Obsessions are a type of neurological disorder characterized by the recurrence of obsessive-compulsive thoughts. Compulsive ideas are thoughts, representations, or intentions that repeatedly enter the patient’s field of consciousness in stereotyped form. These thoughts, representations, or intentions are not realistic, unnecessary, or redundant to the patient; the patient realizes that they are his own thoughts and is distressed by the fact that he would like to get rid of them but is powerless to do so. Compulsive actions are recurring stereotypical behaviors or ritual actions that are the result of the patient’s submission to compulsive ideas in an attempt to reduce internal anxiety. In recent years, I have received many cases of such compulsions. Whether it is compulsive ideas or compulsive behavior, after the doctor’s explanation, most of the patients admit that the main cause of the disease is the internal insecurity, always worried that if they do not act according to this feeling inside, what if something happens? Therefore, the cause of the disease is always the word “fear”, and the logic of “fear” is always the fear of “what if”. When I see patients suffering so much, sometimes I tell them the story of the “wolfish man worried about heaven”. There was a man in Qǐ who was so worried that heaven and earth would collapse and he would lose his place of dependence that he could not sleep or eat. Another man was worried that he would have problems because of that worry, so he went to him and said, “Heaven is the gas that is gathered together, and where is it going to collapse? Why should you worry about its collapse, when your body stretches and breathes in the heavens all the time?” The man said, “The sky is indeed the gathered gas; what about the sun, the moon, and the stars, will they not fall?” The man who advised him said, “The sun, the moon, and the stars, too, are luminous gases among gases; even if they fall, they cannot hurt anyone.” The man said, “What if the earth collapses?” The man who advised him said, “The so-called earth is a collection of many clods of earth, which fills all the corners of the four directions, where else would it collapse clods of earth? You walk and jump, all day long on the ground, why worry about the ground will collapse?” So the man was relieved and happy, and so was the person who advised him. In fact, according to modern scientific knowledge, we know that there is still a lot of truth in worrying about the sky, and the fact that the man was persuaded was only a partial truth. The sky does collapse, and this is the phenomenon of the ozone layer hole. Anyone with some scientific knowledge knows that the ozone layer is the largest concentration of ozone in the atmospheric stratosphere and is a protective layer for the earth, where most of the sun’s ultraviolet radiation is absorbed. The hole in the ozone layer is an empty space in the atmospheric stratosphere where the concentration of ozone is greatly reduced. Ozone is distributed in the atmosphere from the ground to 70 km above sea level, with its maximum concentration at 24 km above sea level at mid-latitudes, decreasing slowly toward the poles, and its minimum concentration at 17 km above sea level at the poles. The ozone concentration in the ozone layer is decreasing. The decrease in ozone concentration in the ozone layer has increased the amount of ultraviolet radiation from the sun to the earth’s surface, which has a damaging effect on the ecological environment and affects the normal survival of humans and other living organisms. For more than 10 years, scientists have studied; for every 1% reduction of ozone in the atmosphere. UV radiation to the ground will increase by 2%, human skin cancer will increase by 3%, but also by cataracts, immune system deficiencies and developmental arrest and other disease attacks. Now living closer to Antarctica, the residents of the southern tip of Chile’s Helena headland, has tasted the bitterness, as long as you go out of the house, you have to cover the skin in clothes, coated with sunscreen, wearing sunglasses, otherwise half an hour later, the skin will be sunburned into a bright pink, and accompanied by itching; sheep are more cataracts, almost completely blind. It is said that the rabbits there are completely blind and hunters can easily pick up their ears and take them home, and the fresh fish caught in the river are blind. By extension, if the entire ozone layer is destroyed, the sun’s ultraviolet rays will kill all terrestrial life, and humans will be “exterminated”, and the earth will become a barren land without any life. It can be seen that the hole in the ozone layer has threatened the survival of mankind. Back to the story. The State of Qi, a vassal state of the Zhou Dynasty, existed from 750 to 445 B.C., more than 2,000 years ago. The man who was worried about the sky falling has been turned into dirt, but his worry has been a common phrase in our daily life, “Qǐ Ren is worried about the sky”, which is used as a metaphor for unnecessary or unfounded worries and concerns. Suppose, if he were really alive and saw the existence of the ozone hole, and his fears were confirmed to be justified, how would he feel? If he did live long enough, how would he want those years to be spent? To sleep and eat in fear, or to accept this uncertainty of life and human limitations and live each day authentically? I know that every one of my compulsive patients is compulsive because they drill down into some aspect of their lives and ask questions. They ask questions that are not baseless and illogical, like a worrywart who wants to be sure of one thing before he or she can move on to other things. But what they do not see is that the biggest contradiction in their logic is that life itself is uncertain, insecure and imperfect. Maybe, one day, they finally figure it out, but a fifth, a quarter, a third, or even a half of their life has already passed, or one of the best parts. When they are old, their epitaph will probably have the phrase: This is a great warrior who fought with OCD for most of his life. Who, I wonder, would accept spending their life like this?
