After the terrorist attacks of September 11, 2001, it seems that our concept of heroism has changed. Where before we might talk about famous athletes, rock stars, and actors, now we are thinking about ordinary people such as firemen and policemen risking their own lives to save others. We are thinking about workers in the World Trade Center who helped disabled people down flights and flights of stairs rather than escaping themselves. We are thinking about the passengers on United Flight 93, who decided to attack the hijackers and prevent their airplane from being used to attack others. As the Chronicle of Higher Education put it, we are talking about ordinary people doing extraordinary things.In a well-organized essay, answer the following question:In your opinion, what makes a hero?
