I happened to watch a TV program broadcasted by Japan' public broadcasting service, NHK, in this morning. It was a surprise to me that the program focused on louses here in Tokyo! According to its report, many kids have louses on the head these days. I've never heard of such a horrible situation before the pandemic. Everybody knows that many people, either elder or young, had louses just after the second world war. However, it is the 21st century when we live daily life. Who could expect such nasty insects to have their nests in kids' hair. It is awful!
