How To Cut Your Own or Anybody Else's Hair by Bob Bent. This was indeed useful -- apparently the key to cutting your own hair is to cut a guide section in front and then match all the other hair up to that section, using lots of mirrors to see the back. I'm pretty sure you couldn't do a complicated style in this manner, but I expect it would work for a simple style if you could stand a few weeks of wearing the results of your own practice.
Sadly some jerk decided to cut out the section on how to cut straight kid's hair (the straight hair of a kid, not the hair of a straight kid -- we don't know about that yet), which is of course the one thing I really wanted the book for.
On Bullshit by Harry G. Frankfurt. Of the three bullshit books I have recently read, this is by far the most successful, with a very intriguing conclusion.
The Curse of the Narrows: The Halifax Explosion 1917 by Laura MacDonald. I love a good disaster book, and this is a good disaster book. I think I would have enjoyed it more if I had not tried to read it on vacation, surrounded by a million distractions.
False Alarm: The Truth About the Epidemic of Fear by Marc Siegel approaches the current American state of constant panic from a more medical point of view. I don't know if it's just me, or if it's all of Canada, but I don't experience the kind of constant fear that he talks about, and I don't really know anyone who does.
The Undercover Economist: Exposing Why the Rich are Rich, the Poor are Poor--and Why You Can Never Buy a Decent Used Car! by Tim Harford. This is a pretty interesting book about how economists think about stuff (much like Freakonomics, but slightly less amusing). Harford leans a little further to the right than I am used to, which got my back up a bit, but his arguments are convincing, so in the end I'm sure it did me good.
