In early American history, a hero was a man who was wise, brave and able to save his country from trouble. George Washington was a great American hero. He fought courageously in the Revolutionary War and won independence from Great Britain for the United States. His wisdom and leadership were largely responsible for the organization of the government and for the development of the country.
    The modern American hero must be daring and independent as he solves problems. His problems may or may not be national ones. Most of the time they are problems that involve principles like religious freedom or civil fights. For example, Dr. Martin Luther King Jr., a modem hero, tried to achieve equal rights for the American black people. He gave his life for the principle of human equality.
    However, most American heroes are those who axe less concerned with national crises than they are with simple, everyday problems in life. American heroism can be seen in those who rush into burning buildings to save books and manuscripts; who run into paths of automobiles to save the life of a stranger; who work very hard to do credit to their family or faith through sports, music or volunteer services.
    In brief, anyone in America can become a hero, and everyone should try to behave like a hero.
