Total amount of money I spent on haircuts in 2008: $40.

(That's roughly $20/haircut. Which isn't to say that my hair was only cut twice in '08--just twice by professionals. During the summer, I shaved my head, a low-maintenance and low-cost luxury that I consider myself incredibly lucky to be able to take advantage of.)
