My son and I couldn’t go out today. We usually visit the playgrounds in the afternoon. The level of yellow sand in Seoul is “very unhealthy” according to the US Army’s Yellow Sand/Asian Dust Monitor System. It is advised that young children and the elderly should avoid all outdoor activities. Those with heart and lung problems should stay indoors too. Unless you have a medigap, it’s costly to get sick. I hope it will be better tomorrow as we wouldn’t want to spend the day indoors on a weekend!
