Suicide is more common than we measure and can be impetuous:

  Three days after a publicized suicide, automobile fatalities increase by 31%. The more the suicide is publicized, the more the automobile fatalies increase. The age of the drivers is significantly correlated with the age of the person described in the suicide story. Single-car accidents increase more than other types just after the publicized suicide.
