I used to get sick a lot more often, pretty consistently 3-4 times per year. Since I’ve started masking on trains (specifically because others who are sick and coughing aren’t wearing a mask) and other things (elderberry, zinc, NAC at signs of cold) I’ve gone down to 1-2 times per year. And that is mostly from hooking up with people who had COVID and didn’t realize it.

It’s hard to say exactly what led to the reduction in illnesses, but the N95 masks have the strongest evidence base of the interventions I’ve tried.
