I lived in Nigeria when I was a kid (10-13) because my parents thought it would be a good experience. It was. My Dad still didn't work particularly long hours though... I don't really get the relevance to a discussion on hours worked.
(incidentally, I was one of the very few Brit kids of that age out there - the rest were all packed off to boarding school if they were in secondary education - I went the American International School out there)
