The Know-It-All: One Man's Humble Quest to Become the Smartest Person in the World. What really defines intelligence? Book smarts? Street smarts? Problem solving smarts?
An interesting look at what A.J. learns about the world, and himself, as we reads through the entire Encyclopedia Britanica. Woven between random facts - The serrated edges on coins were created as a deterant to criminals who shave the metals off old coin - he shares stories of how what he is learning is impacting his life, in good ways and bad. At times humorous, he is more likely to remember the odd and off-kilter facts, as opposed to tiny rivers in Namibia. Making it both an educational and enjoyable read.
(I also highly recommend another book by A.J. Jacobs, The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible)
