The way we live now has its roots much further back in history. Do you ever wonder how we came to have seven days in a week, and when we divided off two as the weekend? Why some countries drive on the right and others on the left? When we first started to use spectacles, or plant gardens for pleasure, not just for food? Or why Christians, Jews and Muslims all regard Jerusalem as a holy city? Over eight themed chapters, How it all started takes these and more than 150 similarly intriguing questions about familiar aspects of our daily lives and traces the complex political, social, religious and cultural factors that have shaped our modern world.
