Check out this article. I believe this is the same guy who wrote about "Radical Honesty" that I talked about in this post. An "agnostic Jew", he spent an entire year living his life by the strict rules of the Bible. Some of it predictably improved his life (no gossiping for example), others un-predictably improved his life (he said he felt happier wearing all white clothing), and still others seemed to have a negligible impact (stoning adulterers).
If ever there was someone who could finally give you the religious equivalent of "I've used PC's for the last 15 years, and now I've switched to a Mac...and love it!", it's this guy.
I haven't read his book: The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible
