Post-Traumatic Stress Disorder gets a lot of airplay these days. I don't want to downplay it because (as you'll see below) I'm a card-carrying member of the PTSD union. But I think it has simultaneously gotten too much casual attention in our culture and not enough deep attention. 

"Oh yeah," we say, "Joe's got PTSD." And then we wave it off, as if it's somebody else's problem. But the problem belongs to society, to humanity. The number one thing we can do about it is to stop putting people through trauma.
