December 13, 2010:

You emerge from under the bridge into a dirt road in bright sunlight. A man in a peach-colored sport coat nods casually. But as he passes you see a package of drugs and a hypodermic needle in his pocket. Is this a place where junkies go? Before you can react he calls out for help. "I've injected myself and I'm bleeding!" Blood streams from his right arm: he's opened an artery. You tell your friend, "Put pressure on the wound and tie a tourniquet tight above it." You have your cell phone and are running for help when your head spins. You're queasy at the sight of blood.
