Have you ever noticed that your period seems to sync up with your friends, roommates, sisters, or coworkers? Maybe you’ve even joked that you’ve been spending so much time together that your cycles decided to join forces.

But is period syncing actually a thing—or is it just one of those ideas we’ve all accepted without really questioning it?

In this episode of Wondering About..., we’re going down the rabbit hole of period syncing. Where did the idea come from? What does the research actually say? And why do so many people feel like they’ve experienced it?

We’re looking at the science behind menstrual cycles, the study that helped popularize the idea of menstrual synchrony, and what researchers have discovered since. Along the way, we’ll wonder about biology, coincidence, perception, and why our brains are so good at noticing patterns.

Is your period really syncing with your friends…or are we just really good at finding connections?

Come wonder with us.

What makes a great youth sports coach? Is it about teaching the game, building confidence, winning, or simply helping kids learn to love the sport?

In this episode of Wondering About..., we’re sitting down with our friend Erika Kelly to talk about youth sports coaching and what it really means to coach kids today.

Erika shares her coaching philosophy and what has shaped the way she approaches working with young athletes. We talk about what it means to coach the whole person—not just the athlete. What happens when coaches look beyond performance and pay attention to a child’s confidence, character, relationships, emotions, and development? How can coaches challenge kids while still creating an environment where they feel supported and valued?

We dive into the world of club vs. high school sports, talking about the differences between the two, what each can offer young athletes, and how families navigate the choices and expectations that come with competitive sports.

And, of course, we’re wondering about parents. How involved should parents be? Where is the line between being supportive and putting too much pressure on a young athlete? And how can coaches and parents work together to create a healthier experience for kids?

It’s a conversation about competition, confidence, development, participation, and the adults who have the opportunity to shape a young athlete’s experience.

Because youth sports are about so much more than the scoreboard.

Come wonder with us.

Have you ever wondered how easily you are influenced?

In this episode of Wondering About…, we’re diving into the fascinating science of influence. We start with a seemingly innocent Tiktok that led us down the rabbit hole of pharmaceutical reps and gifts to the psychology of reciprocity, familiarity, authority, and social proof. We explore the subtle ways other people can shape what we think, what we choose, and what we do.

And here’s the twist: research suggests we’re pretty good at recognizing bias and influence in other people, while being much less likely to recognize it in ourselves.

So are we really as independent-minded as we think we are?

We’re wondering about drug reps, free lunches, advertising, friendships, social media, and all the invisible nudges happening around us every day.

Because maybe the most interesting question isn't “Am I being influenced?”

It’s “Who—or what—is influencing me?”

Have you noticed the beautiful kitchens, homemade bread, flowing dresses, gardens, and slower-paced home life showing up all over social media? Welcome to the world of Tradwives.In this episode of Wondering About, we’re wondering what the Tradwife trend is really all about. What exactly is a Tradwife? Where did the term come from? Why has this lifestyle become so popular online—and what is it about the aesthetic that has so many people fascinated?We dig into the rise of Tradwife influencers, the appeal of homemaking and a slower lifestyle, and the difference between what we see on social media and what everyday life might actually look like behind the perfectly curated posts.Is Tradwife life a return to simpler living? A social media aesthetic? A reaction to our increasingly busy lives? Or a little bit of all three?Pour yourself a cup of coffee, put the sourdough in the oven, and come wonder with us!

Why are we so fascinated by true crime?

In this episode of Wondering About, we’re going down a rabbit hole to figure out why so many of us are drawn to stories about murder, mystery, danger, and the darker side of human nature.

Is it morbid curiosity? Are we trying to learn how to protect ourselves? Do we like the thrill of being scared from the safety of our own couch? Or are we simply wired to want to understand things that frighten us?

And then there are the people who take it a step further—the “keyboard detectives” who research cases, connect clues, develop theories, and sometimes become determined to help solve a crime.

We’re wondering why true crime has such a hold on us, why women make up such a large part of the audience, and what psychology can tell us about our fascination with the stories we probably shouldn't be listening to right before bed.

It’s a little creepy, a little fascinating, and a whole lot to wonder about.

Come wonder with us.

Have you ever wondered why some words are considered “bad” in the first place? Who decided which words we’re not supposed to say—and why does yelling one after stubbing your toe somehow make you feel a little better?

In this episode of Wondering About, we’re wondering about curse words. Where did they come from? Why are certain words considered offensive? Does swearing actually affect our brains and bodies? And why do the words that shock one generation barely get a reaction from the next?

We dig into the history and science behind profanity, find out what research says about people who swear, and—of course—talk about our own relationship with those four-letter words.

So whether you swear like a sailor or still spell out the bad words, this episode is for you.

What the @#$% is it about curse words? Come wonder with us!

Get to Know Us

We’ve spent a lot of time on Wondering About asking questions, researching random rabbit holes, and talking about the things that make us curious. But there’s one thing we haven’t really wondered about yet: each other.

In this episode, we’re turning the questions on ourselves and taking the time to get to know the two women behind the microphones. We’re sharing our stories, our personalities, the things we love, and some of the little details you might not know about us.

Think of it as a chance to pull up a chair and get to know us beyond the podcast.

Because if we’re going to wonder about everything else, we figured it was probably time to wonder about each other.

Come get to know us—and come wonder with us!

Have you ever wondered why making friends as an adult feels so much harder than it used to? When we were younger, friendships seemed to just happen. Now, between work, family, busy schedules, and life in general, finding—and keeping—close friends can take a little more effort.In this episode of Wondering About, we’re wondering about adult friendship. Why is it harder to make friends as we get older? How many hours does it actually take to turn an acquaintance into a real friend? Where are adults supposed to meet new people? And what does the research say about why friendship is so important to our happiness and well-being?We dig into the research, share some of our own friendship experiences, and talk about what it really takes to make meaningful connections in adulthood.Because apparently finding your people after 40 might require more than just sitting next to someone on the playground.Come wonder with us!Citations: "Hall, J.
