Hurt people hurt people.Say there was a novel in which Holden Caulfield was an alcoholic and Lolita was a photographer's assistant and, somehow, they met in Bright Lights, Big City. He's blinded by love. She by ambition. Diary of an Oxygen Thief is an honest, hilarious, and heartrending novel, but above all, a very realistic account of what we do to each other and what we allow to have done to us.

The remarkable scientific story of how Earth became an oxygenated planetThe air we breathe is twenty-one percent oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it come to be this way? Donald Canfield covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of Earth. He guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field. Now with an incisive new preface by the author, Oxygen takes readers on an astonishing journey of discovery, telling the story of how our planet became oxygenated.

Improve your body’s oxygen use and increase your health, weight loss, and sports performance—whether you’re a recovering couch potato or an Ironman triathlon champion.

One of the biggest obstacles to better health and fitness is a rarely identified problem: chronic over-breathing. We often take many more breaths than we need—without realizing it—contributing to poor health and fitness, including a host of disorders, from anxiety and asthma to insomnia and heart problems.

In The Oxygen Advantage, the man who has trained over 5,000 people—including Olympic and professional athletes—in reduced breathing exercises now shares his scientifically validated techniques to help you breathe more efficiently. Patrick McKeown teaches you the fundamental relationship between oxygen and the body, then gets you started with a Body Oxygen Level Test (BOLT) to determine how efficiently your body uses oxygen. He then shows you how to increase your BOLT score by using light breathing exercises and learning how to simulate high altitude training, a technique used by Navy SEALs and professional athletes to help increase endurance, weight loss, and vital red blood cells to dramatically improve cardio-fitness.

Following his program, even the most out-of-shape person (including those with chronic respiratory conditions such as asthma) can climb stairs, run for a bus, or play soccer without gasping for air, and everyone can achieve:

Easy weight loss and weight maintenanceImproved sleep and energyIncreased concentrationReduced breathlessness during exerciseHeightened athletic performanceImproved cardiovascular healthElimination of asthmatic symptoms, and more.

With The Oxygen Advantage, you can look better, feel better, and do more—it’s as easy as breathing.

The Best-Kept Secret in MedicineIn the United States, the FDA currently recognizes hyperbaric oxygen therapy (HBOT) for 14 conditions, including decompression sickness, embolism, crush injury, bone infection, burns, wound healing, severe anemia, and several others.Now, in The Oxygen Cure, hyperbaric expert William S. Maxfield, M.D., will convince you that HBOT is a vastly underused modality that deserves to take its place among frontline medical treatments. As a holistic treatment, HBOT targets the underlying disease or condition, not just the symptoms.The Oxygen Cure reveals how hundreds of studies on HBOT conducted around the world prove it works at the cellular level to help or heal conditions such as:StrokeChemo-Related Side EffectsEpilepsyFibromyalgiaEmphysema & AsthmaADHDRheumatoid ArthritisCardiac DiseasesMigraine & VertigoEarly DementiaVision LossMultiple Sclerosis & Parkinson's DiseaseTraumatic Brain Injury & PTSDAnd Dozens MoreFull of hope-inspiring case histories and expert findings, The Oxygen Cure shows how HBOT not only benefits the sick and injured (including our wounded veterans), but may also reduce our country’s staggeringly high medical costs.HBOT often provides a safe alternative to drug therapy and dangerous invasive procedures.

This unique work from acclaimed author Dr. Paul Marino (Marino’s The ICU Book, The Little ICU Book) challenges the traditional notion that the human body thrives on oxygen, and that promoting tissue oxygenation is necessary for promoting life. This concept fails to recognize that oxygen is a destructive molecule that also damages the human body.  Instead of welcoming oxygen, the human body limits exposure of the tissues to oxygen, and employs an army of chemical antioxidants to combat the damaging effects of oxygen.  This “oxygen protective” human design represents a new paradigm for the relationship between oxygen and human survival, and it has important implications for the excessive and unregulated use of oxygen in clinical practice. Dr. Marino’s book includes the following  relevant features: Describes how oxygen and its reactive derivatives can damage vital cell components, and how oxygen plays a pivotal role in the damaging effects of inflammation, radiation, and aging.Challenges the traditional notion that oxygen delivery is the principal function of the cardiorespiratory system, and that oxygen transport is the principal function of red blood cells and hemoglobin.Demonstrates how the tissues normally operate in an oxygen-poor environment (which limits the risk of oxidative damage), and how the body counteracts attempts to increase tissue oxygenation.Describes the body’s use of protective antioxidants, and shows how failure to maintain this antioxidant protection makes oxygen inhalation an unrecognized source of harm.Reveals the lack of evidence that cellular hypoxia is a final common pathway for cell death, and proposes that oxygen itself is responsible for the death of aerobic organisms.Proposes a new management strategy that is “oxygen-protective” rather than “oxygen-promoting.”Enrich Your eBook Reading ExperienceRead directly on your preferred device(s), such as computer, tablet, or smartphone.Easily convert to audiobook, powering your content with natural language text-to-speech.

Oxygen has had extraordinary effects on life. Three hundred million years ago, in Carboniferous times, dragonflies grew as big as seagulls, with wingspans ofnearly a metre. Researchers claim they could have flown only if the air had contained more oxygen than today -probably as much as 35 per cent. Giant spiders, tree-ferns, marine rock formations and fossil charcoalsall tell the same story. High oxygen levels may also explain the global firestorm that contributed to thedemise of the dinosaurs after the asteroid impact. The strange and profound effects that oxygen has had on the evolution of life pose a riddle, which this booksets out to answer. Oxygen is a toxic gas. Divers breathing pure oxygen at depth suffer from convulsionsand lung injury. Fruit flies raised at twice normal atmospheric levels of oxygen live half as long as theirsiblings. Reactive forms of oxygen, known as free radicals, are thought to cause ageing in people. Yet ifatmospheric oxygen reached 35 per cent in the Carboniferous, why did it promote exuberant growth,instead of rapid ageing and death? Oxygen takes the reader on an enthralling journey, as gripping as a thriller, as it unravels the unexpectedways in which oxygen spurred the evolution of life and death. The book explains far more than the size ofancient insects: it shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the sudden evolution of animals, the need for two sexes, the accelerated ageing of cloned animals like Dolly the sheep, and the surprisingly long lives of bats and birds. Drawing on this grand evolutionary canvas, Oxygen offers fresh perspectives on our own lives and deaths,explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas,following chains of evidence, the book ranges through many disciplines, from environmental sciences tomolecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of ourplace in nature. This remarkable book will redefine the way we think about the world.
