Something You Should Know

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

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 International Society for the Arts, Sciences, and Technology and author of The Body Digital: A Brief History of Humans and Machines from Cuckoo Clocks to ChatGPT (https://amzn.to/4cqHjBE), explores how people historically absorb new technologies — and how those tools reshape the way we interact with each other and the world.

When you buy new clothes, it feels natural to wear them right away. After all, they’re brand new. But “new” doesn’t necessarily mean clean. In fact, clothing can go through quite a journey before it reaches your closet — one that may make you think twice before wearing it straight off the rack. https://www.southernliving.com/should-you-wash-new-clothes-before-wearing-11885557

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. Majid Fotuhi, world-renowned neurologist and author of The Invincible Brain: The Clinically Proven Plan to Age-Proof Your Brain and Stay Sharp for Life (https://amzn.to/4l5s1nZ), says no. He explains that brain health is deeply influenced by lifestyle — including 14 factors you can control — and that protecting your mind requires the same intentional care as protecting your heart or body.

When you need someone to say yes to a request, one short phrase can significantly increase your chances. It doesn’t manipulate. It doesn’t pressure. It simply taps into a powerful psychological principle that makes people more open to helping. https://brainblogger.com/2015/06/25/top-5-persuasion-techniques-of-2015/
