Only when people lose their health can they know what is the most precious.

Yes, that's human psychology. They only know how to cherish it when they lose it, but they don't think about these problems when they live normally. Who always thinks about getting sick one day? Thinking in that direction is also easy to cause mental health. Positive, losing health is also painful. After a period of time, they will return to normal life. They should also learn to forget the pain, face life optimistically and face reality.
