the world need to learn how to cough or sneeze and basic personal hygiene. sneeze/cough in ur elbow or handkerchief etc.+ People need to learn how to wash hands.
i still freaking see guys not washing hands even after using bathroom. disgusting. dont remember, for years i have purell in my car, as soon as i get in, i use it, and specially after filling up gas.
human tendency is to touch face/etc without washing hands, so wearing goggles and mask basically (or a bottle cut out for that matter) help people from touching face.
