'An exquisite book that reminds us our minds aren't soloists but symphony players: we are wired for connection.'."-David Eagleman, PhD, author of Incognito and Livewired 'A must-read for anyone who wants to feel better and live longer, one conversation at a time!' - Dr. Karan Rajan, author of This Book May Save Your Life From your morning coffee order, to weaving through passengers on the train, sitting through tense work meetings, riding in a packed elevator, attending a happy hour with colleagues, or relaxing on the couch with family, every day is filled with social interactions that nurture and support your brain's health. Whether mundane or extraordinary, they collectively make up the 'social diet' that you feed your brain, that influences your well-being, shapes your experience, and, done right, even lengthens your life. In an age of isolation, WHY BRAINS NEED FRIENDS is a neuroscience-backed guide to social interactions, drawing insights from the world of science to help you understand the biology behind your relationships, reconsider the value of companionship, and build a healthier, happier, and more connected life. It's not just what you feed your brain that matters - it's who.
