有些活动几乎不需要思考，例如玩某些视频游戏。通过练习，你会在这些活动中变得更出色。这个理念同样适用于一些有用的技能，比如打字或解决数学问题，这些技能具有实际的好处。还有哪些其他活动可以帮助工程师，或者一般来说有用且不需要太多思考呢？

Some activities need little mental effort such as playing certain video games. With practice, you improve at them. The same idea applies to useful skills like typing or solving maths problems, which have practical benefits. What other activities could someone do that are either helpful for an engineer or generally useful and need little thought?
