What is a hero?
Please answer it know, because I have to do an essay abpt heroes… thanks

Heroes come in all shapes and sizes. They can be anyone on from a parent who is always there. To a small child who does some amazing deed. A hero is someone who puts themselves out to help others when they are in tough times regardless of any thought to themselves, or danger to themselves. A young 14 year old boy was a hero in my state recently when he was the only one able to rescue a baby from its capsule in a car that had crashed. He rescued the baby and assured its dying mother that her baby was safe until she passed away. This boy although not famous or even an adult is a hero. He did things he didnt have to do without regard for himself. Some people also regard their favorite sporting star to be heroes. These people are seen as such just because they are in the media and not necessarily because of some great deed. So anyone can be a hero in someone elses eyes
