I come across to know a book about how people think and some of the topics were analogy and metaphors . The book said it is an excellent tool to understand the object or phenomenon. As an example, Helen Keller was a master of those exercises. She was impaired in hearing and seeing, she only had a minimum way to interact with surroundings. However, she was able to understand and survive the world from other senses like touching and smelling. I thought that my senses are also being limited because of the quarantine. My living range has been decreased to my room which surrounded by four walls. I will use those tools to observe things outside of my four walls or inside of the banana where I cannot go. It is like spreading my mind.
