In physics, drag refers to the resistance experienced by an object moving through a fluid medium (such as air). Zero drag is an ideal state where the object experiences no resistance at all, much like a highly motivated employee who has few personal responsibilities and so can work long hours, travel frequently, or be called in to work with little notice.

从物理学的角度看，drag指物体在穿过某种流体媒介（如空气）时受到的阻力，而zero drag则是描述物体不受任何阻力的理想状态。这种零阻力的状态就像工作热情极高又没有什么个人责任负担的员工，可以长时间工作、频繁出差、有任务随叫随到。

 

The ideal zero-drag employee is young, unmarried and childless with no responsibilities and an eagerness to do well.

理想的零阻力员工一般都年轻、未婚、无子女负担，而且渴望将工作做好。
