In 1960, President Kennedy challenged young people to join the Peace Corps. Why might someone want to join the Peace Corps? Peace Corps volunteers help people in developing nations. Peace Corps volunteers might counsel teens in Belize, launch a computer center in Armenia, or teach chemistry in a high school in Ghana. Since the 1960s, more than 178,000 Peace Corps volunteers have had the satisfaction of living and helping others in 138 countries around the world. Individuals who join the Peace Corps know that they have served their country, served humanity, and made a difference in the world.
