At a Monday press conference, Dallas Wiens, 26, discussed his life with a new face one year after receiving the first full face transplant in the United States. Wiens suffered life-threatening burns to his head when a boom lift he was driving drifted into a power line in 2008. In March 2011, doctors at Brigham and Women's hospital in Boston worked for more than 17 hours to give him a new face. (ABC News)
