From March 2012 until November 2012 I embarked on an improbably long cycling odyssey up the east coast of Australia, researching a book about simple living. You can follow the journey at www.simplelives.com.au. If you search the site hard enough, you might even find photos of me naked. (Unlike my self portrait, these pictures aren’t in the least bit flattering.) The book, titled Changing Gears, will be published in September 2013.
