The pain of recovering in the hospital made me realize the deepest thing is to have a good body. Many retired uncles and aunts, uncles and sisters in their early forties are receiving rehabilitation treatment because of cerebral infarction or cerebral hemorrhage. Most people have no smile on their faces, full of vicissitudes and unhappiness. The relatives who take care of them also look tired and pretend to be happy just to encourage them. They suffer from physical numbness and pain, and their spirit is almost exhausted, which is enough for me to deeply understand the importance of the body. Without a healthy body, there is no real happiness. Many times money can't buy health, nor can it buy heartfelt happiness and happiness.
