They find, all of a sudden, that they can no more / longer carry on the job they have done for dozens of years. Some old people cannot adapt themselves to such a change and thus become depressed, believing that they are no longer useful. Indeed, depression has become one of the leading threats to old peoples health. Nonetheless, many old people in China are able to maintain their sense of usefulness by rendering their grown-up children services, such as taking care of their grandchildren and providing allowances to them. The question remains as to whether senior citizens should try other means to fill up their leisure, rendering their later years still more meaningful. I suggest the old concern themselves less with their children and make room for young people to take responsibility for their own lives. After all, the old deserve respect from the young and the young should tolerate their aged parents more, on the grounds that the old have contributed so much for so many years both to their family and to society.THEME-RELATED WRITING1. AIDS Across the EarthAIDS has killed and is threatening to kill millions all across the earth. Several million infections are reported by WHO each year. The virus does not care whether you are black or white, male or female, young or old. It will attack you as long as you are a human. Today, AIDS has become the leading killer of young adults and is turning the children whose parents suffer the disease into orphans. It is no exaggeration to say that we live under the shadow of AIDS.There are several possible causes for such a situation: unsafe sexual intercourse; sharing or reusing contaminated needles; transfusion of contaminated blood or blood products; an infected persons pregnancy, giving birth and breastfeeding, etc. Unfortunately, our ignorance, prejudice and silence have carried the situation to a desperate extreme. Patients are isolated or treated as outcasts by their families and their communities. AIDS victims feel ashamed to be identified as such and try hard to hide their disease. For this reason, they cannot get immediate medical treatment. Our harmful attitudes towards the disease and its victims have actually placed more people at risk. In our fight against this deadly disease, we should educate people on how to avoid being infected with the disease and how to lead a healthy and secure life and, more importantly, how to treat AIDS patients properly. Only in this way can we really bring AIDS under control.2. Why Do the Young Adults Kill Themselves?Young adults are in the prime of their lives and are supposed to pursue their dreams and enjoy themselves. Yet it was reported in the Guardian that suicide is the main cause of death among young adults in China. Why have so many yo
