Endurance activities, like distance running, have existed since ancient times. But humans' relationship to those pursuits has changed, according to time and place. In the West, we've currently turned endurance sports into a science — tracking every metric and chasing personal records through sophisticated technology and personalized training plans. But as my guest, who's spent years studying the running cultures in different societies, knows well, this modern, individualized, data-driven approach isn't the only way to pursue the art of endurance. Michael Crawley is a competitive runner, social anthropologist, and the author of To the Limit. On the show today, we first examine how Western athletes have "workified" running through technology and social media. We then look at how other cultures approach running differently, including why East African runners emphasize group training over individual goals and how the Rarámuri people of Mexico incorporate spiritual dimensions into their running. We end our conversation with how we might rediscover more meaningful, holistic ways to approach our own physical pastimes.

These days, you hear more and more about parents and adult children being estranged from each other. Some individuals have even decided to go "no contact" with their parents; they don't want anything to do with their mom and/or dad at all. To understand what's behind this phenomenon, today I talk to Joshua Coleman, a psychologist who's spent 40 years counseling families and the author of Rules of Estrangement: Why Adult Children Cut Ties and How to Heal the Conflict. Joshuagoes beyond the typical one-sided narratives around parent-child estrangement that tell the story of parents who got what they deserved or overly entitled adult children who wrongly blame their parents, to unpack the larger cultural context for why these tensions have arisen. We discuss how society has moved from upholding a honor-thy-father-and-mother sense of obligation to prioritizing individuality and optionality, and why despite the fact that we're more child-focused and psychologically aware than ever, familial estrangements are on the rise. We get into the common reasons for estrangement, the role that expanding ideas of what constitutes abuse and trauma and an adult child's therapist can play in it, and how much parents can really be blamed for how their kids turn out. And we get into what parents who are estranged from their children can do to reconcile with them. Even if you're not personally estranged from a family member, the discussion of the underlying dynamics influencing all our modern relationships is a fascinating one.

Think about a hot loaf of bread fresh out of the oven. There's a lot going on with that loaf. On one level, it's a literal food that's been created through chemical processes. A delicious — your mouth might be watering right now — form of sustenance. But there's also more to it than that. There's something about bread, the so-called staff of life, that's different from other foods and resonates on a deeper level. There's a reason bread has been a rich symbol throughout times and cultures and figures prominently in religious scriptures. Today on the show, Peter Reinhart will take us on an exploration of the many facets of bread, from the spiritual to the scientific. Peter is a baker, educator, and the author of numerous books, including The Bread Baker's Apprentice: Mastering the Art of Extraordinary Bread. In the first half of our conversation, Peter unpacks the deeper, mystical meanings of bread by walking us through the twelve steps of how it's made. We then get into why sourdough is the future and final frontier of bread, and the technical secrets to mixing, fermenting, and baking a killer loaf.

It’s not uncommon for former law enforcement officers and intelligence agents to write self-help books where they share how the lessons they learned in their professional careers can apply to people in any walk of life. What is rare is for one of these officers-turned-authors to publicly prove they know what they’re talking about and that their tips work, as Derrick Levasseur did by winning the reality show Big Brother. Derrick is a former undercover detective, current private investigator, and the author of The Undercover Edge: Find Your Hidden Strengths, Learn to Adapt, and Build the Confidence to Win Life’s Game. Today on the show, Derrick shares how he became an undercover police officer, what he learned from that job, how he applied those lessons on Big Brother, and how you can use similar techniques to influence others, know when someone is lying, and bounce back from adversity.

When it comes to weight management and all-around good metabolic health, we most often think about what to eat. But my guest would say that it's also crucial to think about when to eat, Emily Manoogian is a chronobiologist and clinical researcher at the Salk Institute for Biological Studies. Today on the show, Emily shares how to create an optimal schedule for a healthy metabolism by aligning your eating schedule with your circadian rhythm. She explains when to start eating after waking, when to stop eating before bed, the importance of sticking to a set schedule, and what happens to your metabolism when you don't follow these timing guidelines. We also talk about how to best distribute your calorie intake throughout the day and how to eat to mitigate the metabolic problems that come with being a shift worker.

