Timothy Ferriss "The 4-Hour Body"

Timothy Ferris authored one of my favorite books, "The 4-Hour Hour Workweek" a few years ago...and now he just released "The 4 Hour Body".  He used himself as a guinea pig over the last few years and has published the results.  He covers everything from sex to diet to sleep to working out, and more.  At the end of this conversation he also divulges his unique way of using music when writing.
