This Sunday marks the one-month anniversary of the death of Randy Pausch, author of the runaway bestseller "The Last Lecture." We hear from his co-author Jeffrey Zaslow in a new interview recorded since his friend's death. We also talk with best-selling novelist Dr. Robin Cook ("Coma") about his latest medical thriller, "Foreign Body." It concerns the increasingly common practice of Americans traveling to other countries like India to have complex surgical procedures done.
