What if society wasn't fundamentally rational, but was motivated by insanity? This thought sets Jon Ronson on an utterly compelling adventure into the world of madness.

Along the way, Jon meets psychopaths, those whose lives have been touched by madness and those whose job it is to diagnose it, including the influential psychologist who developed the Psychopath Test, from whom Jon learns the art of psychopath-spotting. A skill which seemingly reveals that madness could indeed be at the heart of everything . . .

Combining Jon Ronson's trademark humour, charm and investigative incision, The Psychopath Test is both entertaining and honest, unearthing dangerous truths and asking serious questions about how we define normality in a world where we are increasingly judged by our maddest edges.

Does the thought of delivering a presentation make your heart skip a beat? Do your pitches fall flat no matter how much preparation you put in? Are you often comparing yourself to more eloquent speakers and wondering how they capture the room?

At some point in our careers we will need to speak in front of an audience; whether to present our ideas to a group of five in a meeting, pitch for investment in front of a panel or deliver a keynote speech to one thousand delegates. Yet glossophobia, or the fear of public speaking, is incredibly common and can inhibit our chances of career progression by up to 15%.

In Speaking with Confidence, Expert and managing director of Speakers' Corner Nick Gold, shows how anyone can learn to be a confident public speaker and use their surroundings to give them the support and structure they need to achieve maximum impact and success from their speech. His decades of experience coaching and producing some of the best speakers in the country have been condensed here into one expert guide to help you connect with your audience every time.

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.

In this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves into everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.
