What the F—Happened? That’s what 30-year-old Reggie Colby asks. He says he had a happy childhood, tried heroin at age 18, married and dropped out of college, joined the army, and became addicted after an injury in Afghanistan. Since then he has been dishonorably discharged, divorced, and estranged from his daughter. Now he is sheltered by an overpass in Camden, New Jersey, two days after serving time in jail for stealing food. “What happened?” is the right question. Did the stress of emerging adulthood have anything to do with it?
