"If a school year includes 180 days of class and each day has 6-8 bell rings, then that adds up to over 16,000 rings by the time a student graduates from high school. It is the first time that I realized what this means about the curriculum of most schools in the United States. It means that responding to bells is one of the more reinforced and near universal lessons in a school experience."
