Forget witty¹ chat-up lines and splashing on the aftershave. It appears the secret of a man’s attractiveness to the opposite sex lies in his hands.

忘了那些风趣的搭讪和须后水吧，看来男人对异性吸引力的秘诀在于他的手中。

Men whose ring fingers are longer than their index fingers（食指） are seen as better bets by women, a study found. By contrast those seen as wimpier sorts will have longer index fingers.

It is thought that exposure to high levels of testosterone（睾丸素） in the womb has a long-lasting effect on finger-length – and on looks.

The study is the latest in a long line to link the shape of man’s hands with his path in life.

British, French and Swiss researchers photographed 49 young men and measured the length of their ring and index fingers.

They also recorded their voices and took swabs（棉签） to capture general odour（气味） . They then showed a group of women the photos and asked them to rate the men’s looks.

Those whose ring fingers were longer than their index fingers were more likely to win the women’s approval. They were seen as good prospects² for both a fling and a long-term relationship.

However, they scored no more highly than the other men in terms of having a sexy voice or ‘attractive’ body odour, the journal Proceedings³ of the Royal Society reports.

Stirling University researcher Craig Roberts said exposure to testosterone in the womb likely affects facial structure as well as finger length. Having a long ring finger confers a host of other benefits. For instance, scientists believe the longer a man’s ring finger is compared to his index finger, the richer he is likely to be.

They claim he is also likely to be a promiscuous⁴（混杂的） , extroverted⁵ go-getter with strong muscles and has a greater likelihood of playing a musical instrument.

Unfortunately such men also have a higher chance of ending up in prison, being murdered or going mad.
