“老牛吃嫩草”，只会让你显得更老

According to the Daily Telegraph on January 7, marrying someone much younger only makes you seem older in the eyes of everyone else, shows an academic study.

据英国《每日电讯报》1月7日报道，一项科学研究显示，和比自己年轻很多的人结婚，只会让你在别人眼里显得更老。

When someone see a mature man with a woman half his age, they estimate him to be much older than it really is because of the obvious gap, said the study.

研究表明，当人们看到一个成熟的男人和年龄比他小一半的女性在一起时，因为年龄差距较大，这个男人往往要显得比实际年龄更大一些。

Psychologists from Jena University in Germany discovered that a person's perceived age varies depending on the people they are with.

德国耶拿大学的心理学家发现，人们的外表年龄往往随着身边的人有所变化。

They carried out a series of research projects called Person Perception to see how people estimate the age of others.

研究人员进行了一系列“年龄直觉”的研究项目，观察人们如何判断其他人的年龄。

If they see a person on their own then most observers are fairly good as estimating that person's age. And the same applies if there is a group where everyone is around the same age.

如果被调查者是单独一人，大部分观察者都能相对准确地猜测出他的年龄。如果一个小组的成员年龄相仿，这一原理同样适用。

But if most of a group are old and one person is young, that difference is exaggerated and those trying to guess the individual's age are "consistently wrong" said the research.

但是，研究显示如果一个小组大部分成员都比较年长，而一个人较年轻，年龄猜测的准确率明显下降。猜测者估计的年龄要和被猜测者的实际年龄"相差万里"。
