A photo of a bloodied and unconscious teenager, a breathing tube protruding from his mouth, flashes on the wall.'That was me,' he says. There's a collective gasp before the room grows silent and Blomberg,31, an anesthesiologist who trained at Brigham and Women's Hospital in Boston, begins the story of what happened one night in February 1995.He created a presentation illustrating the dangers of behaving irresponsibly in a car, from not buckling up to speeding to driving under the influence of alcohol and drugs.

He realized that kids needed to hear what he had to say. He agreed to visit the school and began contacting others on the waiting list for his talks.Blomberg leaves the school hoping he has changed someone's behavior.
