Lucy Vincent doctorate in neuroscience, so what happens in the brain knows it. The book describes the state of love not as we know it (and described in fairy accounts), but from a scientific point of view: the brain in love !! Chemical Exchanges, the result of scientific studies, what we're looking at each other, why we made to each other or not ... And it comes to surprising conclusions which can only interest us on this subject ( this is an innate sense in humans is not it?). For example: Scientists are categorical: The characteristics of being in love ... has a deadline! Disrupts received ideas and is powerful! It is well written, easy to read, punctuated with many experiences, also addresses psychological issues for a successful couple trying to understand what makes it work or not ... love does not lose any provided its magical side, but personally, this book gave me many tips to improve my relationship. I advise everyone this book especially to people like me, began to ask other questions as "Ben Love, it is love, it is not explained." Think again, it is explained! A must have!
