Sleep is one of the most important but least understood aspects of our lives. It affects our wellness and longevity, and yet questions about why we sleep and its purpose have only recently been answered.

Neuroscientist and sleep expert Matt Walker provides a new understanding of sleep and how it affects our ability to learn, memorize and make logical decisions. Walker also answers a variety of questions about dreaming, sleep patterns, aging and disease prevention.
