It is abhorrent to state that female suicide victims choose the method of suicide out of vanity.
In fact women chose "clean" methods that don't touch their faces because they are thinking of their loved ones. They do it for the same reason funeral homes have viewings, people need a face to say goodbye to.
Women are also more likely to consider the feelings of the person who finds them. Losing a loves one is devastating, finding them in a bloody mess just compounds the trauma.
