Touch frequency from country to country  Researcher  David J. Linden has just published a book called Touch, in which he examines the importance of physical contact, and cites a survey report by psychologist Sidney Jourard which found that couples sitting in coffee shops in San Juan, Puerto Rico touched each other an average of 180 times per hour, while couples in Paris touched 110 times, and in Gainesville, Florida, 2 times per hour. Couples in London didn't touch each other at all.

Doctor: Did you find that the patients in your study made a full recovery after surgery?

Researcher: Yes, they made an 80% recovery after just one year, but it took almost three years for them to make a 100% recovery. There was a non-linear progression in recovery levels.

Explanation:  The term “non-linear progression” means that the line in the graph is not straight. The rate of change is not constant.
