I want to express my most profound appreciation to my parents, as their unceasing support above and beyond the parental call of duty brings me to tears. I am grateful to my father, Leonard Abrams, who taught me how to write, and to my mother, Marilyn Abrams, who taught me mathematics. I express my deep gratitude to my wife, Cindy, who believes in me, and to my children, Yonatan, Binyamin, Miriam, Nechamah, and Rivkah, who gave up countless Sundays with me for this book.
