Jill Price has the first diagnosed case of a memory condition called hyperthymestic syndrome -- the continuous, automatic, autobiographical recall of every day of her life since she was fourteen. Give her any date from that year on, and she can almost instantly tell you what day of the week it was, what she did on that day, and any major world event or cultural happening that took place, as long as she heard about it that day. Her memories are like scenes from home movies, constantly playing in her head, backward and forward, through the years; not only does she make no effort to call her memories to mind, she cannot stop them.
