In the wake of several controversial rulings by the Supreme Court and the ongoing debate about how the Constitution should be interpreted, A.J. Jacobs set out to understand what it means to live by the Constitution. The book blends unforgettable adventures --- like delivering a handwritten petition to Congress and applying to become a legal pirate for the government --- with dozens of interviews from constitutional experts from both sides. Jacobs dives into originalism and living constitutionalism, the two rival ways of interpreting the document. As politicians and Supreme Court Justices wage a high-stakes battle over how literally we should interpret the Constitution, A.J. Jacobs provides an entertaining yet illuminating look into how this storied document fits into our democracy today.

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.
