Freakonomics by Steven D. Levitt and Stephen J. Dubner

Forgive me for just pasting my Bookcrossing entry here.

Finished this today. This was a quick read. It was a little more dry than I had anticipated, but still interesting if you're interested in quirky things like how much a child's name affects their success in life, or the inner circle of a group of drug dealers (much like a pyramid scheme).

Here's a part I thought was interesting:

It's true that more people die in the United States each year in motor vehicle accidents (roughly forty thousand) than in airplane crashes (fewer than one thousand). But it's also true that most people spend a lot more time in cars than in airplanes... The per-hour death rate of driving versus flying, however, is about equal. The two contraptions are equally likely (or, intruth, unlikely) to lead to death. -- page 151
