I was born and raised in Singapore up until I was 12 when I moved to England for boarding school. Now I've moved to Norway.
If you go with an open mind, then the sky is the limit in terms of what you can or cannot do. Singapore is a good place to be, often wonder why I left and often harbour the thought that someday I will pack up my life here and return.
There are many people who don't like the weather that lives in Singapore, reality of it is there are actually very little reasons to be affected by the climate if it isn't something you appreciate a lot. Just about anything and everything that can be air conditioned has already been airconditioned, in a few years I'm sure they would have found a way to air condition the streets too
You will be glad for the heat at times, buildings tend to be cooled rather liberally that it often feels just like winter. The biggest problem about the climate isn't so much the humidity, what's really tough is when the haze arrives from neighbouring countries.
Many parts of Singapore, you won't really feel that you are in Asia as it has a big expatriate community there. In the condo block I used to live in, there was only 1 other family from Singapore that lived there, nearly everyone else were either from USA, Australia or Japan.
The good part about Singapore, it is perhaps one of the most meritocratic and competitive societies in the world, many of the top doctors have foreign origins and that's the beauty of the system there, if you are good they don't care where you came from (granted if you were black it MAY cause some problems),
I did consider moving to Switzerland last year, however I felt that I'd miss the views of the oceans that I can see just about every morning here. Also felt at my age I was too old to try moving to a place that I knew nothing of the language as well as I felt it was unfair on my kids to uproot again after haven got used to things here.
