Some people think humans are natural pleasure seekers. But not psychologist Paul Bloom. In his new book, “The Sweet Spot,” Paul says we’re pain seekers, too. Just think about all the uncomfortable things we do for fun — eating spicy food, climbing treacherous mountains, watching scary movies, engaging in BDSM. Why do that stuff? According to Paul, it’s because pain can enhance pleasure, chosen suffering can make you more resilient, and adversity can suffuse your life with meaning. We can all benefit from a little discomfort, and in this intimate conversation with Next Big Idea Club curator Susan Cain, Paul explains how to fit more of it into our lives.

History, in the eyes of legendary investor Ray Dalio, is a perpetual motion machine. Nations rise and fall according to an inevitable cycle where peace and prosperity are always followed by depression and war. And in his new book, “Principles for Dealing with the Changing World Order,” Ray says the United States is now in the downward part of that cycle.

“The average human lifespan is absurdly, terrifyingly, insultingly short.” So begins Oliver Burkeman’s new book, “Four Thousand Weeks: Time Management for Mortals.” Make it to 80, and you’ll get about 4,000 weeks. And so, as the poet asked, “What will you do with your one wild and precious life?” For most of us, the answer is obvious: Get busy. Why squander what little time we have? But in this conversation with Next Big Idea Club curator Malcolm Gladwell, Oliver proposes an alternative. If you want to make the most of your time, he says, you have to stop chasing pointless productivity and embrace life’s finitude.

When it comes to Elon Musk, it can be hard to separate the man from the myth. But in her new podcast, “The Evening Rocket,” Harvard historian and New Yorker writer Jill Lepore manages to see through Musk’s mystique, explain his worldview, and decipher his visions of the future by going back to the sci-fi stories he grew up on — stories, Lepore says, that Musk sometimes misread.

To fret is human. That’s according to recent estimates that suggest 90 percent of the population experiences anxiety. And because anxiety, even in mild forms, can zap our confidence, squelch our sex drives, isolate us from friends and loved ones, most of us have concluded that anxiety is pretty much always a bad thing. But not neuroscientist Wendy Suzuki. In her new book, “Good Anxiety: Harnessing the Power of the Most Misunderstood Emotion,” she argues that we should treat anxiety like a form of energy. “Think of it as a chemical reaction to an event or situation,” she writes. “Without trustworthy resources, training, and timing, that chemical reaction can get out of hand—but it can also be controlled and used for valuable good.” Today, Wendy sits down with Lauren Miller Rogen (she's a filmmaker and the co-founder, along with her husband, actor Seth Rogen, of the non-profit Hilarity for Charity, which provides a range of free services to support families impacted by Alzheimer’s) to discuss the science-backed tools you can use to worry well.

Why is it so hard to break bad habits and replace them with good ones? You may think it all comes down to willpower. But social psychologist Wendy Wood says that if you really want to change your life, you need to tap into your unconscious mind. She would know. Wendy is the world’s foremost expert on habits and the author of “Good Habits, Bad Habits: The Science of Making Positive Changes That Stick.” Today, she chats with Next Big Idea Club curator Adam Grant about harnessing the science of habit formation to improve your life for the better. This conversation was among the first that we aired on this podcast, and we left a lot of great moments on the cutting room floor. Today, we’re restoring them. What follows is an extended version of Wendy and Adam’s conversation with new insights about overcoming chronic lateness, developing sustainable exercise routines, and making New Year’s resolutions that last past February.

When Dr. Vivek Murthy became U.S. Surgeon General in 2014, he went on a listening tour. What he heard surprised him. Americans were lonely, and it was killing them. In this deeply personal conversation with Next Big Idea Club curator Susan Cain (author of “Quiet”), Murthy makes the medical case for love and friendship.

