It improves your chances significantly that you won't get the season's most prevalent flu viruses though.

Very happy to hear of your awesome experience doing missionary work! I myself went to Beijing a few summers ago to teach English and spread the gospel as well. I found that language wasn't much of a barrier because most Chinese students know English relatively well. Did you have problems communicating? I'm guessing you had a translator? I'd be interested to hear how your experience differed from mine :)

Did each tribe speak a different language, or just a different dialect of the same language?
