Suicide

If you're a man under 50 the person most likely to kill you is yourself

roughly a million people top themselves every year
that's a lot of people
imagine them all jumping off the same roof
at the same time
imagine a whole city
turned to ghosts overnight
imagine ten self-inflicted Dresdens
every year
imagine the aftermath
imagine the cleanup operation

except we shouldn't have to imagine
because it happens all the time
but it's hidden
it's quiet
because no one wants to talk
about our own worst enemy
