Tell Me How You're Sleeping. A survey of the sleep patterns of 12,000 people

How do we sleep? The same or differently? Do we sleep too much or not enough? Whose sleep is "normal" and whose is "abnormal"? What's an insomniac? How many insomniacs are there? How many people use drugs to help them sleep? And do we sleep differently according to our lifestyle, our age, our social status, our cultural habits, or where we live? These are all questions that lie behind this book. Why? Because without the answers to these questions, our understanding of sleep has previously been incomplete. When people are asked about the way they sleep, it is usually in a clinical context, under medical supervision. But what are the characteristics of sleep in the general population? How does the 1919 "normal" individual experience sleep?