The science is clear: people who engage in spiritual practices live longer, happier, healthier lives. For the past few years, two researchers — Dave DeSteno, who runs the Social Emotions Lab at Northeastern, and Lisa Miller, founder of the Spirituality Mind Body Institute at Columbia — have been trying to figure out why. They’ve found that treating religious rituals as tools we can adapt to our individual needs and values can help all of us — staunch atheists and devout believers alike — live more meaningful, successful, and connected lives. In this episode, Dave and Lisa share what they’ve learned, discuss the fraught relationship between science and organized religion, and offer tips for making the most of your holiday rituals.

What if everything we think we know about the history of our species is wrong? That’s the provocative question at the heart of a new book by today’s guest, David Wengrow. Hailed as fascinating, brilliant, and potentially revolutionary, “The Dawn of Everything: A New History of Humanity” debuted at no. 2 on the New York Times bestseller list. Drawing on the latest research in archeology and anthropology, it suggests that the lives of our ancient ancestors were not nasty, brutish, and short. On the contrary, they were playful, collaborative, and improvisational—and there's a lot they can teach us about how to improve the world as we know it.

In “Dopamine Nation: Finding Balance in the Age of Indulgence,” Dr. Anna Lembke says today’s superabundance of pleasurable stimuli makes us all vulnerable to overindulgence. But don’t lose hope. Anna, the medical director of addiction medicine at Stanford, says that by understanding how modern stimulants — from Instagram to masturbation machines — prey on our primitive brains, we can find ways to overcome the unhealthy dependencies that prevent us from leading balanced lives.

From the time she was in high school, Shellye Archambeau had one dream: she wanted to run a business. Ultimately, she pulled it off, becoming one of Silicon Valley’s first Black female CEOs. But getting there was far from easy. She had to learn how to assemble a network of mentors, overcome imposter syndrome, and challenge herself in ways she could never have imagined. The story of how she did it is the subject of her inspiring book “Unapologetically Ambitious: Take Risks, Break Barriers, and Create Success on Your Own Terms,” which was named one of the best of the year by our Next Big Idea Club curators. Today, one of those curators, Susan Cain, chats with Shellye about developing resilience, overcoming adversity, cutting yourself a break when it comes to work-life balance, and pursuing your ambition even if you’re an introvert.

Friends aren’t just fun to hang out with and handy in a pinch. They’re also a biological necessity. Rufus talks to journalist Lydia Denworth, author of the book "Friendship: The Evolution, Biology, and Extraordinary Power of Life's Fundamental Bond," about why friends — even the online variety — make us happier, healthier, smarter, and more successful.

We’ve all seen the meme. Two images, side by side. On the left, a photo of Jeff Bezos circa 1998. His hair is receding, his smile geeky, his sweater bulky and brown. The caption? “I sell books.” Then, on the right, there’s Jeff in 2017. His pate is as smooth as Lex Luther’s, his biceps as bulbous as Vin Diesel’s, a satisfied look on his sunglassed face. "I sell whatever the f**k I want,“ reads the caption. That meme is a pretty good metaphor for the era of radical change through which we are living, an era Azeem Azhar calls "the exponential age." Breakneck advances in technology allowed a humble bookseller to become chieftain of the world’s largest online retailer. And don’t expect those technological advances to slow down anytime soon. In the next few decades, new developments in everything from AI and 3D printing to synthetic biology and gene-editing won’t just change the way we live: they’ll allow already monolithic companies to keep growing at an unprecedented pace while our elected leaders scramble to keep up. The gap between rapidly advancing technology and our slow-moving society is the subject of Azeem’s marvelous new book, “The Exponential Age: How Accelerating Technology is Transforming Business, Politics and Society.” Recently named one of the best books of the year by the Financial Times, it’s at once a rousing survey of the new technologies that may change the way we live and, at the same time, a pointed reminder that those transformations will have profound political, economic, and social consequences.

