Members of the opposite sex can spot whether someone is after a one-night stand or something more permanent just by looking at their face, scientists said on Wednesday.
On men, a square jaw, large nose and small eyes are more likely to betray the look of lust than of love.
Women found men with softer features more likely to opt for commitment.
But the Durham University-led research found that while men can judge whether a woman is footloose-and-fancy-free or not, there is no common facial detail to explain it.