In 18th century America, this book was second in popularity only to the Bible. It was a favorite of many thinkers and leaders throughout history, including Emerson, Napoleon, Machiavelli, Nietzsche, and even President Truman. Yet, you probably haven't read it. It's Plutarch's Parallel Lives. If you're not familiar with Plutarch's Lives, you're in for a treat, as today's episode offers a great intro. My guest, Alex Petkas, found that even though he's a former classicist and professor, Plutarch's Lives is still a tough read, which is why he started a podcast, The Cost of Glory, to make it more accessible to people. He does the same thing on today's episode, sharing the background on Plutarch's set of biographies and its major themes. Alex explains why Plutarch thought that biography was a powerful way to transmit morals and how the Homeric virtue he had in mind differed from that of just having good, upstanding character. Alex then gives us a taste of Plutarch as we discuss the lives of two obscure Greek and Roman figures. We end our conversation with how to get started studying Plutarch yourself.

This episode starts off a little differently than others — with a short quiz, something called the Brief Sensation-Seeking Scale, which will tell you whether you're what psychologists call a high sensation-seeker or a low sensation-seeker. Read the following eight statements, and then pick a number from 1 to 5 that corresponds to your level of agreement, where 1 is "Not at all like me," 2 is "Not like me," 3 is "Unsure or both like and not like me," 4 is "Like me," and 5 is "Very much like me." I would like to explore strange places. I would like to take off on a trip with no pre-planned routes or timetables. I get restless when I spend too much time alone. I prefer friends who are excitingly unpredictable. I like wild parties. I would love to have new and exciting experiences, even if they are illegal. I would like to try bungee jumping. I would like to do frightening things. Now add up all the numbers together. If you scored between 8 and 16, you are a low sensation-seeker. If you scored between 16 and 28, you're about average for sensation-seeking. If you scored over 28, you're a high sensation-seeker. Today on the show, I unpack what these categories of personality mean with Dr. Kenneth Carter, a clinical psychologist, a professor, and the author of Buzz!: Inside the Minds of Thrill-Seekers, Daredevils, and Adrenaline Junkies. Ken explains how sensation-seeking exists on a spectrum between chill seekers, who like safety and calm routine, and thrill seekers, who enjoy chaos, risk, and novelty. He shares how there are actually four components to high sensation-seeking, and which two tend to get people in trouble. And we talk about whether being high or low sensation-seeking is a matter of nature or nurture, how high sensation-seekers fare in romantic relationships and what they should consider in choosing a career, and what the world's chill seekers can learn from its thrill seekers.

“Nothing takes the taste out of peanut butter quite like unrequited love,” Charlie Brown once said. Indeed, being spurned by one's crush, or, for that matter, by a friend or potential employer, not only ruins the taste of one's favorite sandwich spread, but causes great psychological distress and even physical pain. Here to walk us through one of life's worst feelings is Mark Leary, a professor of psychology and neuroscience at Duke University, and the editor of Interpersonal Rejection. Today on the show, Mark unpacks the experience of social rejection, including why we're so sensitive to it and the emotions and behaviors it causes, which can be positive and prosocial or maladaptive and even violent. We discuss the role that is played by the sociometer, a concept Mark originated, in monitoring our social acceptance and rejection and what influences its sensitivity to fluctuations in your relational value. And Mark offers advice on how to remove some of the sting of rejection and civilly reject others.

Note: This is a rebroadcast. Nietzsche's maxim, "What doesn't kill you makes you stronger," isn't just a sound philosophical principle. It's also a certifiable physiological phenomenon; toxins and stressors that could be deadly in large doses, actually improve health and resilience in smaller, intermittent ones. The ironic thing, my guest points out, is that it's the fact that we're not getting enough of this sublethal stress these days that's really doing us in. Paul Taylor is a former British Royal Navy Aircrew Officer, an exercise physiologist, nutritionist, and neuroscientist, and the author of Death by Comfort: How Modern Life is Killing Us and What We Can Do About It. Today on the show, Paul discusses the science of hormesis, how small doses of intermittent stress can make us more resistant to chronic stress, and why you need to embrace what Paul calls "discomfort harvesting." We talk about some now-familiar topics like fasting and cold and heat exposure with fresh inspiration as to how important they are to practice and how to do them effectively. We discuss how hot a sauna needs to be to get the benefits of heat exposure, Paul's suggestion for how to make an ice bath on the cheap, what may be the single best type of food to eat to improve your gut's microbiome, a form of fasting that's got anti-cancer benefits but is so accessible it won't even feel like fasting, what supplement to take to mitigate the effects of a bad night's sleep, and much more. We end our conversation with how to use what Paul calls a "ritual board" to stick with your healthy habits and resist the "soft underbelly" of modern life.

