Suicide is the act of intentionally causing one's own death.Risk factors include mental illness such as depression, bipolar disorder, schizophrenia, personality disorders, alcoholism, or drug abuse.Others are impulsive acts due to stress such as from financial difficulties, troubles with relationships, or bullying. Those who have previously attempted suicide are at high risk of future attempts.
The most commonly used method of suicide varies between countries, and is partly related to the availability of effective means.Common methods include: hanging, pesticide poisoning, and firearms.This makes it the 10th leading cause of death worldwide. Rates of completed suicides are generally higher in men than in women, with males three to four times more likely to kill themselves than females.
Views on suicide have been influenced by broad existential themes such as religion, honor, and the meaning of life. The Abrahamic religions traditionally consider suicide an offense towards God due to the belief in the sanctity of life.During the samurai era in Japan, a form of suicide known as seppuku was respected as a means of making up for failure or as a form of protest.