Colleges, businesses, and bureaucracies have long operated on an "old power" model — rigid hierarchies that rule from the top down. But Henry Timms says that paradigm is going extinct. In his book, "New Power: How Power Works in Our Hyperconnected World — and How to Make It Work for You," Timms argues there's another force emerging. It's transparent, collaborative — and it's going to embolden all of us to change the world from the bottom up.

In this special episode, three writers share the hard-won wisdom they acquired running track, coaching hockey, and attending surf camp in Costa Rica. First, Olympic runner Alexi Pappas tells us what her career has taught her about self-reliance, mental health, embracing pain, and achieving her dreams. Next, John U. Bacon shares the surprising lessons he learned coaching the country's worst high school hockey team. And finally, journalist Tom Vanderbilt makes a compelling case for being an amateur athlete at any age.

Look up the term “Renaissance man” in the dictionary, and you'll probably find a photo of Antonio Damasio. He is a polyglot, an avid reader of fiction, a classical music aficionado, a student of modern philosophy, and an enthusiastic collector of art. This on top of his day job as a neuroscientist, professor, co-director of USC’s Brain and Creativity Institute, and author of brilliant books like “Descartes’ Error” and, most recently, “Feeling & Knowing.” Today, he chats with Rufus about where our feelings come from, how our brains and bodies interact, and the orgiastic pleasure of social admiration (and no, that is not a typo).

Our curators — Malcolm Gladwell, Adam Grant, Susan Cain, and Daniel Pink — recently named “The Extended Mind” by Annie Murphy Paul one of the best books of the year. In this episode, Annie returns to the Next Big Idea podcast for a spirited conversation with Adam in which she defends the fine art of fidgeting, suggests ways to improve group brainstorms, and gives Adam advice on how to talk to his childhood sensei. By the way, Adam's brilliant TED podcast "WorkLife" is back now with a new batch of interviews — including a Nobel Prize winner, one of the world’s most influential leaders, a daredevil who’s mastered fear, and one of the most decorated Olympians ever. Find them on "WorkLife with Adam Grant" wherever you listen.

Are you lazy? Social psychologist Devon Price doesn’t think so. In their provocative new book, “Laziness Does Not Exist,” Devon invites us to imagine a world where we stop judging other people for being lazy, stop shaming ourselves for being unproductive, and start realizing that doing less is not a moral failure.

When Katy Milkman was a newly minted professor at Wharton, she came across a statistic that stopped her cold: 40 percent of premature deaths result from personal behaviors we can change. Katy decided to do something about that, and for the next decade, she conducted groundbreaking research into the science of achieving lasting behavior change. In “How to Change: The Science of Getting From Where You Are to Where You Want to Be,” she shares what she’s learned. The Next Big Idea Club named “How to Change” one of the best books of the year, and in this episode, Katy sits down with our curator Daniel Pink to tell him why a change in the weather can help you save money, how Harry Potter got her in better shape, and what an accidental breakthrough in mathematics reveals about boosting your self-confidence.

In his new book, “Rationality: What It Is, Why It Seems Scarce, Why It Matters,” Steven Pinker writes: “When humans set themselves the goal of improving the welfare of their fellows … and they apply their ingenuity in institutions that pool it with others’, they occasionally succeed. When they retain the successes and take note of the failures, the benefits can accumulate.” In this episode, Steven argues that those benefits would accumulate even faster if we all learned a bit of logic, got better at sniffing out fallacies, embraced institutions that safeguard empirical truths, and entertained the idea that halting, imperfect progress may be better than no progress at all.

What if the fates of careers, companies, even entire industries depend on nurturing crazy ideas? In “Loonshots," physicist turned biotech entrepreneur Safi Bahcall pulls back the curtain on history’s greatest scientific, technological, and entrepreneurial breakthroughs, introducing us to a cast of colorful characters with much to teach us about how innovation really happens. In doing so, he provides a brand new framework for understanding the delicate relationship between complex ideas and even more complex people.

