There are many similarity between doctors and teachers. First, both doctors and teachers are considering professionals by their communities. The classification of professionals is the high socioeconomic rank where an individual can achieve in this society. Second, both doctors and teachers help others: doctors heal to the bodies of sick people and return them to healthy. And teachers shape the minds of young people and turn them into responsible, educating adults. Last, both doctors and teachers are essential members of a community.
