“A lot of people head into courtship looking for fireworks. Don't pass up a chance by dumping someone after a first date because you don't feel the fireworks. The fireworks can happen at any time and be maintained.”

American anthropologist and research fellow at the Kinsey Institute, Helen Fisher is best known for her work on human mating patterns and the science of romantic love. Her studies explore how biology influences attraction, relationships, and even cultural differences in love.
