I am currently reading "The Island of the Colorblind" by Dr Oliver Sacks. He is a wonderfully eclectic writer who manages to combine childhood exploration and excitement with scientific observations and conclusions. I love the titles of his books. They just make you want to read them. My favourite is "The Man Who Mistook His Wife for a Hat and Other Clinical Tales" Dr Sacks has been accused of exploiting his human subjects for his own benefit. One comment in relation to this accusation made me laugh: "the man who mistook his patients for a literary career".
