Koreans love plastic surgery...it's insane.\n\nAs for teeth, Japanese have horrid teeth for some reason(british level bad).\n\nKoreans have awesome teeth on average.\n\nAs for the ambulance, I think in japan it's covered by the national health insurance. In Korea I was in between jobs once and got ran over. the ambulance was like $300-$500 because foreigners need a job for national insurance to kick in.
