Body modification (or body alteration) is the deliberate altering of the human body for non-medical reasons, such as sexual enhancement, a rite of passage, aesthetic reasons, denoting affiliation, trust and loyalty, religious reasons, shock value, and self-expression. It can range from the socially acceptable decoration (e.g., pierced ears in many societies) to the religiously mandated (e.g., circumcision in a number of cultures), and everywhere in between. Body art is the modification of any part of the human body for spiritual, religious, artistic or aesthetic reasons.
