I've worn my mask indoors and been out and about and have been dining inside at least once or twice per week. I'm also in K-12 education around several thousand of student and staff. We have been in school since August when the school year began. I also vacationed out of state in the fall.
I think my secret to not getting sick at all throughout has been good hygiene, some social distancing mask wearing, and a regiment of vitamins taken twice daily.

I did direct work with three people who have large families and play sports who did catch the virus and exhibit symptoms so I'm doing something right.
I'm hoping for a vaccine for school staff come soon. I'm just a few months away from the age 60 cut off in Indiana.
