ACKNOWLEDGMENTS

Heartfelt thanks to friends who drew even closer after Paul’s stroke, especially Dava, Peggy, Jeanne, Dan, and Philip. Continued thanks to Alane Salierno Mason, my smart and savvy editor at Norton, for her encouragement and guidance. Jeanette Norden, director of the Brain and Behavior Module at Vanderbilt University, brought her expert eye and welcome insights. Dr. Ann’s medical knowhow and generosity of spirit were a godsend. And I’m indebted to Paul and Liz, who read and listened to the manuscript in its many revisions, sharing invaluable memories, corrections, and suggestions. In Rashômon fashion, we’ve all experienced the same events, though from different angles.
