What to do: Hold out your right hand, keeping your fingers together. Compare the length of your first (or index) finger, with your third (ring) finger, from the tip to the crease where it is attached to the hand.

What it means: The relative size of your fingers is strongly linked to your exposure to the male sex hormone testosterone in the womb. Babies exposed to higher levels tend to grow longer ring fingers.

Because testosterone is also linked to ‘masculine’ traits — such as assertiveness, aggression and sex drive — finger length sheds light on a host of personality traits.

If a man’s ring finger is the same length, or shorter than, his index finger, he tends to be less aggressive, less competitive and nicer to women, studies have shown.

If it is longer, then he will be more assertive, more likely to take risks and more likely to be promiscuous.

Most women’s index and ring fingers are almost equal in length. However, if their ring ringers are longer, they tend to be more assertive and are more likely to run successful businesses, scientists say.
