Why So Many People Feel Empty & The Truth About What Humans Should Eat

Heat can make people do some strange things. It can change your mood, cloud your judgment, and even affect the way you treat other people. Scientists have discovered that hot weather has a surprisingly powerful influence on the human mind—and the effects show up in places you would never expect. Listen as I explain what's really going on and why it's important to know. https://www.apa.org/monitor/2024/06/heat-affects-mental-health More people today say they feel their lives lack meaning and purpose than at any point in recent decades. Why? Has modern life quietly stripped away something essential—or are we simply searching for fulfillment in all the wrong places? And if purpose really is the key to a happier life, where does it actually come from? There is no better person to explore these questions with than my guest Arthur Brooks. He is a professor at Harvard Business School, one of the world's leading experts on happiness and human flourishing, a nationally syndicated columnist, CBS News contributor, and co-author with Oprah Winfrey of the bestselling book Build the Life You Want. His latest book is The Meaning of Your Life: Finding Purpose in an Age of Emptiness (https://amzn.to/4yUyVTp). If you've ever wondered what truly gives life meaning—and why so many people struggle to find it—you'll find this conversation fascinating. Every few months it seems we're told to stop eating one food and start eating another. Fat is bad—until it isn't. Carbs are the problem—unless they're not. With so much conflicting advice, it's no wonder so many people have no idea what a healthy diet actually looks like. According to Daniel Lieberman, much of what we've been taught about food is based on myths, misconceptions, and oversimplified thinking. Lieberman is Chair of the Department of Human Evolutionary Biology at Harvard University and author of Fed Up: A Hungry Person's Guide to the Story and Science of Food and Diets (https://amzn.to/4btal2d). He explains what the science really says, why nutrition has become so confusing, and how understanding our evolutionary past can help us make smarter decisions about what we eat. Have you ever worried that everyone could tell you were nervous? Maybe before giving a presentation, going on a date, or walking into an interview? Most of us assume our anxiety is obvious—but is it? The answer may surprise you. Listen as I reveal what researchers discovered about how well other people can actually read your emotions. https://pubmed.ncbi.nlm.nih.gov/9731312/ PLEASE SUPPORT OUR SPONSORS AIR DOCTOR: Head to ⁠https://AirDoctorPro.com⁠ and use promo code SYSK to get $250 off select AirDoctor air purifiers, including the 3500, 4000, and 5500 models.

Curiosity is a powerful engine, and Something You Should Know is built on the idea that a single conversation can shift your perspective in a meaningful way. Host Mike Carruthers, through OmniCast Media, sits down with researchers, authors, and practitioners across a surprisingly wide spectrum-from neuroscience and health to social dynamics and personal finance. The aim isn't just to accumulate facts, but to uncover practical wisdom you can apply directly. You might hear a psychologist explain the simple habit that strengthens relationships, followed by an economist demystifying how to build lasting wealth, and then a physiologist breaking down the real science behind effective fitness. This podcast operates on the belief that improvement is multifaceted; a tip for saving time can be as valuable as understanding a new scientific discovery. Each episode is a self-contained dive into a topic that could very well change your approach to your career, your health, or your daily routine. The tone is conversational and grounded, focusing on actionable takeaways rather than abstract theory. By weaving together insights from the fields of science, education, and self-improvement, the show provides a toolkit for navigating life's complexities. It’s the kind of listening that leaves you with something concrete-a strategy, a new understanding, or a piece of advice that resonates long after the episode ends.
