Something You Should Know

Take a look at your speedometer the next time you're driving. Chances are, it's lying to you. The speed you're actually traveling is probably different from what the dashboard says—and that's completely intentional. https://en.wikipedia.org/wiki/Speedometer?utm

From the time we're children, we're constantly reminded to "sit up straight" and "don't slouch." We've been told that good posture prevents pain, improves health, and even makes us more confident. But how much of that is actually supported by science? According to Beth Linker, surprisingly little. In this conversation, she explores where our ideas about posture came from, why so many assumptions have gone unchallenged, and what the evidence really says about the way we sit, stand, and move. Beth is a former physical therapist, medical historian, and author of Slouch: Posture Panic in Modern America (https://amzn.to/4480Hhk).

Imagine remembering names almost instantly, recalling conversations in remarkable detail, or memorizing enormous amounts of information with ease. It may sound like a rare gift, but Nelson Dellis says it's a skill almost anyone can learn. As a six-time USA Memory Champion, a two-time Guinness World Record holder and Grandmaster of Memory. He has mastered techniques that dramatically improve recall—and they're far simpler than most people imagine. In our conversation, Nelson explains how memory really works, why we forget so much, and the practical strategies you can start using immediately to remember more of what matters. He is author of Everyday Genius: Hacks to Boost Your Memory, Focus, Problem-Solving, and Much More (https://amzn.to/3Rlxpc7).

Tennis balls haven't always been bright yellow. For decades they were white, just as many people assume they always were. So why did manufacturers change one of the most recognizable pieces of sports equipment in the world? Interestingly, the answer has very little to do with tennis players—and everything to do with the people watching the match. https://www.itftennis.com/media/2280/balls-history-of-tennis-balls.pdf

Can simply believing a treatment will work actually help it work better? Surprisingly, yes. Researchers have found that your expectations can have a powerful effect on how your body responds to medication—even when the treatment itself hasn't changed. https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/placebo-effect

Most of us think of politeness as little more than saying "please" and "thank you." But good manners do much more than make social interactions pleasant. They help build trust, strengthen relationships, reduce conflict, and even influence how people judge our competence and character. So why are some people naturally more polite than others? Do the rules of politeness change depending on where you are or who you're talking to? And can you be blunt—or even rude—and still earn people's respect? Louise Mullany has spent more than 25 years studying the science of politeness. She is Professor of Sociolinguistics at the University of Nottingham and author of Polite: The Art of Communication at Home, at Work and in Public (https://amzn.to/3xVN9Jo).

You can outsource your résumé, polish your LinkedIn profile, and even use AI to help write a cover letter. But when it's time for the interview, it's all on you. Too many candidates hope they'll "just answer the questions," only to discover they weren't nearly as prepared as they thought. Sam Owens explains what hiring managers are really looking for, the mistakes that immediately hurt your chances, and how a little preparation can dramatically improve your performance—whether you're interviewing in person or over Zoom. Sam is founder of Sam's Career Talk (https://www.samscareertalk.com/) and author of I Hate Job Interviews: Stop Stressing. Start Performing. Get the Job You Want (https://amzn.to/4f7xJSX).

MSG has had a bad reputation for decades. Many people avoid it because they believe it's unhealthy or causes unpleasant reactions. But where did that belief come from? And does today's science actually support it? The answer is much more surprising than most people realize. https://health.clevelandclinic.org/is-msg-really-harmful

Have you ever pushed on a door that was supposed to be pulled—or pulled when you should have pushed? It feels embarrassing, but don't blame yourself. It turns out the problem usually isn't you. It's the door. https://uxdesign.cc/intro-to-ux-the-norman-door-61f8120b6086

Everyone has an accent—even if they don't think they do. The way you speak tells a story about where you've been, who influenced you, and sometimes even how other people perceive you before you've said more than a few words. Why do accents develop? Why are they so difficult to lose? And do people with accents realize they have one, or do they think everyone else sounds different? Erik Singer, one of Hollywood's leading dialect coaches, explains the fascinating science, history, and psychology behind the way we speak. He has analyzed accents from around the world for millions of viewers online (https://www.eriksinger.com/) and is author of the forthcoming book The Case of the Disappearing R.

