Get a raize and Dzun - are you two for real. Talk about putting your head in the sand!
I have been in HK for 20 years. The pollution has increased exponentially over the last 10 years to the point now where it's a disgrace. This 10 year period is not long enough to empirically calculate the effect it is having on longevity.
The old folks who are dying now are older than their predecessors because they have had better diets, fewer wars and for most of their lives clean air.
Their kids and grandkids don't have that.
So just watch the longevity curve turn and start to plummit.
Human beings' lungs just can't take the bombardment of such toxic chemical ingestion without serious health implications.
And Dzun - one good METAR does not dismiss this very real and lethal problem.
Why slowly kill your kids in this environment?
