hopeful news [for those] suffering from functional bowel disease.”  — New York Times Book ReviewDr. Gershon’s groundbreaking book fills the gap between what you need to know—and what your doctor has time to tell you.Dr. Michael Gershon has devoted his career to understanding the human bowel (the stomach, esophagus, small intestine, and colon). His thirty years of research have led to an extraordinary rediscovery: nerve cells in the gut that act as a brain. This "second brain" can control our gut all by itself. Our two brains—the one in our head and the one in our bowel—must cooperate. If they do not, then there is chaos in the gut and misery in the head—everything from "butterflies" to cramps, from diarrhea to constipation. Dr. Gershon's work has led to radical new understandings about a wide range of gastrointestinal problems including gastroenteritis, nervous stomach, and irritable bowel syndrome.The Second Brain represents a quantum leap in medical knowledge and is already benefiting patients whose symptoms were previously dismissed as neurotic or "it's all in your head."

    These are the headlines of history, but they cannot be properly grasped without understanding the role that population has played.The Human Tide shows how periods of rapid population transition -- a phenomenon that first emerged in the British Isles but gradually spread across the globe--shaped the course of world history. Demography -- the study of population -- is the key to unlocking an understanding of the world we live in and how we got here. Demographic changes explain why the Arab Spring came and went, how China rose so meteorically, and why Britain voted for Brexit and America for Donald Trump. Sweeping from Europe to the Americas, China, East Asia, the Middle East, and North Africa, The Human Tide is a panoramic view of the sheer power of numbers.

    For five years in his mid-twenties, he sailed on the BEAGLE around the world, exploring jungles, climbing mountains, trekking across deserts. With every new landfall, he had new adventures: he rode through bandit country, was thrown into jail by revolutionaries, took part in an armed raid with marines, survived two earthquakes, hunted and fished. He suffered the terrible cold and rain of Tierra del Fuego, the merciless heat of the Australian outback and the inner pangs of heartbreak. He also made the discoveries that finally led him to formulate his theory of Natural Selection as the driving force of evolution. The five-year voyage of the BEAGLE was the basis for all Darwin's later work; but it also turned him from a friendly idler into the greatest scientist of his century.
