Everyone tickles, but no one talks about it. Sort of like the weather but opposite. This book will increase the talking. It describes the role of tickling in the lives of over 2,000 women from all over the world.

It compares different regions of the world for how ticklish women are, how often they are tickled, how much they like tickling, and who does the tickling. Some personality traits were found to be strongly related to ticklishness or enjoyment of being tickled.

For many women, tickling had important roles in bonding with their parents, children, childhood friends, lovers, and long-time husbands. There are also reports of unpleasant, unwanted, and abusive tickling.

Although the book is based on a scientific study, it is written for the general reader. It contains information about tickling that is interesting and socially important and information that is just interesting.

The general theme is that tickling was not forced on humans by some horrible ancestor or bad luck. Instead, it had a purpose that evolution recognized was socially useful and is still an important part of interpersonal relationships today.