The deadline is one of the most powerful tools we have for getting work done. So why are we all so afraid of it? After studying organizations that manipulate deadlines to their advantage, Christopher Cox (former chief editor of Harper's and executive editor of GQ) has figured out how to transform deadlines from something to be feared into a superpower to boost productivity and stimulate creativity. He’s bottled his findings in a new book called “The Deadline Effect: How to Work Like It's the Last Minute—Before the Last Minute,” and in this episode, he shares what he has learned with novelist Rivka Galchen.

Over the past century, the average human lifespan has doubled. That astonishing statistic is the subject of a new book and PBS series by acclaimed science writer Steven Johnson called “Extra Life: A Short History of Living Longer.” In this episode, he tells Rufus about the renegades who shamed milkmen, spiked public reservoirs, and rode rocket-powered sleds — all in the name of science. They discuss how inventions like vaccines, seatbelts, and sewers made the world a safer place. And they peer into a future where aging might be a thing of the past.

Every season, we invite the authors of the best new non-fiction to distill their books into five big ideas. Then they read those ideas aloud. We call these book bites, and our app has hundreds of them. In this special episode, we’re sharing three book bites that demystify the art and science of parenting. Journalist Melinda Wenner Moyer offers evidence-based strategies for teaching your kids not to be jerks. Two educators explore the science behind the iconic TV show “Mr. Rogers’ Neighborhood.” And acclaimed economist Emily Oster explains how geeking out on data can make you a better parent.

Cognitive neuroscientist Christian Jarrett believes your personality is not etched in stone. Instead, he says, it's made of soft clay, and with the right tools, you can sculpt it to lead a happier, healthier, more satisfying life.

Conventional wisdom tells us that real joy comes from within: from exercise or meditation, acts of service or the way we look at the world — pretty much anything except material possessions. But author/designer Ingrid Fetell Lee offers a different take in her book “Joyful: The Surprising Power of Ordinary Things to Create Extraordinary Happiness.” Last season, Ingrid sat down with Next Big Idea Club curator Adam Grant to discuss the powerful relationship between the way we feel and the objects that surround us. Turns out we can harness that relationship to live healthier, happier lives. If you haven’t heard this episode before, you’re in for a treat. And if you have heard it before, there’s never a bad time to be reminded that joy is all around if you know where to look.

Adam Neumann, handsome, clever, and rich, with a comfortable home (eight of them, actually) and a happy (if slightly hyperactive) disposition, seemed to unite some of the best blessings of existence; and had lived forty years in the world with very little to distress or vex him. In the summer of 2019, he was presiding over the most valuable startup in America: WeWork. To the cynical, it was a glorified desk rental company. To Adam, it was the company that would “elevate the world’s consciousness,” broker Middle East peace, build offices on Mars (presumably with the staple WeWork perks: ping pong, cold brew, free beer), and turn Adam into history’s first trillionaire. But then the searing sun of reality melted the wax that held his wings together, and he plummeted to earth, the value of his company going up in smoke behind him, like a contrail. The story of Adam’s spectacular rise and calamitous fall is the subject of a new book called “The Cult of We: WeWork, Adam Neumann, and the Great Startup Delusion.” It was written by two Wall Street Journal reporters, Eliot Brown and Maureen Farrell. Their real-time coverage of Adam’s erratic behavior and flagrant self-dealing helped to hasten his demise. In this episode, they speak with Mike Isaac, author of “Super Pumped: The Battle for Uber,” about hubris, greed, tech culture, and bad judgment.

We do it 25,000 times a day, but most of us rarely give breathing a thought. Author James Nestor says we’re missing out on one of the most powerful pathways to health and happiness. He leads Rufus through the ins and outs of intentional breathing, revealing its potential to clear our minds, heal our bodies, and help us achieve incredible things.

