The bit below is a section from an email of a friend:
By the way, there's a bad cold going round, which it sounds like you caught. I went all the way through that thing, except I'm still coughing a bit. Humidifier, is my advice: a good humidifier and lots to drink. If only Koreans would cover their mouths when they cough, not everyone would catch this shit within 48 hours. (I'm sure I got it on the train, where this stupid asshole kept sneezing and coughing all over everyone, not once covering his mouth or even trying to do so. If that's the best they can do with their mystical 4300 years of culture, I'll take a shorter history where people have consideration and manners, thanks...)
Although I am quite interested in Korea's ancient culture, on this I have to agree with my friend. Basic hygiene can go a long way. Korea's habit of people spitting in the streets (in part encouraged by the buildup of phlegm due to the air pollution) is definitely not health promoting.
I think I mentioned once how great that ridiculous H1N1 flu scare was for Korea. Koreans suddenly started to actually wash their hands more often, particularly after a visit to the loo. The availability of hand sanitizer also increased. The first time I came to Korea it was terribly difficult to get hand sanitizer. Now most pharmacies keep it.
In any case, I feel sick and ever so slightly grumpy.