In creating the Jack Reacher character, Lee Child launched a series of books that now boast 100 million copies in print and have been turned into movies and a popular Amazon streaming series. Today on the show, I talk to Lee about what makes Reacher so compelling and much more. We first discuss how Lee didn't get started with writing until he was almost forty, and what prompted him to change careers. We then unpack the Reacher character, discussing the ancient, archetypal roots of this vigilante, drifter detective, what he has in common with the knight errant, and the enduring appeal of the lone wolf. We also talk about Lee's writing process, why midlife is the best time to write, and why, after writing more than two dozen Reacher novels, he's chosen to hand off the series to his brother and fellow writer, Andrew.

Money can't buy happiness. It sounds good as a bumper sticker platitude. But the truth is, money can buy happiness. At least sometimes. In certain circumstances. If we view it and use it in the right ways. Here to unpack the conditions under which money can buy happiness and facilitate our flourishing is Dr. Daniel Crosby, a psychologist and behavioral finance expert and the author of The Soul of Wealth: 50 Reflections on Money and Meaning. Today on the show, Daniel shares the minimum income level at which money buys happiness, at least in the sense of avoiding pain. We talk about how to purchase material things in a way that increases happiness, while avoiding materialism, and the value of using your money to buy health and freedom. And we discuss the importance of finding an overarching why that guides the way you allocate your money and doing a values audit to see if your purpose and spending habits are aligned.

Are leaders born or made? Judging by the 50 billion dollar leadership development industry, the answer is definitely the latter. From schools to workplaces, everyone is seen as a potential leader and expected to become one by undergoing leadership training. My guest questions the assumptions underlying this phenomenon, which he calls "the leadership industrial complex," and says that the cult of leadership, and its idea that everyone can and should become a leader, can create burnout and unhappiness. Elias Aboujaoude is a Stanford professor of psychiatry and the author of A Leader's Destiny: Why Psychology, Personality, and Character Make All the Difference. Today on the show, Elias describes the state of the leadership industrial complex, the mathematical impossibility it forwards that everyone can be a leader and no one is a follower, and the primary presumption it makes that leadership can be taught. Elias argues that, in fact, a lot of what makes for good leadership is innate and potentially unchangeable. We discuss the implications of this fact, and why it's actually okay not to want to be a leader.

When people think about living more fully and making better use of their time, they typically think of finding some new organizational system they can structure their lives with. Oliver Burkeman says that what you really need instead are perspective shifts — small, sustainable changes in how you view and approach your day-to-day life. He provides those mindset shifts in his new book, Meditations for Mortals: Four Weeks to Embrace Your Limitations and Make Time for What Counts. And we talk about some of them today on the show, including why you should view life's tasks and problems like a river instead of a bucket, stop feeling guilt over your "productivity debt," make peace with your decisions by embracing an unconventional reading of the poem "The Road Not Taken," aim to do your habits "dailyish," be more welcoming of interruptions, and practice "scruffy hospitality."

We often think of the difference between a boy and a man as a matter of age. But Brian Tome says that there can be 15-year-old men and 45-year-old boys, and that the real difference maker in being grown up isn't a matter of the number of years you accumulate but the qualities, behaviors, and mindset you possess. Brian is a pastor and the author of The Five Marks of a Man. Today on the show, Brian unpacks what he thinks are the marks of mature manhood. We talk about the need to have a vision and how life-giving hobbies can create that vision. Brian argues that manhood requires staking out a minority position, being part of a pack, and creating more than you consume. And we discuss the ways men can still be protectors in the 21st century.

Imagination is the ability to form mental images and concepts that don't exist or haven’t happened yet, think outside of current realities, and form connections between existing ideas to create something new and original. If the number of movie sequels and the outsized popularity of music made decades ago is any measure, our current age is suffering from a deficit in imagination. And indeed, tests show that creativity, which takes the possibilities generated in the mind and produces something with them, has been in decline for many years now — a phenomenon that has repercussions for our personal edification, professional advancement, and societal flowering. But if our imagination has indeed atrophied, the good news is that it can be strengthened. So argues my guest, Albert Read, the former managing director of Condé Nast Britain and the author of The Imagination Muscle: Where Good Ideas Come From (And How to Have More of Them). Today on the show, Albert shares his ideas on how our imagination can be built back up. We discuss how to get better at observation and how to use a commonplace book and the way you structure your reading to cross-pollinate your thinking and generate more fruitful ideas. We also discuss how to overcome the unthinking habit, resist stagnation as you age, and embrace imaginative risk.

