Tim Ferriss - author, podcaster, self-experimenter
Tim Ferriss and I sat down recently for a long and fascinating conversation. Ferriss, a modern day self-help guru, is the author of The 4-Hour Workweek, The 4-Hour Body, The 4-Hour Chef and now a new giant of a book, Tools of Titans. We cover everything from the power of fasting to the power of choosing the right friends, his obsession with self-experimentation and learning from the world's highest achievers. This is a long version of the interview which first aired, in edited form, on BBC Radio 5 Live.
