Anecdote re: cognitive awareness: A friend's father was taken to the hospital, appearing to be unconscious...suffering congestive heart failure as well as treatment for colon cancer......about 85 years old....feeble, and a Hoosier's basketball fan (Indiana University/Bobby Knight)..... mentally alert prior to an "extremely rough evening". The son was asked by the attending physician if they should "DNR" Rob in case there was another "event" during the next 24 hours.............son hesitated before answering.........apparently a few seconds longer than Rob felt was necessary....because the "apparently unconscious" Rob had regained some strength and answered "well, I had really planned on watching Bobby (Knight) and those kids play on tv again tonight". ..........and he is still watching the Hoosier's play basketball......
