question: My author's uncertain yet my title's the same,  I contain random text yet order's my aim.   Read me one day and see my pages are totally bare.   Try again another day and the words will be there.   I'm not a book of magic although it may sound,  I can predict the future, and inside, your life can be found.   Move my eye, I become involved in lactic extraction.   But that's just a clue , a minor distraction.    What am I?
