All those years of passive smoking in the UK have not been in vain. Today the smog is very bad and I know if I had virgin lungs they would struggle to cope. I can’t even see the end of the bay from the roof terrace! But what do you expect from a city of 22 million people (the same population as the WHOLE of Australia I’ll have you know!) and one of the fastest emerging economies in the world? Those face masks that Chinese people wear to protect themselves from Sars are looking very appealing.
