Can you tell who's up for it?
Updated on 09 April 2008
Two of the faces above are up for casual sex, the other two want a long-term relationship. Can you tell which is which?
According to researchers from Durham University, you should be able to.
They say their research shows that we can tell people's attitudes towards sex, just from their facial features.
They say: "Men generally prefer women who they perceive are open to short-term sexual relationships whilst women are usually interested in men who appear to have potential to be long-term relationship material."
The faces are composite pictures of faces belonging to those who said either that they were - or weren't - up for casual sex.
What do you think?
Take a good look at the image below.
Which do you think is which - and which do you prefer? Of the female faces, do you think A or B is more interested in a short-term sexual relationship. And which of the male faces - C or D - do you think fits with someone up for casual sex?
Why? Or do you think the whole idea is ridiculous?
