And a lot of other universities. Stanford is supposed to be a top university and have the best and brightest students, yet they have proven not to be. In an informal study, students were more likely to wear a mask while biking instead of a helmet. This despite the fact that the risk of fatality from a bike head injury is conservatively 100 times greater than the risk of dying from Covid, and that doesnlt even consider the outdoor factor.
You see this phenomenon all over college campuses and left-leaning cities where young people mask up while outside. It is silly and embarrassing.
