  Destiny's child?

  命运的产物?

  Those who believe in progress will, however, be pleased to know that epigenetics is not necessarily destiny. Methyl groups may help maintain the status quo, but if that status quo is interrupted by outside events they can be wiped away and a new lot put in place.

  但是,相信事物是发展变化的人们会很高兴,因为表现遗传学并不是上天注定,难以改变的。甲基或许可以帮助维持现状,但是如果外来事件打断了它,那么甲基将被移除,新的一批上任。

  

  Dr Tung and Dr Gilad discovered this because a few of their monkeys did change status within their groups. When that happened, changes in gene expression appropriate to the new status quickly followed. Those who do break free from their lowly station, then, may begin to reap the health benefits almost immediately.

  博士东和吉拉德能够发现了这一点,是因为,参与实验的几个猴子确实改变了她们在群体中的地位等级。地位等级一旦发生改变,与之相应的基因表达随即改变。那些确实改变了它们之前卑贱地位的猴子们,身体状况几乎都立刻获得改善。

  As with any animal study, this one cannot simply be mapped straight onto humans. But it does provide pointers that researchers who work on people can use.

  不管以什么动物为研究对象,结果都不能直接简单地运用于人类,这个也不例外。但它确实给研究人类的学者们提供了一些建议。

  In particular, the experiment ensured that social rank was the only factor being changed, providing strong evidence that the chain of causality runs from low social status, through a disrupted immune system to worse health, and not the other way around.

  该实验的独特之处是,它确保了实验中社会等级是唯一发生改变的因素。它为因果关系链的正确模式提供了一个强有力的证据,正确模式是低等的社会等级通过被破坏了的免疫系统损害健康。

  The best medicine, then, is promotion. Prosper, and live long.

  而不是反过来的顺序。晋升是疗效最好的药物。因为成功,所以长寿。
