Being sick ~20 days per year was the norm for me before remote work (and using N95 masks after it ended). Some people are lucky, others are not. (well, "luck" actually encompasses many factors such as population density, presence/lack of children, mandatory office presence, proper infection countermeasures in public places (air filtering, aeration), and I assume sufficient sleep or not (the only time I did not get sick as often without masking was when I managed to sleep 8 hours a day for a few months))
