The Power of Scent

A favorable scent goes a long way. Want to boost your mood or stir up old memories? Try using your nose. And, most important, scent can even drive one to romantic distraction. Just think about your partner's pajamas. Indeed, the nose can even suss out the complex, like sexual compatibility. We have more than 100 immune system genes known as the MHC, or major histocompatibility complex; these genes help our immune system suss out pathogens. The MHC also influences us in our mating choices. Just think about the dirty T-shirt experiments, and why certain people are drawn to certain smells and odors.
