I remember the first time I went to South Korea and lived their for awhile when I was in the military. I was astounded by the use of face mask outdoors and indoors...even in parks. Not everybody did it but most did wear a face mask. They did it out of respect for those around them just in case they sick or didn't know they were infected with something. They also did it because the air quality had declined (pollution problems). Yet, these countries tend to out perform in their fight against airborne diseases than other countries that face mask wearing is not commonly seen. In fact, as soon as the Pandemic hit globally... I knew which countries will outperform other countries in the fight against Covid and I didn't need any prediction models to tell me which countries would do great and which countries would do poorly. wrbtrader
After tens of millions of cases and virtually zero documented cases of outdoor spread the pre commies still refuse to adjust their world views ...like good little drones. Keep wearing those masks outdoors...its a badge.