Do we have alcohol to thank for civilization? The answer, according to Edward Slingerland’s new book, “Drunk: How We Sipped, Danced, and Stumbled Our Way to Civilization,” is a resounding yes. Edward, who’s a professor at the University of British Columbia and self-proclaimed “philosophical hedonist,” says that far from being an evolutionary fluke, our taste for alcohol is an evolutionary advantage — one that we’ve relied on for millennia to help us lead more social, creative, and pleasurable lives.

A lot of us run away from tough conversations. Anna Sale runs toward them. For nearly a decade, as the host of the podcast “Death, Sex & Money,” she has been having searching conversations about “the things we think about a lot and need to talk about more.” Now, in her new book, “Let’s Talk About Hard Things,” she blends reportage and memoir to reveal how speaking openly (and listening attentively) can fortify our relationships. That may sound simple, but as one of the book’s reviewers observed, “As vaccinated people begin to have joyous reunions with friends and family, after a year of isolation and Zooms, many of us are realizing that we’ve forgotten how to talk about the easy things, let alone the hard ones.” In this conversation, Anna — with her trademark warmth, curiosity, and candor — reminds us how to have those difficult conversations.

Malcolm Gladwell’s extraordinary new book, “The Bomber Mafia,” tells the story of a group of pilots who met on a muggy airbase in central Alabama and hatched a plan to revolutionize warfare. This was in the 1930s, the era of the bomber, a new breed of aircraft that could supposedly drop a bomb from six miles up and land it in a pickle barrel. If you could do that, you wouldn’t have to level cities, rack up casualties, or send a single soldier onto the battlefield. Planes could win wars all by themselves. Or so the young pilots thought. “The Bomber Mafia” is about how that dream unraveled in World War II, but because this is a Malcolm Gladwell book, it’s about a lot of other things, too, like a Dutch computer genius, a British psychopath, and pyromaniacal chemists at Harvard. It also dares to ask a vexing moral question: what happens when a piece of technology that heralds positive change is driven off course? To listen to “The Bomber Mafia,” visit thebombermafia.com

Teddy Roosevelt once said that nothing is worth doing “unless it means effort, pain, and difficulty.” And to that bestselling author Greg McKeown says, “Baloney!” There’s no denying that hard work often leads to positive results, but it can just as easily lead to exhaustion, apathy, and burnout. In his script-flipping new book, “Effortless: Make It Easier to Do What Matters Most,” Greg asks: “What if instead of pushing ourselves to — and in some cases well past — our limit, we sought out an easier path?” And in this easy-going conversation with author Jon Acuff, he shares some of the answers he’s come up with.

Have you ever lain awake at night, obsessing over a conflict with a colleague or a relative or a politician you’ve never met? That’s what journalist Amanda Ripley calls high conflict. If good conflict is the kind of friction that’s serious and intense but that leads somewhere useful, then high conflict is the kind of friction that gives you rope burn. It’s bitter, all-consuming, unproductive — and worst of all, once you find yourself embroiled in high conflict, it’s almost impossible to get out. Luckily, Amanda has been studying up on the tools you need to break free, and in this episode, she shares those tools with Next Big Idea Club curator Susan Cain.

Modern life has not been easy on our brains. Average IQ scores rose steadily throughout the last century. Now they appear to be leveling off. The problem, according to neuroscientists, may be that we have reached our neurobiological limits. Our brains simply can’t work any harder. Luckily, science writer Annie Murphy Paul has a solution. In her bold new book, “The Extended Mind: The Power of Thinking Outside the Brain,” she draws on a wealth of scientific research to show that we’re smarter when we get out of our heads. By offloading our memories onto our phones, making decisions based on our bodily sensations, using tactile tools to solve abstract problems, drawing inspiration from our surroundings, and arguing with our friends, we can access intelligence that exists beyond the confines of our craniums. In this episode, Annie explains how to do it.

