(from a post with my Brown Class of ’68 page)

My current rant–because we are in the right age range–about face masks.
I chose to postpone my flight from Chiang Mai, Thailand, to JFK two weeks ago, partly because it was on Korean Air with a change of planes in Seoul, but largely because the US government looked woefully unprepared and was giving advice about wearing face masks that I believe is DEAD WRONG.
Despite huge tourist and business traffic between China and Thailand, there has only been a single reported death (by a smoker in his sixties with other health issues). The Thai government is corrupt and self-serving, but they turned Covid-19 over to medical experts, and as the medical faculty at Chiang Mai University advised my expat group a few weeks ago, people here DO wear N95, PM2.5 or similar masks. If they wear simple surgical masks, they dispose of them daily. What makes this admirable is that no people on the planet are my style-conscious than Thais.
It also helps the we “wai”–the Thai equivalent of “namaste”–instead of shaking hands.
