I've thought the things when I watched this scene in Gintama, "Nobody Prefer The Photo of Driver's License". It's true that few people can put up with the long training now. In Kamen Rider Series, we can rarely watch the training scene now, while it was naturally in Showa era. In Jump Comics too, it's said the popurality decrease if they write the story of training. In such era, I think how we should study English. In my case, derive from Dragon Sakura 2, in X(former Twitter), I write English phrases. If I feel like it, with smartphone, I record the video of speaking English, and also publish in X. According to Dragon Sakura 2, we can't learn language unless writing and speaking many times. In PC, it's useful because we can write English easier than Japanese and Chinese. It's OK that we take the TOEIC test, but at first, I think it's better to write English in X. Or, it's good to write English diary every day.
