Reply #25: Males are far more successful in their suicide attempts

[Coyote_Bandit]

but females account for about 60% of all suicide attempts. The difference in "success" rates is attributed to the fact that men are far more likely to use firearms in their suicide attempts. I'm not sure that means that men are more vulnerable - it just means they are more likely to choose an effective and successful method.

Depression, mental disorders and substance-abuse are implicated in about 90% of all suicides. The risk for suicide is associated with decreased levels of serotonin - something often found in people with depression, impulse control disorders, and a history of failed suicide attempts.

For a variety of reasons those who commit suicide are unlikely to "dispassionately" see the problem or to craft a solution.
