An 88-year-old professor at the University of Georgia declared his retirement during a class when a student refused to wear her face mask properly.

Professor Irwin Bernstein told the University of Georgia's student newspaper, The Red & Black, that one of his students had shown up to his class on the second day of school without a mask. When a peer gave the student a mask to wear in class, she did not wear it across her face properly. She said she found it difficult to breathe with the mask over her nose, the most effective way to wear a face covering, health agencies such as the Centers for Disease Control and Prevention said.
