Do you have a goal to lose weight? If so, you're probably thinking about how you need to exercise more. And that can certainly help. But what about the 23 hours a day you're not at the gym? How much you move during those hours — from walking to the mailbox to fidgeting at your desk — can be just as important in winning the battle of the bulge.

Here to explain the importance of what's called non-exercise activity thermogenesis, or NEAT, is Dr. James Levine, a professor, the co-director of the Mayo Clinic's Obesity Solutions Initiative, the inventor of the treadmill desk, and the author of Get Up!: Why Your Chair Is Killing You and What You Can Do About It. James explains how much more sedentary we are than we used to be and what happens to your body when, as the average American does, you spend two-thirds of your day sitting. He shares how doing the lightest kinds of physical activity, even standing more, can help you lose a significant amount of weight and improve other aspects of health, from your sleep to your mood. And we talk about how to easily incorporate more NEAT into your day.

The era of artificially intelligent large language models is upon us and isn't going away. Rather, AI tools like ChatGPT are only going to get better and better and affect more and more areas of human life.

If you haven't yet felt both amazed and unsettled by these technologies, you probably haven't explored their true capabilities.

My guest today will explain why everyone should spend at least 10 hours experimenting with these chatbots, what it means to live in an age where AI can pass the bar exam, beat humans at complex tests, and even make us question our own creative abilities, what AI might mean for the future of work and education, and how to use these new tools to enhance rather than detract from your humanity.

Ethan Mollick is a professor at the Wharton business school and the author of Co-Intelligence: Living and Working with AI. Today on the show, Ethan explains the impact of the rise of AI and why we should learn to utilize tools like ChatGPT as a collaborator — a co-worker, co-teacher, co-researcher, and coach. He offers practical insights into harnessing AI to complement your own thinking, remove tedious tasks from your workday, and amplify your productivity. We'll also explore how to craft effective prompts for large language models, maximize their potential, and thoughtfully navigate what may be the most profound technological shift of our lifetimes.

When you scroll through social media feeds today, you’ll find countless posts about “living your truth” and “being authentic.” These ideas feel so natural to us now that we rarely stop to ask where they came from or what they really mean.

The concept of identity — how we understand ourselves — has undergone a radical transformation over the centuries. What once was defined primarily by external markers like family, profession, and community has shifted dramatically toward inner feelings, desires, and psychological experiences.

Today on the show, Carl Trueman unpacks this profound change and how we got to the lens through which we view ourselves today. Carl is a professor, theologian, and the author of The Rise and Triumph of the Modern Self. Throughout our conversation, he explores the insights of three key thinkers — Charles Taylor, Philip Rieff, and Alasdair MacIntyre — who have mapped the historical and cultural shifts that have transformed our ideas of identity. We discuss how this transformation has reshaped politics, education, and religion, while considering whether we’ve lost something essential in moving from a shared understanding of human nature to an increasingly individualized conception of self.
