In 1999, the psychologists Robert Levine and Ara Norenzayan published a study of the pace of life in 31 countries in the Journal of Cross-Cultural Psychology.
They measured walking speed in city centers, the time a post office took to sell one stamp and the accuracy of 15 bank clocks in each country. Mexico came last of the 31 on the overall index. The authors called it “the archetypical land of a mañana.”
