Something You Should Know

Memory feels dependable — we rely on it to tell the story of our lives. But the truth is, memory behaves in some surprisingly strange ways. For one thing, your brain forgets far more than it remembers, and that’s not a flaw — it’s actually part of how memory is designed to work. At the same time, certain moments stick with remarkable clarity while others fade almost instantly. Think about how vividly many people remember events from their late teens and early adulthood compared with other periods of life. So why do some experiences become unforgettable while others disappear? And if our memories are so selective and imperfect, can we do anything to improve them? Cognitive psychologist and memory expert Megan Sumeracki says yes. She explains how memory actually forms, why we often misunderstand how it works, and what science reveals about the best ways to strengthen it. Megan is an associate professor of psychology at Rhode Island College and author of The Psychology of Memory (https://amzn.to/4cCOAuK). In o

When was the last time you sighed? Probably not that long ago. We tend to think of sighing as something we do when we’re frustrated, tired, or relieved. But scientists have discovered that sighing plays a much deeper role in keeping your body functioning properly — and your brain actually has a built-in mechanism that triggers it. https://newsroom.ucla.edu/releases/ucla-and-stanford-researchers-pinpoint-origin-of-sighing-reflex-in-the-brain Some people naturally seem to expect things to work out, while others brace for disappointment. Is optimism simply a personality trait, or is it something you can learn? Psychologist Deepika Chopra — often called “The Optimism Doctor” and author of The Power of Real Optimism: A Practical, Science-Based Guide to Staying Resilient, Curious, and Open Even When Life Is Hard (https://amzn.to/4b9EG4S) — explains that real optimism isn’t about pretending everything is fine. It’s a mindset grounded in science that can improve resilience, decision making, health, and even longevit

A simple trip to get your hair cut can instantly make you look years younger — and it may have little to do with the haircut itself. There’s a subtle psychological shift that happens in that moment that changes how people see you… and how you see yourself. https://www.youbeauty.com/beauty/psychology-of-hair/ At some point, everyone faces the question: Do I stay, or do I go? A job that feels off. A relationship that’s complicated. A place that no longer fits. But discomfort doesn’t always mean it’s time to leave — and comfort doesn’t always mean you should stay. Emily P. Freeman, host of The Next Right Thing (https://emilypfreeman.com/podcast/) and author of How to Walk into a Room: The Art of Knowing When to Stay and When to Walk Away (https://amzn.to/43a6d1p), shares a thoughtful, practical framework for making life’s hardest decisions with clarity instead of panic. Some songs don’t just climb the charts — they change music. Tracks like “Good Vibrations,” “Rocket Man,” and “What a Fool Believes” didn’t jus

How you think about getting older might be more powerful than you realize. Scientists have uncovered an unexpected connection between people’s beliefs about aging and what happens to them as the years go by. https://pubmed.ncbi.nlm.nih.gov/12150226/ We’re often warned not to reveal too much about ourselves. Oversharing can make people uncomfortable, right? Maybe. But Harvard Business School professor Leslie John argues the bigger problem may actually be the opposite — sharing too little. In her book Revealing: The Underrated Power of Oversharing (https://amzn.to/3ME0EVt), she explains how thoughtfully sharing personal thoughts, experiences, and vulnerabilities can strengthen relationships, build trust, and even improve professional success. Humans have a strange relationship with technology. Some innovations instantly become essential while others quietly disappear. New technology can spark excitement, fear, resistance, and creativity all at once. Vanessa Chang, Director of Programs at Leonardo, the Interna

We spend a surprising amount of mental energy agonizing over decisions that ultimately don’t matter very much — what to order at a restaurant, which email to answer first, or which option might be “slightly better.” Meanwhile, the truly important decisions in life often don’t get the thoughtful attention they deserve. Annie Duke says that’s because most people misunderstand how good decision making actually works. Annie is a former professional poker champion who now advises organizations and leaders on how to make smarter choices under uncertainty. She is also the author of How to Decide: Simple Tools for Making Better Choices (https://amzn.to/3OQgGIF). In our conversation, she explains why we get stuck overthinking small decisions, why big decisions are often harder than they should be, and how adopting a more strategic way of thinking about choices can dramatically improve the outcomes we experience in life and work.

