1-cyberloafing 网络闲逛

2-rejuvenate 使年轻，使恢复活力

Cyberloafing: the line between rejuvenating and wasting time

3-plain old 普通的

4-slack off 偷懒

But when does a useful break become a plain old slacking off?

5-reset 调整，重新设定

6-procrastination 拖延

The key question is when a short break reset after a though task turns into procrastination.

7-recalibrate 重新刻度，再校准

Extending a break to recalibrate needs to be done with care.

8-empirical 经验的

9-suffice 足够

10-detachment 超然，冷漠

I don't have empirical evidence on how much cyberloafing is good. From experience though, I would say that about 15 to 20 minutes should suffice, but it vary among individuals. Anything beyond 30 minutes though may prolong the detachment from work and makes the transition back to work-related tasks difficult.

11-take one's unhappiness out 拿出，发泄

12-head to 前往，朝前面走

Too strict, the emplyees may take their unhappiness out by heading to Facebook anyway.

13-lenient 宽容的

14-dawdling 闲逛的，懒散的

Too lenient, and some may not be able to resist dawdling.
