Pollution in Bangkok

I thought about this a lot in Shanghai- levels were over the top all the time. Never a blue sky. In Bangkok there is sun ans blue skies every day  But, I'm coughing, locals cough- and masks are seen on about 20%(?) of the population each day. I won't check again- it does not matter- I'm here.
The  "good" news is, I can't be re-infected with TB. Once you've got it, you're "immune" to reinfected. Oh lucky stars⭐️⭐️⭐️⭐️⭐️⭐️
