Why do the best athletes in the world not wear facemasks during competition?
During the recently completed Tokyo Summer Olympics, I noticed athletes wearing facemasks while not competing.
I did not notice any athlete wearing a facemask while competing. No basketball nor soccer player, no gymnast, no sprinter, no shotputter, no weightlifter, no archer, no diver, no swimmer wore their facemask while competing!
During fierce competition, athletes are very close to each other, while their bodies are directing all energy toward their best physical performance.
If facemasks have any positive effect on C19, why do the best athletes in the world not wear them during competition?
