After a certain pandemic that happened in humanity a few centuries ago, the use of masks at any time became commonplace. Even among the audience there were people with masks, even though humanity had dealt with that virus quite some time ago, but as a hygienic custom many people still continue to follow this and wear a mask to protect themselves and protect others from possible diseases. Of course, others just wore them because they thought they were cool.
