Whn writing a biography , authors must research the subject of a biography before writing. However, while a biography is about the life of a person it does not tell you every single detail about the person.
A biography, or simply bio, is a detailed description of a person's life which includes more than just the basic facts like education, work, relationships, and death; it illustrates a person's experience of these life events.
Even though biographical works are usually non-fiction, fiction can be used to portray a person's life as well.