We all replay conversations in our heads. We rethink decisions, relive embarrassing moments, and imagine what we should have said or done differently. It feels productive—as if we're solving a problem. But more often than not, we're simply trapped in a mental loop called rumination. Far from helping, rumination can fuel anxiety, depression, stress, and self-doubt while making it harder to move forward. Science journalist Donna Jackson Nakazawa explains why our brains get caught in these loops, why they're so difficult to break, and what actually works to quiet an overactive mind. She is author of Mind Drama: The Science of Rumination and How to Outwit Your Inner Defeatist (https://amzn.to/4vKWiNs).

You've probably heard the advice that couples who want happier relationships should simply have sex more often. It sounds logical—but research suggests the relationship between sex and happiness may work very differently than most people assume. https://www.cmu.edu/news/stories/archives/2015/may/more-sex-does-not-lead-to-happiness.html

What does it really mean to be successful? Most people would probably say it's about making more money, climbing the career ladder, earning recognition, or becoming well known. But what if we've been measuring success all wrong?

After spending years traveling the country as host of Dirty Jobs, Mike Rowe met thousands of people whose work is essential but rarely celebrated. Welders, plumbers, linemen, mechanics, farmers, and countless others showed him that fulfillment, purpose, and success often have very little to do with prestige—and a lot to do with attitude, craftsmanship, and showing up when it matters.

In this fascinating conversation, Mike challenges many of the assumptions we've come to accept about work, education, persistence, efficiency, and what it really takes to build a satisfying life. Even if you don't agree with all of his conclusions, his perspective is thoughtful, refreshing, and guaranteed to make you reconsider some deeply held beliefs.

Mike Rowe is creator and longtime host of Dirty Jobs, founder of the mikeroweWORKS Foundation (www.mikeroweworks.com), host of the podcast The Way I Heard It (https://mikerowe.com/podcast/), and author of the bestselling book The Way I Heard It (https://amzn.to/34Dikog).

Need a favor? The way you ask may matter as much as what you're asking for.

Going to therapy has become more common—and more socially accepted—than ever before. For many people, it has been life-changing. At the same time, anxiety, depression, and loneliness continue to rise, prompting an important question: Are we asking therapy to solve problems it was never designed to solve? Should everyone have a therapist, even if nothing is seriously wrong? Where is the line between normal struggles and issues that truly require professional treatment? In this thoughtful conversation, therapist Jonathan Alpert explores who benefits most from therapy, where it can fall short, and why resilience, personal responsibility, and strong relationships still play an essential role in emotional wellbeing. Jonathan has spent more than two decades treating patients and is author of Therapy Nation: How America Got Hooked on Therapy and Why It's Left Us More Anxious and Divided (https://amzn.to/4xMXS2I).

Birds are so common that it's easy to stop noticing them. Yet they are among the most extraordinary creatures on Earth. Every feather is a masterpiece of engineering. Their bones are optimized for flight. Some navigate across continents with astonishing accuracy, others build intricate nests without blueprints, and many possess abilities that scientists are still trying to understand. Even more remarkable, every bird alive today is a living descendant of the dinosaurs. Lorna Gibson, Professor of Materials Science and Engineering at MIT and lifelong bird enthusiast, reveals the hidden science behind feathers, flight, migration, and the incredible adaptations that make birds some of nature's greatest engineering achievements. She is author of Birds Up Close: An Engineer Explores Their Hidden Wonders (https://amzn.to/4eOiE9C).

The next time you open a bag of potato chips, pay attention to the sound it makes. That loud crinkling isn't an accident. Food manufacturers carefully engineer snack bags to produce a particular sound because what you hear can actually influence what you think about the freshness and quality of what's inside. https://www.mcgill.ca/oss/article/food/noisy-chip-bags
