Body piercing, a form of body modification, is the practice of puncturing or cutting a part of the human body, creating an opening in which jewelry may be worn. The word piercing can refer to the act or practice of body piercing, or to an opening in the body created by this act or practice. Although the history of body piercing is obscured by popular misinformation and by a lack of scholarly reference, ample evidence exists to document that it has been practiced in various forms by both sexes since ancient times throughout the world. Body piercing was started a lot of years ago before Cristus. The practice of body piercing has waxed and waned in Western culture, but it has experienced an increase of popularity since World war II, with sites other than the ears gaining subcultural popularity in the 1970s and spreading to mainstream in the 1990s. Ear piercing has been practiced all over the world since ancient times. There is considerable written and archaeological evidence of the practice. Mummified bodies with pierced ears have been discovered, including the oldest mummy body discovered to date, the 5,300-year-old Ötzi the iceman, which was found in Italy.
