In industrialised nations, our sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases like diabetes. A key remedy, we are told, is exercise - voluntary physical activity for the sake of health. However, most of us struggle to stay fit, and our attitudes to exercise are plagued by misconceptions, finger-pointing and anxiety. But, as Daniel Lieberman shows in Exercised, the first book of its kind by a leading scientific expert, we never evolved to exercise.

In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and more.

The conscious mind, the part of your mental life you experience directly, is responsible for only a tiny sliver of what science says is going on inside your brain. Most of what you experience, your moods, and the things you like or dislike—most of who you are—comes from a much more mysterious part of your mind: the unconscious. And to really understand the influences of the unconscious, says psychiatrist Daniel Z. Liberman, coauthor of The Molecule of More, we need to look to something often considered science’s alter ego: magic.

In this landmark book of popular science, Daniel E. Lieberman - chair of the department of human evolutionary biology at Harvard University and a leader in the field - gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease.

A dopamina é o neurotransmissor que garantiu a sobrevivência dos nossos antepassados e que, ainda hoje, continua determinando a maioria dos nossos comportamentos. Graças a ela fomos à Lua, encontramos a cura de várias doenças e nos esforçamos para transformar o mundo em um lugar melhor. Mas ela também nos torna suscetíveis a arriscar nosso casamento por uma aventura passageira e é capaz de explicar por que o dependente químico está disposto a fazer qualquer coisa pela próxima dose.

Warum wollen wir wie besessen bestimmte Dinge haben, sind aber gelangweilt, wenn wir sie bekommen? Warum verwandelt sich die Leidenschaft von Verliebten so schnell in Desinteresse? Die Antwort liegt in einem Hormon in unserem Gehirn: Dopamin. Es ist die Quelle unseres Verlangens und lässt uns für einen kurzen Nervenkitzel alles riskieren. Dabei ist es die Aussicht auf etwas Neues, die uns antreibt, nicht die Erfüllung. Dopamin ist der Grund, warum wir forschen und entdecken, aber auch der Ursprung von Verschwendung, Risiko und Sucht.
