Last Saturday, I found a gentleman waring an N95 medical facial mask in a train car of the Super Express from Tokyo Terminal. He had stood alone at a platform and gazed at others including me for a long time. He seemed to scrutinize every person who stood at the platform. All passengers had entered the train, and he followed me to choose the tail car of the train, that had no passengers. I looked at him and noticed of that he was the president and professor of a medical university, that is located near my town and is classified as an urgent care center for the covid patients . I realized that the medical doctor considered that the situation here in Tokyo was very much dangerous. Probably, he classified me as a person of preparedness for the danger, because I wore a medical eye-shield. Tokyo is in the midst of the covid terror. Nobody denies it. Who would like Tokyo Games this year?
