I am grateful to my administrative assistants, Peri Doslu and Helga Bradish, for
expert support including library research, bibliographic work, and careful perusal
of the manuscript; to my daughter, Lisa Walford, for writing a portion of Chapter
8 and for her coverage of the menu items in the Appendix; again to Lisa Walford,
and to Karen McMann, for their respective roles (Karen as programmer) for the
software development so important in the genesis of Beyond the 120-Year Diet;
and to my editor, Kathryn Belden, at Four Walls Eight Windows, for useful sug-
gestions and careful editing. Finally, I acknowledge a debt to the useful and inter-
esting postings of the Internet Calorie Restriction Society (see Readings and
Resources, Internet Information Sources).
