"Physiological constraints confine our bodies to less than one-fifth of the earth's surface. Beyond that fraction lie the extremes. What happens when we go to them?" "Dr. Kenneth Kamler has spent years observing exactly what happens. A vice president of the legendary Explorers Club, he has climbed, dived, sledded, floated, and trekked through some of the most treacherous and remote regions in the world. A consultant for NASA, Yale University, and the National Geographic Society, he has explored undersea caves, crossed the frozen Antarctic wastelands, and stitched a boy's hand back together while kneeling in knee-deep Amazonian mud."

"The words extreme and survival have lost some of their value from overuse and media hype. By showing us what happens when life is at stake and the body's capacities are put to their greatest test, this book reminds us what these words truly mean. Divided into six sections - jungle, high seas, desert, underwater, high altitude, and outer space - Surviving the Extremes uses firsthand testimony and documented accounts to illustrate what goes on in environments where our instinctive survival strategies must become fully engaged. These stories reveal how infinitely complex are the workings of the human body - and also how heartbreakingly fragile. At the core of this book is a request for the source of our will to survive and the haunting question of why some can and others cannot summon its awesome and nearly mystical power at their moment of greatest need."--BOOK JACKET.
