Wearing a mask is a necessary to prevent the sprade of COVID-19. Now, the number of infected people is small and going down not only in Japan, but also around the world. Nobody wears masks in the US when I watched baseball games on TV. They seem to get back to normal in their life. I think it is thanks to the vaccine and people’s natural immunity. I heard most people don’t wear a mask outside in the other countries. However, many people continue to wear masks even outside in Japan. I think we should wear them inside, for example, in a train car, dome stadiums, aircraft and crowded spaces, but we don’t need them outside. Wearing a mask in summer makes heat around our mouths and then we have a high risk of getting heat stroke, I think. Why don’t we take our masks off outside in the summer? That’s what I think!
