I bought this book from Brotherhood Books and some kind previous reader had left a post-it note inside, saying This is a Good Read XY, and I certainly concur. AJ Jacobs is the kind of writer you'd love to go out for dinner with, he is wonderfully amusing and witty company.
Possibly my favourite chapter in this book was the last ('Whipped'), in which he puts himself in the hands of his long-suffering wife, Julie. AJ's expectation was that Julie would soon tire of being the boss of everything and welcome back his old self. Didn't happen. Julie relished being in total charge and dreaming up tasks for her husband to cheerfully perform, like foot rubs, sorting out the kids' toys, and doing all the daily shitwork that usually fell to her. Best. Experiment. Ever!! Maybe I'll try it out myself.
AJ Jacobs has a new book out, The Puzzler, and I'm looking forward to reading it.
