For decades, some researchers have argued that the notable human capacity for endurance evolved from the hunting practices of our ancestors, which produced physiological adaptations that make us uniquely well suited for running.

But this theory has always had its detractors.

As my guest explains, a new study addresses these long-standing criticisms and adds evidence that, indeed, we were all born to run.

Alex Hutchinson is a journalist who covers the science of endurance and fitness, and today on the show, he explains what those criticisms were and how this new research counters them. We talk about the role running held amongst peoples of the past, how running is not only primal but cultural and even spiritual, and why we continue to run today, even though we’re not hunting for food. And we discuss how, even if we are born to run, that doesn’t mean everyone will always enjoy running all of the time, and how to get into running if you’re someone who doesn’t feel an innate desire for it.

In a family, a lot of the dynamics around devices and screens are reactive in nature. Kids bug for their own smartphones, parents worry they'll be left out without one, and without weighing the pros and cons, give in to their kids' requests. Parents let children have a ton of screen time because it lets the parents do what they want; then, they reach a moment where they feel disturbed about how much time their kids are on screens, berate their children for this habit, which they've facilitated, and vow that things are going to abruptly turn around.

Rather than basing your policies about kids and screens on mood, fear, and impulse, it would be better to do so based on reason and reflection. Emily Cherkin has some ideas on how to get there. Emily is a former teacher, a screentime consultant who helps parents and educators balance the role of devices in kids' lives, and the author of The Screentime Solution: A Judgment-Free Guide to Becoming a Tech-Intentional Family. Today on the show, Emily unpacks the state of screentime amongst kids today, how the "displacement hypothesis" explains how its impact extends beyond a decline in mental health, and why parents give their kids smartphones even when they're not sure it's good for them. We then turn to how families can become more tech intentional, and how that starts with parents taking a look at their own behavior. We discuss why putting parental controls on devices isn't the ultimate solution, why a better one is based on your relationship with your kids, why you need to live your digital life out loud, and some considerations to think through before getting your kid their first smartphone.

Although they may call it different things and approach its attainment in different ways, many of the world’s religions and philosophies have a similar goal: achieving a life of virtue, peace, and flourishing.

In his new book, Seriously Happy, Ben Aldrige explains how anyone can use the wisdom of ancient traditions to improve themselves and live the Good life. Today on the show, Ben offers a thumbnail sketch of Buddhism, Cynicism, Taoism, Stoicism, Epicureanism, and Aristotelianism, along with practices and challenges inspired by these philosophies, including walking a banana, listening to a music performance without music, and taking a Wu Wei adventure, that you can use to put ancient wisdom into action and become a better and happier man.

Note: This is a rebroadcast.

Over the last year, my 12-year-old son has been doing one challenge every week as a rite of passage and chance to earn a special trip. Some of these challenges have involved reading a book in a week, and the most recent book we gave him to read was How to Win Friends & Influence People by Dale Carnegie. His review? He said it was the best book he's read so far.

So a book written almost 90 years ago can still be a favorite of a kid in the 21st century. Talk about some staying power. 

The advice in How to Win Friends & Influence People, and Dale Carnegie's other classic, How to Stop Worrying and Start Living, is timeless. But to help introduce it to a new audience, my guest, Joe Hart, has recently co-authored the book Take Command, which synthesizes, updates, and adds to the principles of Carnegie's two perennial bestsellers. Joe is the President and CEO of Dale Carnegie & Associates, which continues Carnegie's work in the present day, and we begin our conversation with some background on the guy who kicked off this work back in 1936. We then talk about what principles we can take from How to Stop Worrying and Start Living on developing a positive mindset. From there, we talk about the big overarching principle of How to Win Friends & Influence People, and how you can use it to improve your relationships. We end our conversation with advice on how to live life with more intentionality and meaning.

As you get older, you can start to feel like you'll never achieve your dream or receive recognition for your contributions to a field, or that your best work is behind you.

Mo Rocca has compiled stories that demonstrate that you shouldn't give up hope, and that no matter your age, the best may yet be to come.

Mo is a humorist, journalist, and the co-author of Roctogenarians: Late in Life Debuts, Comebacks, and Triumphs. Today on the show, Mo shares the stories and lessons of entrepreneurs, artists, actors, and more who achieved greatness or adulation in their twilight years or had a new spurt of creativity when they thought the well had run dry, including KFC founder Colonel Sanders, the artist Matisse, a couple of guys who didn't receive their first war wounds until they were old enough to qualify for the senior citizen discount at Denny's, and even a virile 90-year-old tortoise.

