The term 'Brief Life' can be summarized by two crossword solutions: BIO (3 letters) and AUTOBIO (7 letters). BIO is an abbreviation for biography, which is a written account of someone's life. An autobiography, or AUTOBIO, is a self-written account of one's own life. Both biographies and autobiographies are written accounts of a person's life, but the difference is that biographies are written by someone else, while autobiographies are written by the subject themselves.
