A. J. Jacobs is a New York-based journalist who works for Esquire magazine and specializes in immersing himself in odd, demanding projects and then writing about it. Jacobs spent a year reading all 32 volumes of the Encyclopedia Britannica (resulting in The Know-It-All) and later spent a month following the principles of the Radical Honesty movement (the article he wrote about this experience is entitled "I Think You're Fat", which should give you an idea) . His latest project was to follow all the rules of the Bible for a full year, which he then documented in his book The Year of Living Biblically. In the talk embedded below (or click here) Jacobs describes his year as a fundamentalist and then draws a bunch of interesting lessons. It's well worth watching, not least because it's screamingly funny.
