This fascinating review of what social psychologists know about love, sex and intimacy puts to rest some tired cliches on the subject. Begins by asking What is this thing called love? and finds that people distinguish between two kinds of love, passionate love and companionate love. This study answers a variety of questions about love such as: Where is the best place to find someone to love? Do men and women want different things from love? How can couples make love last?
