Using his own research and experiences throughout the world, Lieberman recounts without jargon how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion.Exercised is entertaining and enlightening but also constructive. As our increasingly sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases such as diabetes, Lieberman audaciously argues that to become more active we need to do more than medicalize and commodify exercise.Drawing on insights from evolutionary biology and anthropology, Lieberman suggests how we can make exercise more enjoyable, rather than shaming and blaming people for avoiding it. He also tackles the question of whether you can exercise too much, even as he explains why exercise can reduce our vulnerability to the diseases mostly likely to make us sick and kill us.

    Based in the latest research in neuroscience, this audiobook offers dozens of little things you can do every day to rewire your brain and create an upward spiral towards a happier, healthier life.Depression doesn't happen all at once. It starts gradually and builds momentum over time. If you go through a difficult experience, you may stop taking care of yourself. You may stop exercising and eating healthy, which will end up making you feel even worse as time goes on. You are caught in a downward spiral, but you may feel too tired, too overwhelmed, and too scared to try and pull yourself back up. The good news is that just one small step can be a step in the right direction.In The Upward Spiral, neuroscientist Alex Korb demystifies the neurological processes in the brain that cause depression and offers effective ways to get better "one little step at a time". In the book, you'll discover that there isn't "one big solution" that will solve your depression. Instead, there are dozens of small, practical things you can do to alleviate your symptoms and start healing. Some are as simple as relaxing certain muscles to reduce feelings of anxiety, while others involve making small efforts toward more positive social interactions. Small steps in the right direction can have profound effects giving you the power to literally "reshape" your brain.Like most people, you probably didn't wake up one day and find yourself completely depressed. Instead, it probably happened over time, as a series of reactions to difficult situations and negative thinking. But if you are ready to reverse the trajectory of your depression and find lasting happiness, this book will show you how.

    In college, I ran against Kenyans, and wondered whether endurance genes might have traveled with them from East Africa. At the same time, I began to notice that a training group on my team could consist of five men who run next to one another, stride for stride, day after day, and nonetheless turn out five entirely different runners. How could this be?We all knew a star athlete in high school. The one who made it look so easy. He was the starting quarterback and shortstop; she was the all-state point guard and high-jumper. Naturals. Or were they?The debate is as old as physical competition. Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training?The truth is far messier than a simple dichotomy between nature and nurture. In the decade since the sequencing of the human genome, researchers have slowly begun to uncover how the relationship between biological endowments and a competitor’s training environment affects athleticism. Sports scientists have gradually entered the era of modern genetic research.In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle. He investigates the so-called 10,000-hour rule to uncover whether rigorous and consistent practice from a young age is the only route to athletic excellence.Along the way, Epstein dispels many of our perceptions about why top athletes excel. He shows why some skills that we assume are innate, like the bullet-fast reactions of a baseball or cricket batter, are not, and why other characteristics that we assume are entirely voluntary, like an athlete’s will to train, might in fact have important genetic components.This subject necessarily involves digging deep into sensitive topics like race and gender. Epstein explores controversial questions such as:Are black athletes genetically predetermined to dominate both sprinting and distance running, and are their abilities influenced by Africa’s geography?Are there genetic reasons to separate male and female athletes in competition?Should we test the genes of young children to determine if they are destined for stardom?Can genetic testing determine who is at risk of injury, brain damage, or even death on the field?Through on-the-ground reporting from below the equator and above the Arctic Circle, revealing conversations with leading scientists and Olympic champions, and interviews with athletes who have rare genetic mutations or physical traits, Epstein forces us to rethink the very nature of athleticism.
