When I was around twelve years old I read a book called "A Mango Shaped Space", which was about a girl with synesthesia, a phenomenom in which you connect colors with shapes or letters, or both, and the experience of losing her cat, Mango. It was heartbreaking but at the same time totally interesting, hearing for the first time about that amazing thing which is synesthesia. Later on in my course of studies in school, in my Theory of Knowledge class, I learned about perception and was even further fascinated about this phenomenom. Daniel Tammet illustrates how a synesthetic person sees the world and it's beyond ashtonishing. Hope you enjoy the talk!
