She nose a good man when she smells him
Online chat isn't only a great tool for meeting potential dates, it is also a platform for meeting great friends.
So what is the deal when you meet your platonic online chat buddy in person and then find yourself falling for him?
Researchers claim you should blame (or thank) your nose for this surprise attraction.
A Prague study found that dominant guys smell more attractive to women, and that women subconsciously prefer the smell of dominant males when they are at the peak of their menstrual cycle.
During the study, smell samples of 48 guys were presented to 65 women, and women who were ovulating rated the 'dominant' men as the sexiest.
Researcher Dr Craig Roberts commented: "There seems to be some sort of physiological mechanism that directs women to indicators of good genes.
"The offspring of such a coupling would therefore be likely to have better genes," he told the BBC News website.
