HK is Livable but sure is not healthiest
I was born in HK, lived there for half of my 40+ years life time.
I can ensure you there is Good connectivity, Good Shopping, Good Food, Good People, Good tax rate, Good mobile and fix line phone or internet. However as stated in the South China Morning Post, it is crowed, polluted, expensive, cramped, lack of cultural or natural asset.
With all the exciting night life, good food plus unbreathable and hot and humid atmosphere will let you go to see the maker much earlier than expected.
Sure Amsterdam or Sydney or Kyoto is a better place to live just without the good shopping.
