Like your wife, I have always carried antibacterial wipes too when flying and wipe my space down as far back as I can remember. I still have yet to fly anywhere since the covid-19 outbreak. But pre-covid19 I flew frequently. Sometimes monthly. I am planning to fly to Washington DC in February if I am recalling correctly. Like you, my thoughts on risk have also changed since the covid-19 outbreak. Overall, 2022 was probably the worst year ever for me since the covid-19 outbreak! Why was it the worst? One word, “work!” Non-medical management (educators) did not make it any easier dealing with covid-19. Because they were tired of “it” they decided it was over. No need for anyone to wear masks or receive any covid-19 education for that matter and crazily looked upon their school nurses as the “enemy!” NO joke!! Ugh... Way too many vested school nurses, one over 25 years of service to the district. She was also one of our practicing FNP’s. Several nurses quit! We even had a few brand new school nurses quit and went back to the hospital setting because they could not believe the complete madness of how the district not only treated their school nurses so poorly but how they played down covid-19. I for one am looking forward to 2023! I feel it will be a better year, even if we must still continue to fight for what’s right and continue to give covid-19 education!
I also used to get sick after most flights, and unnecessarily lost the first couple days of vacation to sniffles and sinuses, sometimes worse.
I had actually decided to start wearing a surgical mask on the next flight I took, stubbornly, and with determination not to feel like a freak, and then the pandemic hit, normalizing it! Now I wouldn’t dream of travel without an n95.

Happy holidays and safe travels :)

Kahneman and Tversky. Changed the paradigm for those who ponder risk.