Is it really so bad to be a little bit delusional? Not according to Shankar Vedantam. In his new book, “Useful Delusions: The Power and Paradox of the Self-Deceiving Brain,” he argues that we tell ourselves lies in order to live. We believe our marriages will last, even though there’s a fifty-fifty chance we’re headed for divorce. We trick ourselves into thinking our children are extraordinary because if we saw them for who they really are — average, disobedient, smelly — the body blows of parenting would be more than we could bear. In this candid conversation with Next Big Idea Club curator Daniel Pink, Shankar says wide-eyed delusions aren’t bad for us. In fact, self-deception is part of being a well-adjusted human being.

In 1958, a psychologist named Frank Rosenblatt took a five-ton computer, fed it a steady diet of punch cards, and taught it how to recognize the letter “A.” He called his creation the Perceptron, and his belief in its potential was like that of a deliriously proud parent. One day, he thought, the artificial intelligence he’d built would learn to recognize faces, speak like a human, translate languages, reproduce itself on an assembly line, and even fly to space — at which point, it would no longer be a computational marvel but a fully conscious being. The fact that you’ve never heard of the Perceptron tells you that none of Rosenblatt’s predictions came to pass — not in his lifetime, anyway. But a small band of brainy rebels never lost faith in the potential of AI to change the world. Thanks to their perseverance — along with dramatic improvements in computing power — they managed to make Rosenblatt’s prophecies a reality. The AI they built is what enables Facebook to recognize faces in the photos you upload. It’s the reason Siri and Alexa can (sometimes) understand what you’re saying, and Google can translate anything you write into 109 languages. Cade Metz has spent years chronicling the rise and rise of AI, first as a reporter at the New York Times and now in his new book, “Genius Makers.” In this forward-looking conversation, he tells Rufus what AI can do, where it’s headed, and whether we should be worried that supercomputers will wage war against humanity.

Ownership is simple, right? Something is either yours or it isn’t. Case closed. But who owns the space behind your airplane seat, the results of the DNA you took online, the Netflix password you got from your cousin’s roommate? The jury's still out, according to law professors Michael Heller and James Salzman. That’s because ownership isn’t binary or static: it’s a storytelling exercise, and we rely on just six stories to claim everything we own. In this revelatory conversation, Michael and James explain how those stories work, how you can use them to your advantage, and why they might be key to dismantling income inequality and arresting climate change.

You’ve posted a photo of your vaccine card on Instagram. The CDC says it’s okay to leave your bunker. Some of your friends have expressed interest in taking off their masks, breaking the six-foot barrier, and hanging out with you. Do you remember how? Whether you’re anxious about leaving your house or impatient to trade your house slippers for blue suede shoes, we could all use a refresher on how to connect with our fellow humans ... in person — and in a way that is not just pleasant but meaningful. That’s why we’re dusting off one of our favorite episodes, a conversation with Priya Parker, whose book, “The Art of Gathering: How We Meet and Why It Matters,” is essential post-pandemic reading.

What’s the first thing you do when you wake up in the morning and the last thing you do before bed? If you’re a modern knowledge worker, your answer is probably “check my email.” Makes sense. Your inbox is a busy place, which is why you peek at it, on average, every six minutes: constant vigilance is the only way to keep up. But all that checking comes at a cost. Communication overload undermines your productivity, erodes your focus, zaps your energy, and makes you miserable. Luckily, Cal Newport, the Georgetown professor and productivity whiz who came up with “deep work” and “digital minimalism,” has a plan for a post-email future, one where you can concentrate on work that really matters. And in this episode, he shares practical strategies that you can start using now to free yourself from the tyranny of the inbox.

Our work consumes us. But does it have to? Anthropologist James Suzman has spent decades living in the Kalahari Desert with one of the world’s last hunter-gatherer societies, and he’s concluded that our modern attitudes about work don’t mesh with the views held by our ancestors. For 95 percent of human history, we spent the bulk of our time doing … nothing. What changed? In this millennia-spanning conversation with Next Big Idea Club curator Adam Grant, James makes the case for spending less time toiling away at labor we loathe and more time working at things we love.

