A new large-scale survey, conducted by American researchers, has revealed some interesting new statistics about our behaviour in relationships. The results of the online survey, which polled almost 100,000 people from around the world, were published a month or so back in a new book called The Normal Bar – a title which reflects the survey’s attempt to define ‘normal’ when it comes to sex, love and romance in society today. Among the survey’s findings was that maintaining a mood of romance is important for a successful long-term relationship.
