Maybe you need to check out the air quality in your area and monitor the fine particulate content which is what sensible people appear to have been doing prior to Covid particularly in high population density areas such as Bangkok and other large conurbations?
I'm still alive having arrived just over a year ago with the trip taking around 24 hours door to door. I didn't suffocate. Neither did I suffocate jogging in Bangkok with a mask when we lived there. Guess I must just have been lucky?
