Secondhand smoke

I see. Yes hard to avoid, the winds especially. I noticed elderly men who smokes at public, they don’t care. They will smoke along the shelters/road if no one notice especially under the HDB etc. Or I see a group of people that is smoking. I will try to avoid from far or walk a different path if I notice they carrying a cigarette. Town area not so bad, bcos it’s strict. They need to smoke at certain area. Usually I will avoid the area too. As Long didn’t exposed for so Long is ok. I will just keep a distance / avoid from them.
