This is an absolutely fascinating book. I bought it yesterday, but didn't intend to read it right away as I'd just started the second book of the John Marsden "Ellie" trilogy. But I thought I'd just look at the first page and see if it was as interesting as the original "Freakonomics" book. That was at about 9:30 last night. Read steadily 'til midnight, and then finished it when I got home from work tonight. Takes all sorts of preconceptions and blows them away - well, some of them it blows away, others it shows are depressingly true.
