    You Can Grow Your Brain. Here’s How.

    05/11/2026 | 1h 20 mins.
    In the last 20 years, there has been a dramatic change in our understanding of neuroplasticity — the brain’s capacity to grow new neurons. In the last five years, we’ve learned that your hippocampus, the part of your brain responsible for learning and memory, can get bigger at any age. Majid Fotuhi, who teaches at Johns Hopkins, has been at the forefront of a new body of research demonstrating that lifestyle changes — tweaks to the way you exercise and eat, adjustments to your sleep and mindset — can improve your brain health no matter how old you are. They can even reverse early-stage Alzheimer’s. His new book is The Invincible Brain, and the message is clear: with the right lifestyle and mindset changes, you can grow a bigger brain.

    You're in the Hospitality Business (Whether You Know It or Not)

    05/04/2026 | 1h 3 mins.
    For the last three years, Will Guidara has been on the road talking about unreasonable hospitality. He's met financiers and prison wardens, educators and athletes, Fortune 500 executives and small business owners. They kept asking the same question: "I get how this works in a restaurant, but how do I apply it in my business?" So Will wrote them an answer. It's called Unreasonable Hospitality: The Field Guide.

    We're Still Thinking About This Conversation with Will Guidara

    04/30/2026 | 1h 2 mins.
    In September 2023, Will Guidara told us the story of how he used two words to turn a middling brasserie into the best restaurant in the world. Those two words? Unreasonable hospitality.

    We're running that episode again today because, well, it's one of our all-time favorites. And because Will is coming back on the show on Monday to discuss his brand-new book, Unreasonable Hospitality: The Field Guide. Consider this the appetizer.
