...human behavior is very subtle, three women from three different generations, Arianna Huffington (age 64), and Rosario Dawson (age 35).
Without getting too deep for the Coli, wide eyes, strong cheek structure and full lips signals "fertility" to a man. Dawson's chin is untucked, and she's exposing her breast. Her body is releasing pheromones unknowingly. In today's society, we've learned to hide our primal instinct, with contrived social cues, sometimes verbally like a "laugh" to deflect we're sexually uncomfortable. However,look at Huffington, who is a parent, smaller lips, tucked chin, and squinting eyes shows that she's concentrating and not thinking about sex. She's comfortable.
Look at Clooney, direct eye contact with his body angled towards his most viable candidate for insemination.
His eyes are squinting, as he mimics her smile, focusing in on her, in reaction to her eyebrows because they arch high when females are ovulating because of the rush of estrogen .
It's no coincidence that neither of them have children, and are sexually attracted to each other...it's biology at its finest moment. Body language does not lie to the trained eye.
