If we could simply use a few words to describe the life of each of us, I think it might be: birth, old age, illness, and death. Of course, not everyone can experience these four words in order. Maybe the baby who is just a few hours old will get sick directly before he grows up, let alone gets older. Maybe he finally retired, and when his eyebrows and hair turned white, he passed away before he could get sick... Human beings, there are always some stories of joys and sorrows in this life, and there are always some magnificent scenes. A life that is too smooth may not be like the life of ordinary people like us. It is like a life in one day, which should not be that interesting.
