A biography is an explanation or a description of a person's life. It is an account of facts and experiences about him or her. It includes details on his/her birth, work, education, relationships, and death. Usually people who have lots of contribution on his/her field are the most common subject of biography. There is also a so-called autobiography. There is a big difference between a biography and an autography. Autobiographies are written by the person himself while biographies are outlined by other person.
