Transformer in chief: the newest member of the c-suite - Raconteur

It may be telling that one of the smash hit books of the past year has been on sleep. Berkeley professor of neuroscience Matthew Walker's Why We Sleep was a comprehensive analysis of why humans need to sleep, which doubled up as a polemic against the habits that lead to insomnia. He marvels: "A hundred years ago, less than 2 per cent of the population in the United States slept six hours or less a night. Now, almost 30 per cent of American adults do." The health implications are shocking. Lack of sleep leads to mental illness, diabetes and chaos.
