"TEXT: the original words of an author or speaker, as opposed to a translation, etc.; any of the various forms in which a writing exists; the main body of matter in a manuscript, book, newspaper, etc., as distinguished from notes, appendixes, headings, illustrations, etc."
So, anything you write that describes you, your hobbies, your family, etc. is text. For example, NON-TEXT is a picture of you (how do people know it is "really" you just by looking at a picture??)
