نبذه عن الكتاب: am grateful to the many other people who did not discard the e-mails asking them for help. Dr. Jon Walters, a physician who doubles as a home makeover expert, seemed to find time to read as he drove from Pittsburgh to Cleveland and back again to teach us how to make the metaphors appropriate for both the home repairman and the health care professional (if you were driven off the road between Pittsburgh and Cleveland, blame us). He also contributed significantly to the science, especially in the sex chapter. The family trio of Dr. Axel Goetz, Anka Goetz, and Margarthe Goetz also merits special thanks for their critical review of the science, the artistry, and the style of the book chapter by chapter. I also want to thank Debbie Schwinn, MD, PhD, of Duke; Jeff Watson, DDS; John Hoepner, MD; John Vasselli; John Campodonico; Sydney Unobskey; Jim Graham; Chas Brendler, MD; Roz Wattell; Marcie Anthone; Kandi Amelon; Jennifer Plant; Linda DeFrancisco; and Irwin Davis, who each took red pen to more than one chapter. Ruth Klein made the diet chapter easier to follow with her revisions. I also need to thank Tracy Hafen, who taught me a magnificent amount about exercise; Sukie Miller and Anita Shreve, for saying the early chapters were just what she wanted to read; the many gerontologists and internists who read sections of the book for accuracy; others on the RealAge team who validate and verify the content, and contributed their expertise to the book, including the many who contributed recipes, such as Rich Tramonte and Gale Gand of Tru in Chicago; John La Puma, who taught me an amazing amount about cooking and nutrition, and collaboration; the staff of Rick Bayless’s restaurants, Dan Zakri, and the chefs at the Kendall College of Nutrition in Chicago, who created many of the recipes; Shivani Chadha and Kate Poneta, the research associates who worked tirelessly to analyze the nutrients and calculate the RealAge effect of each recipe; especially Donna Szymanski (she must have incredible patience—she taught me how to cook and she cooked every recipe we tested—over 350—at least three times); and our tasters, especially the Wattels of Lettuce Entertain You.
