I have loved archaeology since middle school and have spent many vacations dragging my wife and kids around the world visiting ancient ruins—from the Anasazi kivas of the American Southwest to the “lost cities” of Machu Picchu and Petra to the big-headed Moai statues towering over Easter Island. Somewhere along the way, medical school and a neurology residency derailed my affair with the subject. But even now I sometimes imagine myself as a brain archaeologist—delicately picking through preserved specimens, cataloguing biological artifacts and trying to align my findings with people's unique histories.
