Pity this post has got so far off track and is now a 'lets bag Hong Kong' theme. Karunch, I assume you choose to live in this city you think so unhealthy? I strongly suggest you do a little more research on airborne pollutants before trying to sound so pious. Sure the visibility here is adversely affected by output from the factories in Southern China, but it is interesting that there are more cases of asthma, percentage wise, in many cities in Oz than here. Canberra is a case in point. I believe the visible particulates are not the real concern but the ones too small to see. And by the by, talking with a GP about issues such as this, well I don't have much time for quacks and cannot imagine why one would have more knowledge on this or many other topics than for example you and me. Now I am not saying pollution is healthy, I am not saying that we should not be aiming for clear skies. But I am saying that it is easy to run down a place if you want to, I will stay in Honkers whether or not I can see across the water to the Gold Coast. The many advantages of this city clearly outweigh the disadvantages - for me at least. And those that don't like it, well their choice is clear (no pun intended).