Your relationship with your mother is likely the first and most foundational connection in your life. At its best, this bond can be a source of comfort, strength, and love that lasts a lifetime and changes in healthy, appropriate, and adaptive ways as you mature into adulthood.

But sometimes, the attachment between a mother and her son can become unhealthy, resulting in a phenomenon called mother-son enmeshment, in which a man can become a kind of surrogate husband to his mom.

Here to unpack this complex issue is Dr. Kenneth Adams. Ken is a clinical psychologist who has spent much of his career working with what he calls "mother-enmeshed men" and is the author of When He's Married to Mom. Today on the show, Ken unpacks the characteristics of mother-enmeshed men and how to know if you are one, and he explains what can happen in childhood that would cause a mother to enmesh with her son. We discuss the problems enmeshment can create in men's relationships and other areas of life and how it can lead to things like compulsive porn use. And we unpack what it means for a man to become independent and emancipate from his mother, how it's different from cutting her off, and what it looks like to have a healthy relationship with your mom.

You probably know your body follows a circadian rhythm, and probably think of it as primarily regulating your sleep/wake cycle, which it certainly does. But your body's internal clock also regulates many other physical, mental, and behavioral changes that occur every 24 hours, and working with your circadian rhythm, rather than against it, can boost your health and happiness.

Here to unpack how to do so is Russell Foster, a professor of circadian neuroscience and the author of Life Time: Your Body Clock and Its Essential Roles in Good Health and Sleep. In the first part of our conversation, we discuss some science and background on circadian rhythm and its connection to light exposure. We then turn to the practical implications of having an internal clock, including whether you need to worry about viewing blue light at night, the significant mental and physical harms that can accrue from working the night shift and what can be done to mitigate them, what influences your chronotype and whether you're a morning lark or a night owl, whether you should be concerned if you're waking up in the middle of the night, why you wake up to pee in the night, the best times of day to exercise, and how the circadian rhythm can influence when you should take medication.

A fair amount of gear is involved in making a camping or backpacking trip a success, and choosing that gear can be a little intimidating as there are lots of options, and it's expensive to boot.

Here to offer some tips on selecting gear and getting the most out of it is Craig Caudill, an avid outdoorsman, the director and lead instructor of the Nature Reliance School, and the author of Ultimate Wilderness Gear: Everything You Need to Know to Choose and Use the Best Outdoor Equipment. Today on the show, Craig and I discuss some things to know when purchasing things like boots, tents, sleeping bags, and more, and we offer some specific recommendations as to the gear that's worked for us respectively. Craig also offers tips on using outdoor equipment, including how to dry wet boots without damaging them, whether you should put a tarp under your tent, what to do if you get hot and sweaty or cold in your sleeping bag, a hack for sleeping more comfortably on the ground, and the best kind of knife for an outdoorsman to carry.

You may know Nate Silver as an election forecaster. But he’s a poker player as well. And his experiences operating in a world of competition and risk led him to explore what his fellow gamblers, as well as hedge fund managers, venture capitalists, and many other kinds of maverick types do differently than other people.

Amongst the findings Nate shares in his new book, On the Edge: The Art of Risking Everything, are the “13 habits of highly effective risk-takers.” Nate and I discuss some of these habits today on the show, including exercising strategic empathy, avoiding the pitfalls of resulting, taking a raise or fold stance toward life, and more.

To train the body, strengthening its muscles, increasing its cardiovascular health, and improving its agility, you need to do exercises like stretching, running, and lifting weights.

To train the soul, expanding its capacity, you likewise need to perform exercises, in this case, what are called "spiritual disciplines" — practices like fasting, silence, self-examination, study, and simplicity.

As a pastor, John Mark Comer approaches the spiritual disciplines from a Christian perspective, as the habits and practices from "the way of Jesus" that allow individuals to make deeper layers of themselves available to grace and access the transforming power that's necessary to become what John Mark calls "a person of love."

But the practices that are considered spiritual disciplines can be found across different religions, and even philosophies like Stoicism, and can be utilized by people from varied backgrounds to deepen their inner life and strength, center themselves in chaos, find greater purpose, and subdue baser desires to reach for higher ideals.

Today on the show, John Mark offers an introduction to the spiritual disciplines, and the way they can be an act of resistance, a way for us to form our own values and rhythms in life, instead of allowing our lives to be formed by the defaults and external forces of our age.
