• Willpower is a mind-body response, not a virtue. It is a biological function that can be improved through mindfulness, exercise, nutrition, and sleep.
• Willpower is not an unlimited resource. Too much self-control can actually be bad for your health.
• Temptation and stress hijack the brain's systems of self-control, but the brain can be trained for greater willpower
• Guilt and shame over your setbacks lead to giving in again, but self-forgiveness and self-compassion boost self-control.
• Giving up control is sometimes the only way to gain self-control.
• Willpower failures are contagious--you can catch the desire to overspend or overeat from your friends­­--but you can also catch self-control from the right role models.

This delightfully accessible yet intellectually rigorous book transcends traditional boundaries between neuroscience, psychology and philosophy, to tackle the riddle of the unconscious mind. Freud bashing is a popular intellectual pastime these days (I myself have been guilty on occasion) but Mlodinow shows that by emphasizing the unconscious he was on the right track: we are completely unaware of the vast majority of events going on inside our brains. The book presents compelling evidence gleaned from a variety of sources to show that much of our behavior is governed not so much by our conscious mind– which is prone to claim credit – but by a cauldron of motives, drives and unconscious propensities of which we are largely oblivious. Indeed, most of our actions are carried out by the unconscious mind (or minds ) which exists in peaceful harmony with the conscious person "inside" your body.The question of why we are conscious of the tip of the iceberg of neural activity continues to remain elusive but, perhaps, the answer can be found by asking what you can do without being conscious; What’s the IQ of the unconscious mind? Here Mlodinow offers dazzling new insights into what the unconscious can and does do, to influence our lives.

Which is more dangerous, a gun or a swimming pool? What do schoolteachers and sumo wrestlers have in common? Why do drug dealers still live with their moms? How much do parents really matter? How did the legalization of abortion affect the rate of violent crime?

These may not sound like typical questions for an econo-mist to ask. But Steven D. Levitt is not a typical economist. He is a much-heralded scholar who studies the riddles of everyday life—from cheating and crime to sports and child-rearing—and whose conclusions turn conventional wisdom on its head.

Freakonomicsis a groundbreaking collaboration between Levitt and Stephen J. Dubner, an award-winning author and journalist. They usually begin with a mountain of data and a simple question. Some of these questions concern life-and-death issues; others have an admittedly freakish quality. Thus the new field of study contained in this book: freakonomics.

Through forceful storytelling and wry insight, Levitt and Dubner show that economics is, at root, the study of incentives—how people get what they want, or need, especially when other people want or need the same thing. InFreakonomics, they explore the hidden side of . . . well, everything. The inner workings of a crack gang. The truth about real-estate agents. The myths of campaign finance. The telltale marks of a cheating schoolteacher. The secrets of the Klu Klux Klan.

What unites all these stories is a belief that the modern world, despite a great deal of complexity and downright deceit, is not impenetrable, is not unknowable, and—if the right questions are asked—is even more intriguing than we think. All it takes is a new way of looking.

Freakonomicsestablishes this unconventional premise: If morality represents how we would like the world to work, then economics represents how it actually does work. It is true that readers of this book will be armed with enough riddles and stories to last a thousand cocktail parties. ButFreakonomicscan provide more than that. It will literally redefine the way we view the modern world.

On May 13, 1945, twenty-four American servicemen and WACs boarded a transport plane for a sightseeing trip over“Shangri-La,” a beautiful and mysterious valley deep within the jungle-covered mountains of Dutch New Guinea.Unlike the peaceful Tibetan monks of James Hilton’s bestselling novel Lost Horizon, this Shangri-La was home to spear-carrying tribesmen, warriors rumored to be cannibals.

But the pleasure tour became an unforgettable battle for survival when the plane crashed. Miraculously, three passengers pulled through. Margaret Hastings, barefoot and burned, had no choice but to wear her dead best friend’s shoes. John McCollom, grieving the death of his twin brother also aboard the plane, masked his grief with stoicism. Kenneth Decker, too, was severely burned and suffered a gaping head wound.

Emotionally devastated, badly injured, and vulnerable to the hidden dangers of the jungle, the trio faced certain death unless they left the crash site. Caught between man-eating headhunters and enemy Japanese, the wounded passengers endured a harrowing hike down the mountainside—a journey into the unknown that would lead them straight into a primitive tribe of superstitious natives who had never before seen a white man—or woman.

