“Beliefs Are Tools, Not Truths”

The Greek philosopher Epicurus made a rather bold claim over two thousand years ago. The key to life, he said, is simple: pursue pleasure and avoid pain. Around this maxim he developed a school of philosophy, Epicureanism, which promised its adherents that if they took care of their basic needs, surrounded themselves with trustworthy friends, and developed a basic understanding of science, they would be happy. But is it really that simple? Can the advice of someone born 2,363 years ago still hold true? To answer these questions, we turned to Emily Austin, professor of philosophy at Wake Forest University and author of the delightful book Living for Pleasure: An Epicurean Guide to Life.

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. 🔗 LINKS AND MENTIONS: Check out our playlist of health-related episode on Spotify The Next Big Idea Club — Save 20% on any membership when you use code PODCAST at nextbigideaclub.com Granola — If meetings are eating up your day, Granola is a no-brainer.

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. 🔗 SPONSORED BY: Granola — If meetings are eating up your day, Granola is a no-brainer. You can try it totally free for three months.

In celebration of Apple's 50th birthday, we're probing the company's past and peering into its future with David Pogue — former New York Times tech columnist, current CBS Sunday Morning correspondent, and author of the recent New York Times bestseller Apple: The First 50 Years. We begin by looking backward, exploring the improbable story of the hippie pranksters who built the world's first trillion-dollar company. But we're not just here for the history. We also look ahead, asking: What cool new tech are they cooking up in Cupertino? Why has Apple been so slow on AI, and does the company have a plan to catch up?
