Flirting is a fundamental fixture in the sexual behavior repertoire, a time-honored way of signaling interest and attraction, to say nothing of mutual awareness. It is a kind of silent language spoken by men and women around the world.
The ways people communicate interest are so deeply rooted in human nature that the signals are automatically understood by all. All humans come equipped with the language of flirtation, from ways of glancing to movements such as licking one's lips, to meet nature's most basic command—find a good mate and multiply.
Flirting is not a trivial activity; it requires many skills: intellect, body language, creativity, empathy. At its best, flirting can be high art, whether the flirter is vying for a soul mate, manipulating a potential customer, or just being playful.
The process of flirting allows the signaling of interest to another in small increments, which is especially appealing to a partner and enables both parties to gauge the interest level of the other. Flirting is driven by emotions and instinct rather than logical thought. Yet there is profound information transmitted in flirting—the gestures and movements used in flirting provide reliable clues to a person's biological and psychological health.
