In my abnormal psychology class, we learned that men had a much higher success rate in suicide, except in places where women had ready access to highly lethal poison.
I understand that your comment is facetious, but I think there may be something to this line of thinking. Men are more likely to follow through with their actions, due to immense social pressure for success. Even if that success is killing yourself, I think a lot of men would rather a successful attempt than an unsuccessful, just to avoid the shame of failing at something so serious.
It's because men are more likely to use a gun to commit suicide while, for whatever reason, women are more likely to down a bottle of whatever there is in the medicine cabinet that they think will do the job. This ladder approach backfires if you dont know whether a specific medicine is designed to induce vomitting in large doses or how to negate that concern (and with suicide being tied heavily to moments of impulsiveness, by the time you finish the research your resolve may have left you)
