I lived in Sweden for 5 years. The further you go from the cities, the less people speak English. Ja, ja! :)
Seriously, I worked for a Swedish company for 12 years in 3 countries so the Swedish came in handy. Like an English speaking Filipino who likes to speak Tagalog, the Swedes prefer speaking their language and it's an advantage to speak it with them.
I kept thinking about this article, closet geek that I am. I remember that the foreign words, that I would remember easily, would be the ones that I would hear again sometime after I learned the word. This is in line with Wozniak's hypothesis. Jätte fint!