Drawn from interviews, declassified U.S. Army documents, personal photos and mementos, a survivor’s diary, a rescuer’s journal, and original film footage, Lost in Shangri-La recounts this incredible true-life adventure for the first time. Mitchell Zuckoff reveals how the determined trio—dehydrated, sick, and in pain—traversed the dense jungle to find help; how a brave band of paratroopers risked their own lives to save the survivors; and how a cowboy colonel attempted a previously untested rescue mission to get them out.

By trekking into the New Guinea jungle, visiting remote villages, and rediscovering the crash site, Zuckoff also captures the contemporary natives’ remembrances of the long-ago day when strange creatures fell from the sky. A riveting work of narrative nonfiction that vividly brings to life an odyssey at times terrifying, enlightening, and comic, Lost in Shangri-La is a thrill ride from beginning to end.

Hampton Sides is the editor-at-large forOutsidemagazine and the author of the international bestsellerGhost Soldiers, which won the 2002 PEN USA Award for nonfiction and the 2002 Discover Award from Barnes&Noble, and also served as the basis for the 2005 Miramax filmThe Great Raid.

Although World War II was the greatest conflict in the history of this planet, many a jaded reader has come to the reluctant conclusion that there aren’t any more World War II stories left to tell. At least not good ones—not tales of the “ripping good yarn” variety. Yet remarkably, in his new bookLost in Shangri-La, Mitchell Zuckoff has found one, and he’s told it with reportorial verve, narrative skill, and exquisite pacing.

What makes this World War II story all the more fascinating is that it isn’t really a war story—not in a strict military sense. It’s more of an exotic adventure tale with rich anthropological shadings. In 1945, near the end of the war, an American plane crashes in a hidden jungle valley in New Guinea inhabited by Stone Age cannibals. 21 Americans die in the crash, but three injured survivors soon find themselves stumbling through the jungle without food, nursing terrible wounds and trying to elude Japanese snipers known to be holding out in the mountains.

The first contact between the three Americans and the valley’s Dani tribesmen is both poignant and comical. The Americans, Zuckoff writes, have “crash-landed in a world that time didn’t forget. Time never knew it existed.” The tribesmen, who have never encountered metal and have yet to master the concept of the wheel, think the American interlopers are white spirits who’ve descended on a vine from heaven, fulfilling an ancient legend. They’re puzzled and fascinated by the layers of “removable skin” in which these alien visitors are wrapped; the natives, who smear their bodies in pig grease and cover their genitals with gourds, have never seen clothes before.

The Americans, in turn, are pretty sure their boartusk-bestudded hosts want to skewer them for dinner.

What ensues in Zuckoff’s fine telling is not so much a cultural collision as a pleasing and sometimes hilarious mutual unraveling of assumptions. Though the differences in the two societies are chasmic, the Americans and the Dani become—in a guarded, tentative sort of way—friends.

But when armed American airmen arrive via parachute to rescue the survivors, relations become more tense. The Americans make their camp right in the middle of a no-man’s land between warring Dani tribes—a no-man’s land where for centuries they have fought the battles that are central to their daily culture. Here, Zuckoff notes, the ironies are profoundly rich. The Dani, untouched by and indeed utterly unaware of the great war that’s been raging all acrossthe globe, become thoroughly discombobulated when their own war is temporarily disrupted.

Yes, therearestill a few good World War II stories left to tell. And yes, this one meets all the requirements of a ripping good yarn. Zuckoff, who teaches journalism at Boston University, is a first-rate reporter who has spared no expense to rescue this tale from obscurity. His story has it all: Tragedy, survival, comedy, an incredibly dangerous eleventh-hour rescue, and an immensely attractive heroine to boot. It’s extraordinary that Hollywood hasn’t already taken this tale and run wild with it. If it did, the resulting movie would be equal partsAlive,Cast Away, andThe Gods Must Be Crazy. It’s as though the Americans have arrived in the Stone Age through a wormhole in the space-time continuum. The Dani don’t know what to do with themselves—and life, as any of us know it, will never be the same.
