So you've spend a good part of your life in NY. That's gonna be
a little bit tough to uproot, but given your age, you should still
be very adaptable to a new lifestyle.
I suppose it really depends on how adventurous you are.
Since you have lived alone for so many years, you must be a very
independent person already. So even if you go live in a place like
Khazakstan, you'd probably still be able to survive and thrive.
There will be pros and cons. Being an Asian, you'd have less
problem with culture shock. Cons is, you'd still get a culture
shock. But it's just temporary.
The only way for you to be sure, is to spend some time in SG
before you commit. If you enjoy city life. You'd get plenty of city
life. A city that doesn't sleep.
Friends of mine who gets posted to Asia loves Singapore.
