Columnist's full book has wit and some advice

In his compilation of articles from his Wall Street Journal column, "Ask Ariely", Dan Ariely wraps in a clever bow all the questions we've ever wanted answered concerning the behavioral intricacies that dictate the decisions we make.

He offers extremely practical advice, like baby-sitting friends' children for an entire week to better estimate the costs and benefits of having children, in addition to brain-stretching teasers like how to choose the least used bathroom stall (it's the one furthest from the door).

As always, Ariely's intelligence is swathed in humility and charm. Bolstering his already likable writing style are cartoons by the talented William Haefeli, which help to humorously drive home Ariely's points.
