A.J. Jacobs tries to get inside the minds of the Founding Fathers by living as closely as possible to the original meaning of the Constitution. He asserts his right to free speech by writing his opinions on parchment with a quill and handing them out to strangers in Times Square. He consents to quartering a soldier, as is his Third Amendment right. He turns his home into a traditional 1790s household by lighting candles instead of using electricity, boiling mutton, and --- because women were not allowed to sign contracts --- feebly attempting to take over his wife’s day job, which involves a lot of contract negotiations. The book blends unforgettable adventures --- delivering a handwritten petition to Congress, battling redcoats as part of a Revolutionary War reenactment group --- with dozens of interviews from constitutional experts from both sides.

What makes puzzles --- jigsaws, mazes, riddles, sudokus --- so satisfying? A.J. Jacobs --- New York Times bestselling author, master of immersion journalism and nightly crossworder ---- set out to determine their myriad benefits. And maybe, in the process, solve the puzzle of our very existence. Well, almost. In THE PUZZLER, Jacobs meets the most zealous devotees, enters (sometimes with his family in tow) any puzzle competition that will have him, unpacks the history of the most popular puzzles, and aims to solve the most impossible head-scratchers, from a mutant Rubik’s Cube, to the hardest corn maze in America, to the most sadistic jigsaw.

Author A.J. Jacobs discovers that his coffee --- and every other item in our lives --- would not be possible without hundreds of people we usually take for granted: farmers, chemists, artists, presidents, truckers, mechanics, biologists, miners, smugglers and goatherds. By thanking these people face to face, Jacobs finds some much-needed brightness in his life. Gratitude does not come naturally to Jacobs --- his disposition is more Larry David than Tom Hanks --- but he sets off on the journey on a dare from his son. And by the end, it’s clear to him that scientific research on gratitude is true. Gratitude’s benefits are legion: It improves compassion, heals your body and helps battle depression.

A.J. Jacobs has received some strange emails over the years, but this note was perhaps the strangest: “You don’t know me, but I’m your eighth cousin. And we have over 80,000 relatives of yours in our database.” Who are these people, he wondered, and how do I find them? So began A.J.’s three-year adventure to help build the biggest family tree in history. His journey would take him to all seven continents. He drank beer with a US president, found himself singing with the Mormon Tabernacle Choir, and unearthed genetic links to Hollywood actresses and real-life scoundrels. After all, we can choose our friends, but not our family.
