Something You Should Know

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 belie...

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. Source: Dr. Daniel Amen author of Change Your Brain, Change Your Life https://amzn.to/3P3Dtld

Every day you negotiate — at work, at home, with friends, with strangers. Most of us think conflict is something to avoid or win. But according to William Ury, one of the world...

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 journali...

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 p...

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 ar...

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.

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 u...

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...

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 connecti...

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.

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...

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 str...

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?

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.

SYSK TRENDING takes a look back at conversations from the Something You Should Know archive that connect directly to topics people are talking about right now.

Motivation is one of them.

We tend to think people are motivated by carrots and sticks — rewards if you do what’s expected, punishment if you don’t. And while that approach can work in some situations, research shows it’s often not the most effective way to motivate yourself or others.

Daniel Pink explains what actually drives human motivation and why autonomy, mastery, and purpose matter far more...
