When I read the article, I remembered the conversation which if you have to lose your ability of ear or eye, what do you want to keep it? ear? or eye? It is very tricky question. someone chose ear, but many people chose eye. I chose eye too. This is because, my research area focus on visual things. Moreover, there is more alternative way if you lost ear than eye. For example, sign language, written language and so on. However, you imagine your life without music, people’s voice. voice or sound is more emotional than visual. What do you think? It is really hard question.
