Where is my “I,” the self , philosophy homework help

In an amusing way, Dennett raises a question also addressed by Descartes, am I my brain (mind) or my body, or some combination of the two? Where is my “I,” the self that is supposed to subsist throughout changes? He shows that this seems to be an impossible question to answer, thus undermining the concept of the self. Explain why Dennett believes it is impossible to answer this question, why all attempts to define the self as mind, body, or a combination of the two fail. (Due: 11:59 PM Sunday.
