I've lived overseas in Cambodia and Taiwan. The lower cost of living, warm weather, and challenges of living in a different culture can make life pretty enjoyable.

I chose both places carefully and visited before deciding to move. I still visit the US once a year and my vacations now take me to places I would never go if I lived in the US. A weekend trip to the Philippines, Vietnam, South Korea, China, or Japan is feasible from Taiwan. From Cambodia, you're right next to Vietnam, Thailand, and Laos, all safe places if you read up on what to watch out for.
