In China, an increase of the aged population has been noted due to the following factors: (1) low mortality rate, (2) prolongation of life span, and (3) employment of the One-Child-Policy regulation. A study on the life cycle has been held in Shanghai and Zhejiang Province; the most concentrated areas of aged populations in China. Regarding the percentage of the aged within the Chinese population, Shanghai is presently compared with the Japanese population of 1980, while the Zhejiang Province is compared with the Japanese population of 1970. The Chinese life cycle has changed widely at the same time by prolongation of life-expectancy mainly among the aged population. Life expectancies are 73.5 in males and 77.4 in females in both areas. Therefor it has become very important in the aged population of China of adopting a policy of how to live a meaningful "Third Life". In regard to the above mentioned social needs, the Family Planning Committies of the Governments of Shanghai and Zhejiang have conducted an actual life survey on 1, 600 elderly people. The survey results on the life cycle of aged in China are follows; 1) The childbearing period which is the interval between the birth of the first child and that of the last child after marriage is 13.9 years. 2) The period of dependent children which is the duration from the birth of the first child to the graduation of the youngest child is 27.7 years. 3) The period of a three-generation household which is the term from birth of the first grandchild to death of the grandparent is 20.6 years in males and 29.2 years in females. 4) Male post-retirement period which is the term from retirement to death is 13.5 years. 5) The period of dependent elderly parent which is period from father's retirement to the death of the both spouses is 21.0 years. 6) The period of widowhood which is the term between the deaths of the two spouses is 8.6 years.
The Japan Poison Information Center (JPIC) received 205, 199 inquiries from citizens and medical personnel for 5 years from April, 1989 to March, 1995. And, the number of inquiries concerning with suicide in those was 5, 778. In July 1993, the book named the Suicidal Manual were published in Japan and since then, the inquiries concerning with suicide attempts have increased. So, I analyzed these data about implicated products and contrasted the data received before the publication of the manual to the data received after that on purpose to make clear the affection of the Suicidal Manual. In regard to the substance that was selected in suicide attempts cases, teen-ager and the twenties tend to use medicines, especially over-the-counter drugs and older people tend to use agricultural chemicals. After the book was published, the number of inquiries about some over-the-counter drugs that were shown as appropriate way for easy and painless death in the book had increased. So, it is very important to give the young people the information of drug toxicity and appropriate management of drugs to decrease the influence of the book.
