Do people of different age groups differ in their response to e-mail messages? A survey by the Cent of the Digital Future of the University of Southern California reported that 70.7% of users over 70 years of age believe that e-mail messages should be answered quickly as compared to 53.6% of users 12 to 50 years old.
