The brains of world-class performers are different from the brains of average performers. No surprise there. But what is surprising is that regardless of whether these top performers are athletes, musicians, or CEOs, their brains share one feature that makes them stand out: more integrated functioning. A world-class brain works in a more coherent, relaxed, wakeful, and efficient way. World-Class Brain tells the story of these top performers and offers an easy-to-read introduction to the research showing that their brain function is different. This short book also describes other features that these top performers have in common, such as intensely happy and fulfilling peak experiences and a greater moral sense. Readers also learn how they, too, can effortlessly develop greater brain integration.
