Dillian tells his story in a fast-paced style that sweeps the reader up into the author's two worlds: the bare-knuckle world of price discovery on the trading floor, along with his descent into depression and the constant coping with his nearly debilitating obsessive-compulsive behavior. All of this makes the book hard to put down.

Street Freak is a great American success story — with a twist. A young man gets out of the Coast Guard and dreams of having a Wall Street career, working in the center of capitalism — the World Trade Center. But he doesn't have the top-tier college pedigree that paves the way to the brass ring. The competition is fierce in the Lehman Brothers training class. He has a slim chance of earning a position.

His training is rudely interrupted by 9/11 and the author must live with the memory of watching the second plane ram into the second tower right above him.

Levitt and Dubner name their chapters provocatively to reel the reader in: for instance, Chapter 1 is entitled, "What Do Schoolteachers and Sumo Wrestlers Have in Common?"

Levitt and Dubner spend a quarter of the book on parenting and kids. The authors come to some interesting conclusions about what really matters in parenting. Kids tend to get higher test scores if their parents are highly educated: because these parents have higher IQs and IQ is strongly hereditary. Children of mothers over thirty tend to do better in school. These women tend to be better educated or career oriented. Children whose parents speak English at home have better test scores. Conversely, adopted children do worse on tests, because adopted kids are most influenced by their biological parents' IQs; that are likely low. Reading to children doesn't improve test scores. However, children growing up in a house full of books do well in testing. Lots of books, mean high IQ parents.

The final chapter on naming children is the most fun. What's in a name? Nothing really. But, the speed at which children's names change and why is interesting and funny.

Freakonomics has been criticized for its controversial content, its lack of scholarly rigor, trivial subject matter and conclusions, and failure to expose the real economic damage done by government regulations and government granted monopolies. But, despite the flaws, I'm happy that a book of this subject matter is a bestseller.

One of my favorite parts of Rework (and that's saying something), is the section on hiring. The authors urge business owners to do a particular job first and then hire someone to do it. But only hire when it hurts, pass even when you can hire great talent, and only hire when you absolutely need someone. Hire slowly, otherwise you end up with a bunch of strangers. And résumés? What a joke. Why rely on a document that has been shotgunned out to hundreds of potential employers?
