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

有头发有被完美地梳理成形，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，人们一直在修剪、打理自己的头发，主要是为了满足自己、胜过别人或是让自己显得与众不同。
