If you're looking for some new cocktail conversation topics, check out The Unofficial U.S. Census: What the U.S. Doesn't Tell You, by Tom Haymann (Fawcett Columbine, $8.) It's packed with trivia, such as the sex lives of Americans.
According to the book, nearly half of the nation's 55.65-million married couples have been faithful.
Also, the typical faithful spouse is most likely to be female, white, less educated, live in the Midwest or New England and reside in a rural community.
