Flagler,
The decision to take the job is, as you say, up to the individual. I do however urge you to mark down this date in your diary and see exactly how long it takes for you to realise that most of what has been stated above re the ability to live in HK on COS18 is spot on. Not all of the posters above are altruistic in their motivation but that doesn't mean the message is not spot on. If you have a family but still insist on coming to HK be brave enough to admit a bad decision was made when you finally realise you should have listened. The price your family will pay is not worth hanging on out of pride. If you don't have a family then good luck to you.
Oh, and can you please let us know how long it takes?
