Taiwanese attitude towards smoking is surprisingly modern.
A Yahoo Taiwan survey of 47,000 responses on November 12-15, 2019, shows that 11.9% say they smoke daily, 77.3% do not smoke, and 6.2% do not know or have no opinion about whether they smoke or do not smoke!
What?! There are 6.2% who do not even know whether they smoke or not?!
There are 58.1% who have a very strong aversion towards second hand smoke, 22.9% have some aversion towards second hand smoke, 9.7% are unaffected by second smoke, and 9.3% do not know or have no opinion as to whether they are affected by second hand smoke or not!
What?! There are 9.3% who do not even know whether they are affected by second hand smoke or not!
The only possible explanation is that these people do not have any sense of smell! They cannot smell second hand smoke!
