Ha ha ha, the " life expectancy " thing ( are you Donald Tsang ? ) is such a load of unequivocal bull5hit !!
The pollution has only been real bad for the last decade or so, if you take up smoking at the age of 70 you are hardly likely to die of cancer before you die of old age now are you ?
Even the government admit 1500 ( roughly ) die from pollution each year and 10s of thousands sick, yes, that 3 months of blue sky ( actually MAYBE 2 ) is obviously a good compensation for 9-10 months of toxic, heavy metal infested air.
Lets wait and see what life expectancy is like in 20 years, on second thoughts, I'll let you wait.
I'm outta here
