    Now, more than ever before, our country needs to see full legalization of medical/recreational marijuana and hemp. Any way you look at it, for whoever is using it, marijuana is a medicinal plant, in abundant supply. Every month and every year that goes by, we find out more positive things about it. Medicinal marijuana has been demonized through the years but obviously this plant has a great deal of positive attributes, and it’s also a renewable resource. Being a cash crop, marijuana is bad for the pharmaceutical industry. Is Big Pharma pressuring the government to continue to deny sick people access? If so, that’s truly a crime against American citizens. And as Ventura writes: “Our government won’t do the right thing and legalize marijuana unless we the people demand it, because there are so many people within our government on the payroll, all thanks to the War on Drugs." Jesse Ventura’s Marijuana Manifesto calls for an end to the War on Drugs. Just because something is illegal, that doesn’t mean it goes away, it just means that criminals run it. Legalizing marijuana and marijuana dispensaries will serve to rejuvenate our pathetic economy, and just might make people a little happier. Ventura’s book will show us all how we can take our country back.

    Tome was born in 1782 near present-day Harrisburg and lived on the upper Susquehanna for much of his life. He tells colorful (and mostly true) tales about his hunting exploits in the Pennsylvania wilderness, as he tracked elk, wolves, bears, panthers, foxes, and other large animals through the state’s north-central mountains, earning wide renown among his contemporaries. His stories contain suspenseful chase scenes, accidents, and narrow escapes, inviting the reader to view a still-wild Pennsylvania through the eyes of one who “was never conquered by man or animal.” Pioneer Life, originally published in 1854, has since been reprinted several times.

    John Mack. This eminent Harvard psychiatrist and Pulitzer Prize-winning biographer risked his career to investigate the phenomenon of human encounters with aliens and to give credibility to the stupefying tales shared by people who were utterly convinced they had happened.Nothing in Mack's four decades of psychiatry had prepared him for the otherworldly accounts of a cross-section of humanity including young children who reported being taken against their wills by alien beings. Over the course of his career his interest in alien abduction grew from curiosity to wonder, ultimately developing into a limitless, unwavering passion.Based on exclusive access to Mack's archives, journals, and psychiatric notes and interviews with his family and closest associates, The Believer reveals the life and work of a man who explored the deepest of scientific conundrums and further leads us to the hidden dimensions and alternate realities that captivated Mack until the end of his life.

    The calls to ban it were more or less instant.Re:cyclists is the tale of what happened next, of how we have spent two centuries wheeling our way about town and country on bikes--or on two-wheeled things that vaguely resembled what we now call bikes. Michael Hutchinson picks his way through those 200 years, discovering how cycling became a kinky vaudeville act for Parisians, how it became an American business empire, and how it went on to find a unique home in the British Isles. He considers the penny-farthing riders exploring the abandoned and lonely coaching roads during the railway era, and the Victorian high-society cyclists of the 1890s bicycle craze--a time when no aristocratic house party was without bicycles and when the Prince of Wales used to give himself an illicit thrill on a weekday afternoon by watching the women's riding-school in the Royal Albert Hall.Re:cyclists looks at how cycling became the sport, the pastime and the social life of millions of ordinary people, how it grew and how it suffered through the 1960s and '70s, and how at the dawn of the twenty-first century it rose again, much changed but still ultimately just someone careering along on two wheels.

    He was a celebrity during the height of America’s Gilded Age. In this book, you will read about his friendship with Mark Twain, his furious competition with his former employer Thomas Edison, his uneasy relationship with billionaire J.P. Morgan, and his rivalry with Albert Einstein. During his lifetime, Tesla revolutionized the field of electrical engineering with his most famous invention: the induction motor. But that wasn’t all he contributed to the world of technology. His coils, turbines, robotic boats, and mysterious “death ray” continue to beguile the imagination and inspire the inventors of the 21st century. But who was Tesla really? This book will take you from his early childhood in Croatia, where he experienced strange optical visions and “luminous phenomenon” that gave him near super-human powers of memory and visualization, to the “War of the Currents”, Thomas Edison’s bizarre campaign to ruin Tesla’s reputation. From trying to fight the Spanish American War with robots, to electrifying the skies of the Colorado desert, and to starting an earthquake in the middle of New York city, learn how Nikola Tesla shaped the world we live in today.

    Why does music evoke such powerful moods? The answers are at last be- coming clear, thanks to revolutionary neuroscience and the emerging field of evolutionary psychology. Both a cutting-edge study and a tribute to the beauty of music itself, This Is Your Brain on Music unravels a host of mysteries that affect everything from pop culture to our understanding of human nature, including: • Are our musical preferences shaped in utero? • Is there a cutoff point for acquiring new tastes in music? • What do PET scans and MRIs reveal about the brain’s response to music? • Is musical pleasure different from other kinds of pleasure?This Is Your Brain on Music explores cultures in which singing is considered an essential human function, patients who have a rare disorder that prevents them from making sense of music, and scientists studying why two people may not have the same definition of pitch. At every turn, this provocative work unlocks deep secrets about how nature and nurture forge a uniquely human obsession.

    Nancy Butcher has gathered together some of the most unusual natural cures that have been proven effective today, and even throws in some unbelievable and-thankfully-abandoned therapies from times past.Filled with case histories of unique illnesses, historic documentation of strange medical practices, and the author's own insightful commentary, this book explains not only how to cure headaches, sleep better, and improve your sex life, but also that people with Cotard's syndrome actually believe they are dead.

    For millions, the Galápagos Islands represent nature at its most unspoiled, an inviolate place famed for its rare flora and fauna. But soon today’s 30,000 human residents could surpass 50,000. Add invasive species, floods of tourists, and unresolved conflicts between Ecuadorian laws and local concerns, and it’s easy to see why the Galápagos were recently added to UNESCO’s World Heritage in Danger list. Each chapter in this provocative, perceptive book focuses on a specific person or group with a stake in the Galápagos’ natural resources—from tour companies whose activities are often illegal and not always green, to creationist guides who lead tours with no mention of evolution, from fishermen up in arms over lobster quotas, to modern-day pirates who poach endangered marine species. Bassett presents a perspective as readable as it is sensible. Told with wit, passion, and grace, the Galápagos story serves as a miniature model of Earth itself, a perfect example of how an environment can be destroyed-- and what is being done to preserve these islands before it's too late.

    Now he gathers the best of his best, updated and expanded upon, to guide readers on a mind-bending tour of the far frontier, and how these advances are radically transforming our lives. From the ways science and technology are fundamentally altering our bodies and our world (the world’s first bionic soldier, the future of evolution) to those explosive collisions between science and culture (life extension and bioweapons), we’re crossing moral and ethical lines we’ve never faced before.As Kotler writes, “Life is tricky sport—and that's the emotional core of this story, the real reason we can’t put Pandora back in the box. When you strip everything else away, technology is nothing more than the promise of an easier tomorrow. It’s the promise of hope. And how do you stop hope?”Join Kotler in this fascinating exploration of our incredible next: a deep dive into those future technologies happening now—and what it means to be a part of this brave new world.
