Keep your eyes peeled: A Chinese teenager slipped and stabbed himself in the face with a 7cm knife while peeling an apple. Ren Hanzhi's father recalled: “He was walking to the sofa while peeling the apple. Suddenly he slipped down and his face hit onto the sharp knife. I dared not pull out the knife as my son was screaming”. The nearest hospital referred the 13-year-old to a larger unit. Chief surgeon Peng Liwei, who operated to remove the knife, commented: “It's shocking. The knife, which is more than 20cm long, penetrated 7cm into his face. The surgery was successful and the patient could recover fully in around a month”. (Photo by Rex Features)
