The so-called "activities, to live to move," you can according to individual fitness, time, place, make different exercise, don't say you are too busy, it is not reason!
所谓“活动活动，要活就要动”，你可根据个人的体能、时间、场所，做不同的运动，不要说你太忙，这不是理由啊！
I know it is effective because just a simple exercise a few minutes a day can make you feel different.
我知道这个有效因为一天仅简单的锻炼几分钟就可以让你感觉到不同。
You should still make them generic (for instance, accepting different parameters, and so on), but they are called from shell scripts (similar to the shell script you created in this exercise).
您仍然需要使它们为普通可用的(例如，接受不同的参数，等等)，但是它们是从命令脚本中被调用的(与您在这个练习中创建的命令脚本类似)。
