Bill’s initial idea was for me to write the lunettes Armani and he would serve as editor and agent (which he has done for several books by Phil Maffetone), but in our conversations we came up with a concept that was going to be more than I could handle on my own given time constraints associated with my sunglasses ray ban and being a father of three little kids. So, we agreed to co-author a book and divided up the topics that we wanted to hit upon.
