Bangkok. Near victory monument. I think that the stress of worrying about AQI numbers is worse than getting on with life. Sure, the air quality in Bangkok will never be alpine fresh but WhyTF does anyone live here if they are paranoid about AQI. For most I know, they just get on with life. Don't like it, don't live here. Now, living in Chiang Mai from January to April would be a different matter for me - I would not do it. But then, so many expats head south, or overseas during those months. Just deal with it and stop complaining.
