Asking Koreans the Best Thing About Living in Korea

I asked Koreans, "What do you think is the biggest advantage of living in Korea?” (한국에서 살 때 가장 큰 장점이 뭐라고 생각하세요?)

For me, I love the transportation whenever I'm there and the overall ease of traveling to anywhere I want in a reasonable amount of time. I also appreciate the availability of hospitals in every area. And finally I like being able to get Korean food for a fair price.

What's your opinion? If you've ever lived in Korea, what did you like best about being there?
