So that the animals on intermittent¹ energy restriction²,

就我们能测试结果来看

they'll live much longer with normal,

normal learning and memory, before they start having problems.

能以正常的学习记忆能力存活更长时间

So significantly longer?

Yeah, highly significantly.

是的 相当显著

We found in one study,

我们在一次研究中发现

six months to a year.

That's the equivalent in a human of the difference between

也就是相当于人类出现老年痴呆症状

developing signs of Alzheimer's at say, the age of 50, and the age of 80?

一种是在50岁 另一种是在80岁

The animals will have an earlier onset³

在学习和记忆力问题上

of the learning and memory problems.

它们更早开始出现问题

How much sooner?

快了多少

Um, three to four months sooner.
