Some people find it fun because they enjoy detective work and like to solve puzzles.
Others are fascinated with certain periods and places, with some of history's great dramas, or with the ebb and flow of events. However much we may want to, we cannot escape the relevance of history to our lives. It's not even past. The past lives, and we study history to connect our past with our future and to give meaning to our present. One of the most widespread assumptions among students and parents is that studying history prepares one to teach, but not to do anything else.
