This is followed by a latency period.

之后会有一段潜伏。

It's only after what the psychiatrists call the latency period that I began rebelling, asking questions, and the questions remained open.

只是在精神病家所说的潜伏过去之后，我才开始反抗，开始问问题，这些问题仍然是开放的。

But how scientists figured out this latency period is exactly how they figured out what the funniest joke in the world is statistically.

但是科家们计算这个潜伏的方法也和他们计算世界上最有趣的笑话的方法一样。

So they’re actually infected without having any symptoms of disease. This latency period can last for several decades.

所以他们实际上是在没有疾病症状的情况下被感染的。 这个潜伏可以持续几十年。

During these initial stages of replication, called the latency period, a person may not show any major symptoms for up to 8 years.

在复制的初始阶段间，称之潜伏，感染者不会表现出主要症状，这段间可长达八年。

And also in fact, scientists have found that there's a 17 day latency period between a national tragedy happening and you being able to make a good joke about it.

事实上，科家发现，从国家悲剧发生到你能够用这个话题来讲个好笑话之间有 17 天的潜伏。
