Hand washing isn’t exactly an arduous chore, especially since it’s done in the name of squashing germs, says Carl Borchgrevink, an associate professor at Michigan State University’s School of Hospitality and Business.
Regrettably, it’s a chore that often goes neglected.
According to a study led by Borchgrevink, only 5% of people washed their hands enough to kill infection and illness causing germs after using the bathroom. To make matters worse, 33% of hand washers didn’t use soap, and 10% skipped the hygienic step altogether.
“It’s horrifying,” Borchgrevink says. “A majority didn’t even make an effort.”