In an age that doesn't think too much about history, you might be forgiven for thinking that a culture of exercise only emerged in the 20th century. But the idea of purposefully exercising to change one's body — what folks used to call "physical culture" — likely goes back to the very beginnings of time. Here to unpack the origins, evolution, and future of fitness is Dr. Conor Heffernan, a Lecturer in the Sociology of Sport at Ulster University and the author of The History of Physical Culture. Today on the show, Conor takes us on a fascinating and wide-ranging tour of physical culture, from the ancient Egyptians, who made their pharaohs run around a pyramid to test their fitness to rule, to the ancient Greeks who used their gymnasiums for both bodily training and intellectual philosophizing, to modern strongmen who became proto fitness influencers, and many periods and societies in between. We discuss how training practices changed over time, where they may be going next, and the evergreen principles from past eras that we could still learn from today.

Do you have trouble feeling comfortable when socializing? Maybe sometimes you do fine, but other times you feel nervous, shy, and awkward. Or maybe socializing always feels like a struggle. Either way, you know how frustrating and even debilitating social anxiety can be. It cannot only lead to avoiding potentially enriching experiences and a failure to make desired connections, it can sometimes be hard to understand. So what's going on when you socially misfire? Here to unpack that question is Thomas Smithyman, who is a clinical psychologist and the author of Dating Without Fear: Overcome Social Anxiety and Connect. Today on the show, we get into the dynamics of social anxiety in both romantic and platonic contexts. Thomas explains what defines social anxiety, how it exists on a spectrum from mild shyness to an outright disorder, and what causes it, from genetics to faulty thinking. We talk about the protection strategies people often use to avoid the pain of social judgement, and why they actually backfire. We then get into what you can do to be more socially comfortable and confident, including a key to effective flirting, why you should try to make a "mediocre first impression," and how to find your way into what Thomas calls the "warm social world."

With over 300 million books sold, Louis L'Amour is one of the bestselling authors of all time. All 120 of his books remain in print. But the greatest story L'Amour ever penned was his own. He spent the early part of his life traveling in a circus, working as a lumberjack and miner, circling the world as a seaman, winning over 50 fights as a professional boxer, and serving in WWII. Today on the show, I talk about both the personal and professional aspects of Louis' life with his son, Beau L'Amour. We discuss some of Louis' adventures and the autodidactic education he gave himself by way of a voracious reading habit. We then turn to how Louis got started as a writer and how he cut his teeth writing for pulp magazines before breaking through as a Western novelist and becoming a blockbuster success in his sixties.

What if there was a supplement that could build muscle, maintain bone health, fortify the brain against cognitive decline due to age and stress, and alleviate depression, has been proven safe, and comes with almost no side effects? Well, there is such a supplement, it's been around a long time, and it isn't even expensive. It's creatine. Here to unpack the myths, benefits, and recommended ways to use creatine is Darren Candow, a professor of exercise physiology and nutrition who supervises the Aging Muscle and Bone Health Laboratory at the University of Regina. Darren specializes in studying creatine and has published over 70 papers on the subject. Today on the show, Darren explains how a supplement often associated with bodybuilders may actually be beneficial for just about everyone — athletes and non-athletes and the young and old alike. He unpacks what creatine does in the body, and how its benefits extend beyond the body and into the brain. He offers recommendations on the formulation of creatine to use, a suggested dosage and whether it should increase with age, and how to avoid the bloating effect. He also shares what we know about creatine's safety, including its effects on the kidneys, and whether it can cause hair loss.

Self-control, the ability to resolve a conflict between two competing desires, is frequently touted as the golden key to success. But many of the most popular ideas about self-control are actually at odds with how it really operates. Here to unpack some of the lesser-understood and counterintuitive ideas around discipline and willpower is Michael Inzlicht, a professor of psychology who has studied the nature of self-regulation in depth. In the first part of our conversation, Michael unpacks the popular ego depletion model of willpower and how it hasn't held up to scientific scrutiny. We then turn to the surprising fact that the people who seem to exhibit a lot of self-control don't actually exercise a lot of discipline and restraint in their lives, that the achievement of goals is more a function of having virtuous desires, and what contributes to having those desires.