Almost a decade ago, the biochemist Jennifer Doudna and her team at Berkeley figured out how to rewrite our genetic code using a system called CRISPR. Thanks to this miraculous discovery, we now have the power to hunt down cancer cells, deflect oncoming viruses, and cure genetic diseases. But CRISPR has a dark side, morally speaking. In a world where we’ll soon have the power to endow our kids with superior strength and intelligence, how far is too far? Doudna’s groundbreaking discovery and the moral dilemmas that followed are the subject of a new book by best-selling biographer Walter Isaacson. In this expansive conversation, he tells Rufus why the CRISPR era will be far more consequential than the digital revolution. Plus, they discuss the mechanics of creativity, the delicate balance between competition and collaboration, and the personality traits that Isaacson’s subjects — Doudna, da Vinci, Ben Franklin, Einstein, and Steve Jobs — all have in common.

What’s for dinner? How will we answer that question in 50 years? In this thought-provoking (and occasionally hunger-inducing) conversation, science journalist Amanda Little tells Rufus that the single biggest threat posed by climate change is the collapse of our food systems. Provisions we love, like coffee and wine, are losing their flavor. And crops we rely on, like corn and soy, are getting harder to grow. If we don’t change our agricultural practices, we won’t be able to feed the globe’s swelling population. But don’t lose hope. Amanda says that if we can combine the wisdom of traditional farming practices with radical advances in agricultural technology, we might be able to create a healthier, more sustainable, and perhaps even more delicious future.

Whether or not we care to admit it, we all talk to ourselves. A lot. The voice in our heads yaks it up about half the time we’re awake, and it can speak at a rate of 4,000 words per minute. When it really gets going like that, not everything it says is particularly helpful. We’ve all gotten stuck dwelling on the past, worrying about the future, or standing idly by as our inner monologue devolves from introspection into negativity. Experimental psychologist Ethan Kross calls those moments chatter. “When the inner voice runs amok and chatter takes the mental microphone,” he writes, “our mind not only torments but paralyzes us.” Luckily, there are tools we can use to take back the mic, and in this episode, Ethan talks Rufus through them.

Humor is no laughing matter. It inspires innovation, strengthens relationships, disarms tension, and makes you look smart. Seriously. So why are we all afraid to be funny at work? In their new book, “Humor, Seriously,” Stanford professors Jennifer Aaker and Naomi Bagdonas say the recipe for professional success and personal fulfillment is to lighten up, pack a little levity in your briefcase, and start living your life on the precipice of a smile. In today’s episode, they dig into the neuroscience of laughter, share tips for crafting office-safe jokes, and help Rufus improve his comic chops.

A few years ago, as he watched his young daughter try out one hobby after another, a thought crossed Tom Vanderbilt’s mind: Why do we work so hard to get our kids to learn new skills when most of us adults stopped trying new things ages ago? For Tom, that contradiction became a call to arms. In defiance of the usual objections — it’s too late! you’re too old! — he took up chess, surfing, singing, juggling, and drawing. His goal wasn’t to gain mastery. He just wanted to prove to himself (and the eventual readers of his wonderful new book) that no matter how old you are or untalented you feel, being a beginner is a great way to stimulate your brain, meet new people, and bring a little adventure into your life.

We’re taught that the mark of surefire intelligence is the ability to think and learn. But in his new book, “Think Again,” Adam Grant says that in our turbulent world, there’s a more important skill: the ability to rethink and unlearn. If you can learn how to revise your opinions, check your ego, and admit when you’re wrong, then you’ll be on a path toward wisdom and joy.

Sure, opposable thumbs are handy. But in his brilliant new book, “This Is the Voice,” John Colapinto says the voice is our species’ greatest attribute. We rely on it to communicate and collaborate, woo our mates and protect our children, make art and win wars. John would know. A rock ‘n’ roll vocal injury changed his relationship with his instrument and set him on a path to better understand what his voice means to him — and what the voice means to humanity.
