Something You Should Know

When you visit Disneyland or Disney World, something subtle happens in the parking lot both when you arrive and when you leave. Most people never notice it, yet it reflects a simple insight Walt Disney understood about human behavior — one that can make everyday experiences feel better and more memorable if you apply it in your own life.

We often talk about the “chemistry of love,” but the reality goes much deeper. Our attraction to others, the way relationships form, and even why love sometimes falls apart are strongly shaped by biology. Dr. Liat Yakir, a biologist specializing in genetics and science communication, explains how hormones, brain chemistry, and evolutionary forces influence who we fall for and how relationships unfold. She is the author of A Brief History of Love: What Attracts Us, How We Fall in Love and Why Biology Screws it All Up (https://amzn.to/3vkyiqn), and she shares fascinating insights into what’s really happening inside our brains and bodies when we experience love — along with a surprisingly practical prescription for building stronger relationships.

Many of us pay fees, higher prices, and miss opportunities simply because we never ask for something better. Yet asking for a waiver, a discount, or a different option can often save real money. Matt Schulz, chief credit analyst at LendingTree and author of Ask Questions, Save Money, Make More: How to Take Control of Your Financial Life (https://amzn.to/4a1xIgt), explains why so many people hesitate to ask, when asking works best, and how small conversations can lead to surprisingly big financial wins.

For some people, walking barefoot feels freeing and natural. For others, the idea seems unhealthy or even dangerous. Humans have been wearing shoes for tens of thousands of years, which raises an interesting question: are shoes protecting us — or weakening our feet? https://time.com/6284245/walking-barefoot-health-risks/

Junk mail seems like a relic of another era. Physical ads showing up in your mailbox feel easy to ignore in a world dominated by digital marketing. Yet companies still spend billions sending those mailers every year. Why? Because for certain groups of people, those pieces of mail are surprisingly effective — far more than you might expect. https://www.uspsoig.gov/sites/default/files/reports/2023-01/RISC-WP-20-009.pdf

Artificial intelligence is suddenly everywhere — writing emails, answering questions, summarizing documents, and even helping people make decisions. But should we trust it? Linguist Emily Bender, a professor at the University of Washington and one of the world’s leading voices urging caution about AI hype, argues that we may be misunderstanding what these systems actually do. Named to the inaugural TIME 100 list of the most influential people in AI, she explains why tools like ChatGPT can appear intelligent while operating very differently from human thinking. She is co-author of The AI Con: How to Fight Big Tech’s Hype and Create the Future We Want (https://amzn.to/3P1v6tn) and she offers an important perspective on how we should — and shouldn’t — rely on AI.

Humans have been drinking alcohol for thousands of years, and despite the well-known risks, it remains deeply embedded in cultures around the world. Why do people drink in the first place? Is alcohol simply a dangerous toxin, or does it serve psychological or social purposes that help explain its enduring appeal? Dr. Charles Knowles, Professor of Surgery at Queen Mary University of London and Chief Academic Officer at Cleveland Clinic London, brings both scientific expertise and personal experience to the discussion. Having struggled with alcohol dependency himself, he explores what alcohol does inside the body and brain, why some people develop problems while others do not, and how our culture shapes the way we think about drinking. He is the author of Why We Drink Too Much: The Impact of Alcohol on Our Bodies and Culture (https://amzn.to/4b8HHCd).

Razor blades are small, simple pieces of metal — yet they often cost far more than people expect. You may even notice they’re locked behind glass at many stores. Why are they so expensive, and why haven’t competitors driven prices down? Several companies have tried to disrupt the razor business but it hasn't gone as well as many consumers hoped. https://www.forbes.com/sites/andriacheng/2018/01/24/pgs-gillette-woes-have-translated-to-this-good-news-for-consumers/

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 our conversation, she shares fascinating insights about why our brains forget so much, why certain years of life seem packed with memories, and simple techniques anyone can use to remember more of what truly matters.

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 longevity.

Butter seems simple. It’s just butter… right? Not even close. The butter you buy at the grocery store hides a surprising amount of history, science, and culinary nuance — from why it’s shaped into sticks to why some butter is salted and some isn't. Anna Stockwell, New York–based recipe developer, food stylist, and author of The Butter Book ( https://amzn.to/47gj6u8), explains what actually makes butter different from one brand to another, when premium butter is worth it, and how understanding butter can dramatically improve the way you cook.

Many people use mouthwash every day as part of their routine. It seems like a healthy habit. But there’s growing evidence that regular use of some mouthwashes may come with an unexpected downside — one that most people never consider. https://pmc.ncbi.nlm.nih.gov/articles/PMC7125030

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 just become hits; they shifted the sound, the production, and even the business of rock and pop. Marc Myers, longtime Wall Street Journal contributor and author of Anatomy of 55 More Songs: The Oral History of Top Hits That Changed Rock, Pop and Soul (https://amzn.to/3TrynC4), takes us inside the stories behind these landmark recordings and explains what made them transformative.

When you walk into a store, you think you’re making rational choices. But before you touch a product or read a price tag, your senses are already at work — especially your sense of smell. Retailers carefully design scents to influence how long you linger, how you feel, and how much you spend. https://www.sciencedaily.com/releases/2009/12/091214143732.htm
