I finished reading a book titled "Factfulness", which was written by Hans Rosling. It is a world best seller, so it is also translated into Japanese, but I read it in English for my study. It didn't take so much time to read it as the author showed a lot of data using graphs and they helped me a lot to understand what he wanted to say. Also, the experiences he had in various countries were so interesting and unique that I couldn't stop reading it. It's worth reading. I'm usually pessimistic about everything, but thanks to this book, I would be able to think a little positively. sembra naturale?
