So we all suffer from this some kind of memory decay.

所以我们都会遭受这种记忆衰退。

Since Ebbinghaus's days, our understanding of how memory decays has come a long way.

自艾宾浩斯的发现以来，我们对记忆如何衰退的理解取得了长足的进步。

While largely hypothetical and simplistic in its details, this model demonstrated how memories decay quickly unless accessed again and again.

虽然这个模型在细节上很大程度上是假设性的和被简单化的，但它证明了如果不反复使用，记忆是如何会快速衰退的。

In the 1880's, a German psychologist named Herman Ebbinghaus wanted to understand how memories decayed over time, and he especially wanted to know how long the process took.

19世纪80年代，德国心理学家赫尔曼·艾宾浩斯想要了解记忆是如何随着时间流逝而衰退的，他尤其想知道这个过程需要多长时间。
