It's the first sense that's activated when we're born. It can instantly transport you back to your grandmother's kitchen or an ex-lover's embrace. Smell is provocative and deeply connected to our emotional state—and it has a far greater influence on our behavior than we realize.
A favorable scent goes a long way. Want to boost your mood or stir up old memories? Just use your nose. And, most important, scent can even drive one to romantic distraction. Think of your partner's pajamas.
