BBC NEWS Health Women 'sense qualities in a man'
"Women are fine tuned subconsciously to detect the qualities they are looking for in a man - just by looking at his face, US research suggests.
Women can spot subtle signs of interest in children in a man's face, and accurately assess his level of the sex hormone testosterone, it claims.
Child-friendly men were rated as good long-term bets, masculine men as ideal for a more short-term fling. "

Interesting. Makes me wonder at some of the couples I do know about that really shouldn't be together.
