In reading this, you get a sense that Daniel Tammet is a genius. You also get the feeling that he's been told that a few too many times. And, yeah, while I'd be another one of those people who'd be in line to reiterate how amazing I find his mind, you don't necessarily want to read a book about the author being the example of brilliance. When he's running facts and talking about the history and studies of math, language and their usage within the human brain, he's great. When he's talking about himself, it's annoying to the point where I started skipping tracks here and there of the audio. Also, it's about 3 discs too long for the content. I give Tammet kudos for the attempt and still find him a delightful mind to while away the hours with, but if you're going to indulge in his work, savor "Born on a Blue Day" instead.
