Dr. Oliver Sacks discusses his book "The Island of the Colorblind"
His book, "The Island of the Colorblind," was the result of Dr. Oliver Sacks' travels to Micronesia. Sacks was puzzled by how people that were color blind could tell if a banana was ripe. A man told Sacks that one must rely on the smell of the banana and its texture. The second part of the book is devoted to Sacks' travels to Guam.
