You may know A.J. Jacobs as the man who attempted to read the Encyclopedia Britannica from cover-to-cover. Or you may have been introduced to him when he spent a year trying to follow the Bible as literally as possible. He returns once again with another seemingly impossible task--that of becoming the healthiest man alive. As with his earlier books, Jacobs brings his quick wit, self-deprecating humor, and journalistic eye to the experiment. He leaves no health stone unturned: from literally running his errands and wearing noise-cancelling headphones for hours a day to rigging a desk that he can work at while walking on the treadmill (there are instructions at the end for those interested), Jacobs chronicles the good, bad, and ugly of trying to attain “perfect” health. Jacobs’ writing is breezy, informational, and entertaining, and he manages to achieve the near impossible--discussing issues of health without sounding preachy
