Head wave continues across Japan. These days, the temperature here is nearly 35 degrees. However, my room doesn’t have an air conditioner! Furthermore, I cannot concentrate in air outside. So when I’m studying, I close all windows in my room and start the fun. Not for me, for my surroundings. Because I don't like the wind blow against me. But I found an article which says that “The Fire and Disaster Management Agency and health ministry are advising people to stay hydrated and keep cool.” Gush! My room currently is against it. Oh really, I have headache and feeling heavy these days… I have to be careful for the heatstroke.
