Society is changing rapidly. As a result, more and more people are suffering from stress. Those who are stressed out are often nervous, angry or ill. People must, therefore, learn to deal with this "new" kind of problem. Regular exercise is one way. The best way, however, is to keep a good sense of humor. After all, a good sense of humor is a life buoy in the waves of life.

翻译如下：

社会正在迅速变化。因此，越来越多的人承受着压力。那些压力过大的人常常紧张、生气或生病。因此，人们必须学会处理这种“新”的问题。经常锻炼(身体)是一种方法。不过，最好的办法是保持良好的幽默感。毕竟，良好的幽默感是生活波涛中的救生圈。
