In the morning, I decided to go swimming in a pool at Ariake Sport Center. I, however, have forgotten where my swim suit is. So, I gave up the plan. As substitute for it, I jogged along the sea between “Fune no Kagakukan” and “Odaiba Kaihin Koen”. Although it was week day, there were many people because of spring break. I had not jogged about for several months since I felt it had been too cold to jog outside. I had been in totally lack of exercise. When I was jogging, I felt that I was killing something not so good in my body. Anyway, I have to find my swim suit. Where is it in the world?
