Acknowledgments

I am grateful for the efforts by Joyce Martin and Brady Hamilton at the National Center for Health Statistics, to provide the data for this study. Thanks are also extended to Mary Snow Burnette and Regina Deal, for translating the article by Guillon et. al. I also thank Frederic Chambat for comments and suggestions.

On a personal note, I would like to express thanks for the births of my twins, Ashton and Celeste, for inspiring this investigation. (Yes, embarrassingly, they were born 5/31/91--
Gemini, The Twins).
