Suicide has been a cause of concern in most societies for a long time. The classical Greeks, for example, required people who wanted to kill themselves to get permission from the senate. While this law is not without humor by today’ s standards, it clearly shows an awareness of the problem in times gone by. In today’ s society, suicide is much more prevalent than we want to admit. Why do people try to take their own lives
The motives for suicide can be categorized into areas such as failure, wrath, the need for attention, stress, and so on. However, the qualities of a person who wants to take his own life change from person to person, making it difficult to depict (描写) the typical victim. To make the problem even more involved, people will often camouflage (掩盖) their true feelings, thus causing their friends to disregard problems that should be viewed as serious.
