Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

Throughout our life, we look for ways to keep our minds sharp and effortlessly productive. Now, globetrotting neurosurgeon Dr. Sanjay Gupta offers “the book all of us need, young and old” (Walter Isaacson, number-one New York Times best-selling author of The Code Breaker) with insights from top scientists all over the world, whose cutting-edge research can help you heighten and protect brain function and maintain cognitive health at any age.

Did you know you can beat stress, lift your mood, fight memory loss, sharpen your intellect, and function better than ever simply by elevating your heart rate and breaking a sweat? The evidence is incontrovertible: Aerobic exercise physically remodels our brains for peak performance. In Spark, John J. Ratey, MD, embarks upon a fascinating and entertaining journey through the mind-body connection, presenting startling research to prove that exercise is truly our best defense against everything from depression to ADD to addiction to aggression to menopause to Alzheimer's.

When high speed Internet became widely available a few years ago, growing numbers of people began to worry that their porn use was running out of control. Far from preparing them for fulfilling relationships, viewing an endless stream of porn videos led to unexpected symptoms.

Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer.

A true scientific pause-resister that traces a remarkable scientific breakthrough (the isolation of endorphins in the brain) as dedicated scientists race - not only with their fellow scientists - but against time and the profit hungry giant pharmaceutical companies. This audiobook chronicles the fascinating discovery of endorphins, the body's natural painkiller.

While researching the toxic and addictive properties of sugar for Fat Chance, Robert Lustig made an alarming discovery - our pursuit of happiness is being subverted by a culture of addiction and depression from which we may never recover. Dopamine is the "reward" neurotransmitter that tells our brains we want more; yet every substance or behavior that releases dopamine in the extreme leads to addiction. Serotonin is the "contentment" neurotransmitter that tells our brains we don't need any more; yet its deficiency leads to depression.

Challenging both the idea of the addict's "broken brain" and the notion of a simple "addictive personality", Unbroken Brain offers a radical and groundbreaking new perspective, arguing that addiction is a learning disorder, and shows how seeing the condition this way can untangle our current debates over treatment, prevention, and policy.

Have you wondered why some 60-year-olds look and feel like 40-year-olds and why some 40-year-olds look and feel like 60-year-olds? While many factors contribute to aging and illness, Dr. Elizabeth Blackburn discovered a biological indicator called telomerase, the enzyme that replenishes telomeres, which protect our genetic heritage. Dr. Blackburn and Dr. Elissa Epel's research shows that the length and health of one's telomeres are a biological underpinning of the long-hypothesized mind-body connection.
