Flutter those lashes, girl

A German scientist, Irenäus Eibl-Eibesfeldt, once studied women’s flirting behavior and
found that nearly all women make the same facial movements when they flirt, in the exact same order. They

1. Smile.
2. Lift their eyebrows in a fast, jerky motion.
3. Open their eyes wide (a sign of sympathetic system arousal, which means that the “Hey, pay attention!” part of our nervous system has kicked into gear).
4. Lower their eyelids.
5. Tilt their heads down and to the side (a universal sign of submission in the animal kingdom).
6. Look away.

Sound like anyone you know? These flirting gestures are so universal that Eibl-Eibesfeldt believes they’re innate sexual signals evolved from the beginning of human history.
