When we ask young men and women to go to war, what are we asking of them? When their deployments end and they return—many of them changed forever—how do they recover some facsimile of normalcy? MacArthur award-winning author David Finkel discusses the struggling veterans chronicled in his deeply affecting book, Thank You for Your Service with Skip Rizzo, Director for Medical Virtual Reality at the Institute for Creative Technologies at USC—who has pioneered the use of virtual reality-based exposure therapy to treat veterans suffering from PTSD.
