Why do people always know the importance of health when they are sick?

Because pain is convincing, when we pursue happiness, everything is left behind, and so is health. The pain when you are sick will make people regret it, and then you will calm down and recall all kinds of mistakes in the past. These are common problems of people. Once the body returns to normal, it will soon forget the disease. This can't be said to be bad. How sad it would be if people kept living in vigilance and pain.
