Love is wild, wonderful, irrational and passionate. This book is a collection of creative essays that combine a mix of science, psychology, personal insight and passionate stories focused on the chemistry of lasting love. The authors explore a wealth of topics on the subject including the difference between falling and staying in love; the nature of soul mates; how men and women express their love differently; the creation of meaning in relationships; the role of passion and libido and much more. Best-selling experts, marital therapists and researchers explore the powerful underlying emotion that binds couples together - for better or for worse. Celebrity couples - Christopher Reeve and Dana Morosine, Warren Beatty and Annette Bening, George and Barbara Bush - and others are quoted for their own words of wisdom.
