According to the Associated Press, a construction worker is expected to make a full recovery after a workplace fall left six nails in his head. The worker, Isidro Mejia, was injured when he fell from a roof, striking a co-worker who was holding a nail gun. As a result of the impact, the gun discharged. Three of the nails entered Mejia’s brain while one entered his spine. Miraculously, none caused permanent damage to the brain or spinal cord.
