Humans are social creatures: In this simple and obvious fact lies both the problem and the solution to the current crisis of loneliness. In his groundbreaking book, the 19th surgeon general of the United States Dr. Vivek Murthy makes a case for loneliness as a public health concern: a root cause and contributor to many of the epidemics sweeping the world today from alcohol and drug addiction to violence to depression and anxiety. Loneliness, he argues, is affecting not only our health, but also how our children experience school, how we perform in the workplace, and the sense of division and polarization in our society.
