Last week was National Suicide Prevention Week. You missed it. We know so little about suicide that people worry awareness days might draw attention to the act and encourage some people to do it. For this, and for deeper reasons, suicide prevention week doesn't get much play. Although it would be ironic if suicides spiked on suicide awareness days, it would be an irony fully in keeping with this ironic act, to which, for instance, rich people in privileged nations are drawn much more often than poor people in failed states.
