By the way, my Lions Club is the 8th biggest club in Japan on the basis of the number of the members. About 110 people belong to the club and some of them are fond of running. They put together a running circle to evoke the health trend in the club and naturally I joined them. On the other hand, as the popularity of marathons has risen, students, who major in physical education or physical exercise in Ehime University, have voluntarily begun teaching citizens how to run and complete a marathon safely. I joined this circle as well. This circle is sponsored by the pharmaceutical giant, Otsuka Pharmaceutical Co., Ltd., which manufactures various sports drinks. It's very useful for people like me, who usually shy away from sports, to find out more about exercise, warm-ups, cool-downs etc.
The gadget in the picture - sorry for the lack of sharpness - is a device for carrying a bottle of water on the waist. In Japan, especially the southwestern part, is experiencing sweltering and scorching heat and thousands of people have been rushed to hospitals. Water is essential for running at present.
