The chemistry between us : love, sex, and the science of attraction

Since the dawn of humanity we've been mystified by desire, love, and the compulsion to bond with others.

How do we fall in love and back out again? Why do people differ and how and who they love? What force keeps people together, and, if it's so powerful, how can anybody ever cheat?

Neuroscientists like Young are at last able to peer inside living brains to discover how chemicals acting on circuits drive such seemingly complex behaviours.

It turns out that on a molecular level, love is not so mysterious after all.
