What Makes a Hero

   This is going to sound like something out of a elementary school essay, but I think that a hero is anyone who is selfless and helps others, even in tough situations. Some people think that just because someone is famous, that makes them heroic, but there's more to it than that. In my personal definition, a heroic person helps someone when no one else would. They give up their time, their money, even their lives to help someone else.
    In thinking about being a hero, it makes me wonder, would I be brave enough to do something heroic? I imagine a situation in which another person's life is in danger and by saving them, I could endanger my own. Would I really be brave enough to save them, even if there was a chance I may be injured or possibly killed? It's sad for me to admit, but I don't know. I'd like to say I would, but until a situation like that actually arises, I can't say. And despite it being pretty selfish, I can understand a person being so scared that they'd rather run than risk hurting themselves. But what about you guys? Would you go straight for self-preservation, or try to help someone else in need?
