One of the reasons they left.
I know quite a few people that have left HK. One of the major reasons they left was the pollution. I would just hate to be bringing up the developing lungs of young childeren in such an environment. In 2005 a respected professor in HK announced that in his opinion it is not worth exercising in HK as the elevated breathing and consequent ingestion of particulates, off set the benefit of excersise. It will also not be getting any better in the furture because it incures a economic penalty to business. And we know how Honkies feel about money don't we.
I know my profile says that I live in HK. I left too.
