I have done this several times during my childhood - while it was very difficult learning new languages and cultures, I was able to see and learn a lot of new things that I wouldn't have been able to if I had just lived in say the US because the world is very different out there (especially in 3rd world countries) - in one, primarily agricultural country, I have seen women give birth each year in appalling conditions because there is no birth control and anyways the extra hands were needed for the farms - in another I saw men marry a second or third time if the first wife did not give them the desired child - there is little or no choice in those countries
