There was no hair not perfectly coiffed into shape, no upper arm that was not toned into submission by some rigorous daily workout.

有头发有完美地梳成形状，有上臂有通过一些严格的日常锻炼而得顺从。

But humans have been cutting and coiffing their hair for at least 25,000 years, mostly with the aim of pleasing themselves and distancing or differentiating themselves from others.

但至少两万五千年以来，人们一直在修剪、己的头发，主要是为了满足己、胜过别人或是让己显得与众不同。
