每次我使用方向盘时，都会摩擦掉一些微粒，但没关系，它还是原来那个物体。

Well--again, we gonna be careful about refining this, just like we all agreed, I suppose, that you can have the very same body even though somebody--the parts come and go, items get added, other items get knocked off.

我们得仔细研究如何对其定义,我们都认可了，先这么假设,即使肉体的某些部位丢失或新增,原来的肉体还是不变，肉体的某些部分可能新增可能丢失。