The average American unknowingly throws away up to $1,500 a year — and it’s happening right in your own kitchen. It’s not obvious. It doesn’t feel wasteful in the moment. But small, everyday habits quietly drain real money from your grocery budget. There are a few surprisingly simple shifts that can stop the leak. https://www.usda.gov/foodlossandwaste/consumers Your beliefs about yourself — your abilities, your limits, your future — quietly shape your behavior every day. “I’m too old.” “I’m bad with money.” “I’ll never succeed.” The problem is not that these statements are true — it’s that you believe them to be true. Nir Eyal, author of Beyond Belief: The Science-Backed Way to Stop Limiting Yourself and Achieve Breakthrough Results (https://amzn.to/3OLvImC), explains how limiting beliefs form, why they feel so real, and how deliberately reshaping them can dramatically alter your trajectory in work, relationships, and life. Is memory loss inevitable as you age? Are we destined for cognitive decline? Dr. Maj

Most of us have taken a hit to the head at some point — a fall, a collision, a stray ball — and brushed it off as no big deal. But what if those “minor” impacts aren’t so minor? Even seemingly harmless head injuries may have longer-term effects that we rarely consider.

Most of us think conflict is something to avoid or win. But according to William Ury, one of the world’s leading authorities on negotiation who has advised the White House, the Pentagon, and major corporations, there is a far more powerful approach. Listen as he reveals how to turn confrontation into collaboration and why the way you frame a dispute often determines its outcome.

Walk into a meeting room, classroom, or even your own living room, and chances are you’ll sit in the same spot you’ve chosen before. And if someone else is sitting there, it feels all wrong. But why? It’s a small behavior that reveals something surprisingly deep about how humans think. https://en.wikipedia.org/wiki/Place_attachment Every night your brain builds an alternate reality — sometimes magical, sometimes terrifying, often completely illogical. So what are dreams actually for? Are they random noise, emotional therapy, memory maintenance, or something else entirely? Award-winning health and science journalist Karen van Kampen, author of The Brain Never Sleeps: Why We Dream and What It Means for Our Health (https://amzn.to/3ZJwbIs) explains what researchers now understand about dreaming — and why your sleeping brain may be working harder than you realize. Taking care of your health can feel overwhelming — conflicting advice, complicated routines, endless “must-do” lists. But according to Dr. Zeke Emanu

What does it really mean to be happy? Even the happiest people aren’t happy all the time. Maybe happiness isn’t a constant emotion at all — maybe it’s a philosophy. A way of living. A sense of meaning shaped by what you do and who you do it for. Stephanie Harrison has spent years studying what truly makes people happy — and she believes many of us have been chasing the wrong version. She is the creator of the “New Happy” philosophy, a powerful rethinking of happiness that has reached millions through art, a newsletter, a podcast, and programs around the world. Her work has been featured in Fast Company, Forbes, and Harvard Business Review. You can learn more at https://www.thenewhappy.com.

Sometimes a great idea doesn’t come from thinking harder — but from shifting your body. Research suggests that posture can influence how creatively and flexibly you think, meaning the position you’re in during a brainstorming session could actually affect whether you have that “Eureka!” moment. Listen to how that works as we open this episode. https://pubmed.ncbi.nlm.nih.gov/27992759 It feels like everyone has allergies these days. But do they really? And what exactly qualifies as an allergy in the first place? Dr. Zachary Rubin, a double board-certified pediatrician and allergist/immunologist in the Chicago area and author of All About Allergies: Everything You Need to Know About Asthma, Food Allergies, Hay Fever, and More (https://amzn.to/401KdW5) explains why allergies appear to be on the rise, why many people think they have allergies but don’t, and what’s really happening inside your immune system when a true allergic reaction occurs.

Fresh flowers brighten any room — but they fade fast. You’ve probably heard all kinds of tricks to keep them alive longer: flower food packets, aspirin, sugar, even pennies in the vase. But there is one surprisingly simple additive that appears to work better than most, and it’s probably already in your kitchen. https://www.dailymail.co.uk/femail/article-12981249/ No matter how thrilling something feels at first — a new relationship, a promotion, a new gadget — the excitement fades. It has to. The brain is wired for habituation, meaning we quickly get used to what once thrilled us. But that doesn’t mean the spark is gone for good. Tali Sharot, professor of cognitive neuroscience at University College London and MIT, founder of the Affective Brain Lab and co-author of Look Again: The Power of Noticing What Was Always There (https://amzn.to/49F5vLD), explains how you can “resparkle” your life and reclaim appreciation for what you’ve started to take for granted.

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 potenti

Thirty-six percent of Americans — including 61% of young adults and 51% of mothers with young children — say they experience “serious loneliness.” Nearly everyone has felt that ache at some point: the quiet sense of isolation, of being unseen or disconnected, even when surrounded by people. Humans are not wired for isolation. We are built for connection. Yet modern life — with its screens, busyness, and fragmented communities — often pulls us further apart. Psychiatrist Dr. Edward Hallowell joins me to explain why loneliness is far more than a bad feeling. It impacts physical health, mental health, motivation, even lifespan. He shares why connection is essential to thriving — and practical ways to rebuild it in a world that makes isolation easy.

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

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. Source: Janine Driver author of You Say More Than You Think (https://amzn.to/3SPYVwt). 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.

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.

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

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.
