With The World Book of Happiness Leo Bormans launched a unique international project and a movement for happiness. After the succes of this book (+200,000 copies sold) he spent two years studying the scientific research on love, gathering insights from the greatest experts. In this book, 100 researchers from 50 countries summarize in 1000 words their particular views on love. The result is a kaleidoscopic work full of wisdom and insight into the system and the mystery of love. The World Book of Love is all about attachment, passion and devotion, jealousy and abuse, Darwin, speed dates and brain scans. It's about parental love, friends, sex, marriage and divorce, butterflies in the stomach and elderly care. But above all it is a book about the secret of romantic love. In a globalized world we can all learn from each other.
