By comparing your index and ring fingers, a neuroscientist can tell if you are likely to be anxious or whether you are likely to be a good athlete.

比较下你的食指和无名指，神经科学家便可知，你是更容易焦虑还是更容易成为优秀运动员。

If your index finger is longer than your ring finger, you are likely to be bad at sports but better at verbal memory tasks, a new study says.

一项新研究称，你的食指若是比无名指长，你有可能运动不佳，但语言记忆类任务会完成得更好。

But men and women with shorter index fingers compared to their ring finger are less anxious, better at mentally demanding 3D-rotation tasks and better at sport.

但食指比无名指短些的男性和女性不那么焦虑，更擅长挑战头脑的3D旋转任务，运动也更好。

Scientists have long known adults whose index finger is shorter than their ring finger are exposed to greater amounts of testosterone when they were in the womb.

科学家们一直就知道食指比无名指短的成人，在子宫里的睾丸素水平高。

The ratio between the ring and index fingers, known in scientists’ jargon as 2D and 4D, can reveal the levels of testosterone someone was exposed to in the womb.

食指和无名指的比例，用科学家的术语来说，就是2D和4D，可以显示出在子宫内的睾丸素水平。

The greater level of testosterone means someone is likely to be a better athlete.

睾丸素水平越高，意味着更可能成为优秀运动员。

But low levels of testosterone are associated with better abilities in verbal memory tasks, like remembering lists of words.

但睾丸素水平低的人语言记忆能力更好，如记忆单词列表。

But, those who do not fall into either of these categories, with index and ring fingers the same length, are more likely to be faithful, according to a study last year.

但去年一项研究称，对于那些两种类别都不从属的人而言，食指和无名指长度一样，更可能保持忠诚。
