When men get sick with a cold or the flu, do they actually suffer more than women — or just complain louder? Some fascinating research suggests there may be real biological differences in immune response between the sexes, which could explain the infamous “man cold.” I break down what scientists have discovered and what it really means. https://pubmed.ncbi.nlm.nih.gov/29229663/

Picky eating feels normal today — separate meals for kids at the dinner table is often the norm. But it wasn’t always this way. For most of history, children ate what adults ate or they didn’t eat at all. Helen Zoe Veit, award-winning historian, associate professor at Michigan State University, and author of Picky: How American Children Became the Fussiest Eaters in History (https://amzn.to/3OolXKY) explains how and why picky eating became so common, the serious problems it creates — and why it doesn’t have to be that way.

Will artificial intelligence make us intellectually lazy — or is it about to unleash a new wave of human potential? Zack Kass, one of OpenAI’s first 100 employees and author of The Next Renaissance: AI and the Expansion of Human Potential (https://amzn.to/3MoYM2I) argues that tools like ChatGPT are only scratching the surface. He explains why AI may not replace human thinking but amplify it — if we use it wisely.

People form powerful judgments about you within seconds of seeing your online profile photo. Are you trustworthy? Competent? Approachable?

On a freezing morning, it feels smart to let your car idle and warm up before driving off. But is it? Modern engines aren’t built the way they used to be. In fact, letting your car sit and idle too long may not be doing what you think it is. This episode begins with what actually happens under the hood — and how long you really should wait before you hit the gas and go. https://www.mensjournal.com/gear/stop-idling-like-its-1985-warm-up-your-car-right

There are few communication situations more intense than when a Secret Service agent speaks with someone who has threatened the President of the United States. In those moments, connection, trust, and careful listening aren’t just helpful — they’re critical. Brad Beeler developed his communication skills in those exact circumstances and shares how anyone can apply those same techniques to everyday conversations. Brad served in many roles at the Secret Service including on the protection detail for President George H.W. Bush. He is author of Tell Me Everything: A Secret Service Agent's Proven Strategies for Earning Trust, Revealing the Truth, and Communicating with Anyone (https://amzn.to/3M5YlKy).

Designing a meaningful life may not be about discovering your one true calling or waiting for passion to strike. What if finding meaning is something you build through experimentation — by testing ideas, adjusting course, and learning from experience?

He is executive director of the Stanford Life Design Lab, founder of the Designing Your Life Institute, and co-author of How to Live a Meaningful Life: Using Design Thinking to Unlock Purpose, Joy, and Flow Every Day.

Body language sends signals we’re often unaware of — and apparently, that includes your belly button. Where it points can subtly communicate interest, attention, and even attraction. This episode begins with the surprising message your belly button may be sending — and what you might be picking up from others without realizing it.

Have you ever eaten when you weren’t hungry… or kept eating even though you were already full — and then wondered why you did that? Most people assume it’s about willpower. It isn’t. Dr. Jud Brewer explains what’s really driving those urges and how to break the cycle without dieting, restriction, or guilt. He’s a professor at Brown University’s School of Public Health and author of The Hunger Habit: Why We Eat When We’re Not Hungry and How to Stop. His work reveals how to stop fighting food — and actually enjoy it more (https://amzn.to/49sbiEw).

We like to believe we’re good at predicting the future — our careers, relationships, finances, and even how we’ll feel. But humans are notoriously bad at understanding randomness, coincidence, and probability. Why do coincidences seem so meaningful? Why does randomness never look random? And how does this distort the predictions we make about our own lives? Kit Yates joins me to unpack the science behind prediction — and when it’s smarter not to predict at all. He’s author of How to Expect the Unexpected: The Science of Making Predictions—and the Art of Knowing When Not To (https://amzn.to/3Ur3PRM).

If you’re a coffee drinker, you’ve probably wondered at some point whether you’re drinking too much. Coffee gets blamed for everything from poor sleep to heart trouble — but a major long-term study tells a very different story.

Eyeglasses are so common today that it’s easy to forget how revolutionary they are. Before glasses, millions of people were cut off from reading, learning, working, and fully participating in society. The invention of eyeglasses didn’t just improve vision — it reshaped education, labor, science, and culture. David King Dunaway joins me to tell this surprisingly underappreciated story. He’s a professor of English at the University of New Mexico and the University of São Paulo, and author of A Four-Eyed World: How Glasses Changed the Way We See (https://amzn.to/46nqL9y).

