Airports are obviously thunderdomes for the immune system.

I had to fly for work last year, and even being vaccinated, I got sicker than I had been in years. I had to conduct interviews with hundreds of people for my job. They weren't job interviews either. They were statistical interviews with random pedestrians. Shit sucked. I wore and sunglasses but it didn't matter. Still got sick. Been thinking about visiting my extended family. Might drive instead of fly.
