Study reveals how to identify the look of love - or lust

Facial features can be clues as to whether a member of the opposite sex is after a one-night stand or something more permanent, scientists say.

On men, a square jaw, large nose and small eyes are more likely to betray the look of lust than of love. On women, the give-away features tend to be wide eyes and large lips, a la Angelina Jolie. The Durham University-led research said women found men with softer features more likely to opt for commitment.

But while men can judge whether a woman is footloose-and-fancy-free, there was no common facial detail to explain it.
