12 & 13, 2025. Get your ticket today!

Dr. William Li blows my mind with what he discovered about people living past 100. They have four specific gut bacteria that most of us are missing. Here’s what hit me hardest: 70% of your immune system lives in your gut, and there’s now evidence that dementia might actually start there, not in the brain. We spend two hours diving deep into how your gut bacteria literally text messages your brain (there’s one that triggers the same hormone as a passionate kiss!), and Dr. Li revealed the simple changes that can transform your health without expensive biohacking. This conversation changed how I think about longevity. It’s not about chasing a number, it’s about nurturing the 39 trillion bacteria that determine whether you thrive or just survive.

And now let’s jump into episode 1811 of The School of Greatness!

Some Questions I Ask:

  • “Why do you think people care so much about being immortal or living for as long as they can?”
  • “How much of what we eat impacts our brain – either giving us clarity and focus versus cloudiness?”
  • “What happens to the gut, the bacteria in your body and immune system when you eat ultra processed foods versus whole foods?”
  • “If someone has neglected their health for many years and they’re living with excess weight, what would you prescribe as a 90-day game plan to reset?”
  • “How much do our thoughts and our mindset impact our gut and our overall health?”
  • “How much of a block are people creating in the flow of health when they’re smoking or vaping every day?”
  • “What are the new things that you’re observing that most people aren’t noticing about people that live well into their hundreds?”
  • “Does that mean there are four bacteria in people that live beyond 100 that people under 100 don’t have?”

In this episode, you will learn:

  • Discover the four specific gut bacteria found in super-centenarians that you can actually cultivate through simple food choices – no expensive supplements required
  • Transform your understanding of dementia and brain health by learning how gum disease and gut bacteria might be the hidden triggers we’ve been missing
  • Break through the confusion about processed foods by understanding exactly what happens when they enter your body versus whole foods (Dr. Li’s symphony analogy is unforgettable)
  • Unlock your body’s natural healing systems with Dr. Li’s practical 5-step reset plan that costs nothing but can change everything
  • Revolutionize your sleep by understanding the glymphatic system – your brain’s hidden sewer system that only opens when you get deep sleep
  • Plus much more…
