This books provides the reader with answers to questions he might have always wondered about, but didn't know where or who to ask (or even to ask to at all!). David Feldman has written several other books of "Imponderables," which is actually a trademarked name for the types of questions posed in the book.
My favorite questions included What is the purpose of the orange balls on power lines, Why are there no photographs in the Wallstreet Journal, Why do eyes sometimes turn out read in pictures, Why do so few houses in the south have basements, Why is a piece of tissue paper included in wedding invitations, What function does the necktie serve, Why does soap yield white suds. How do kangaroos clean their pouches, Why does the groom carry the bride over the threshold.
This book is a great read. I would especially recommend keeping it in the bathroom, as it is an ideal book to read a page or two at a time.