Most people avoid complaining — it feels awkward, time-consuming, or not worth the effort. But when you don’t complain, you often end up paying for mistakes that aren’t yours. When done the right way, complaining can be effective, respectful, and surprisingly rewarding. Eric Zse explains when to speak up, what to say, and how to get results without being rude or angry. He’s author of The Art of the Constructive Complaint: How to Speak Up, Get Heard, and Turn Everyday Frustrations into Fair Outcomes (https://amzn.to/45Sdi9L).

And finally — have you ever walked into another room and instantly forgotten why you went there? It happens to almost everyone, and it has a name: the doorway effect. We wrap up with the fascinating reason this happens — and why it has nothing to do with memory loss or aging. (https://pubmed.ncbi.nlm.nih.gov/21563019/)

Everyone seems more stressed than ever — and oddly, some people even wear it like a badge of honor. But chronic stress isn’t something to brag about. It quietly alters the way you think. It amplifies worry, exaggerates threats, narrows your options, and makes worst-case scenarios feel not just possible, but probable. Over time, stress doesn’t just affect your mood — it reshapes your perception, your judgment, and the decisions you make.

And because the shift happens gradually, you often don’t realize it’s happening at all.

Clinical psychologist Arthur Ciaramicoli has spent decades studying stress and its impact on the brain and behavior. In this conversation, he explains what’s actually happening neurologically when stress rises — how your brain shifts into a more reactive mode, why you become more negative and less flexible in your thinking, and how chronic stress can trap you in a self-reinforcing loop. We also explore why modern life seems perfectly designed to keep stress levels elevated and why simply “relaxing” isn’t a realistic solution.

Most importantly, Arthur shares practical, science-based strategies to interrupt the cycle — techniques you can use in the moment to calm your nervous system, widen your perspective, and prevent stress from distorting your thinking. If you’ve ever made a decision under pressure and later wondered, “What was I thinking?” — this episode will help you understand exactly what was happening and how to prevent it next time.

Arthur is the author of The Stress Solution (https://amzn.to/3yQgt22).

When a big storm is on the way, it happens like clockwork: empty shelves, frantic shoppers, and a sudden shortage of eggs, bread, and milk. Why do people panic-buy the same items every time? And how much do you actually need if you’re stuck at home for a few days? This episode begins with the psychology behind panic shopping — and why otherwise rational people behave this way. https://www.psychologytoday.com/us/blog/happy-trails/201601/panic-shopping-the-psychology-of-the-bread-milk-eggs-rush

Most of us don’t think of ourselves as vulnerable. We assume danger happens to other people — until it doesn’t. In reality, small, everyday behaviors can quietly increase or reduce your personal safety. The way you speak, move, and pay attention sends signals you may not even realize you’re broadcasting. Dannah Eve joins me to explain how street smarts really work and how to protect yourself using simple, practical awareness. She’s a personal safety educator and author of Street Smarts: Trust Your Instincts, Outsmart Danger, and Stay Safe in a World That Isn’t. (https://amzn.to/4roXfs8).

We love the idea of the sudden “aha” moment — the brilliant flash of inspiration that changes everything. But that’s rarely how great ideas actually happen. Most breakthroughs are the result of borrowing, refining, recombining, and sometimes stumbling onto something unexpected.

He’s an associate professor at the Rotman School of Management and author of How Great Ideas Happen: The Hidden Steps Behind Breakthrough Success. (https://amzn.to/4ab4L2J).

We’ve always been fascinated by twins. They seem mysterious, almost magical — as if they share a special connection the rest of us don’t.

Why would anyone need to be taught how to sleep, breathe, or drink water? Those are things you already do every day. And yet, it turns out most of us are doing them just wrong enough to undermine our health.

In this SYSK Trending episode, I talk with Michael Breus, one of the world’s leading sleep experts, about how small adjustments to when and how you sleep, breathe, and hydrate can produce outsized benefits for your energy, immunity, metabolism, and long-term health.

Dr. Breus is a double-board-certified clinical psychologist and sleep specialist, and the author of Sleep Drink Breathe: Simple Daily Habits for Profound Long-Term Health (https://amzn.to/3ZposzW). His research shows that better health doesn’t always require doing more—it often comes from doing the basics correctly.

This is simple advice, but it’s powerful—and it may change how you think about your daily habits.
