Averages involving 37

I've got this book that I bought at a garage sale some years ago, called American Averages: Amazing Facts of Everyday Life. (Authors Mike Feinsilber and William B. Mead; ISBN 0-385-15176-4.) It was 1980 by Dolphin Books, a division of Doubleday.

The book is just loaded with numbers about all kinds of things. Working men talk about work during 25% of their conversation. Among households that own US savings bonds, the average amount owned is $3500. 54% of public high school kids who take foreign languages take Spanish. Between the ages of 30 and 50, the average American eats about 10 tons of food.

There are around 1-2 dozen numbers on every page -- more on pages with tables -- and there are 395 pages.

I thought it might be interesting to see how many 37s there were in the book, so I scanned through the whole thing over Christmas vacation. As it turns out, it was kind of interesting to see how few 37s there are in the book. In fact, for a long time I thought the only factoid I would get was going to be "There is nothing average about the number 37." I didn't find my first 37 factoid until page 63. (By my estimate of how many numbers there were, that's 756-1512 numbers into the book.)

But I did end up with a fair amount in the end. Here they are. As you read these, remember the publication date of the book and the ephemeral nature of averages.
