We've come a long way from the time when Ugg would mutter inanities to Uggetta in the cave, present her with a wad of crushed up flowers and move in for the kiss- and if she resisted he would reach for his club, gives it the old 'knock on the head and drag away' routine. Nowadays, for example, we do all the inanities on dating websites or in noisy bars. The rules of romance and courting have been shifting rapidly in the last 50 years and now many people are so clueless as to what they are supposed to do that they're paying experts to teach them how to make that connection. Our expectations from marriage and our relationships are also different. How much has the nature of what is perceived as 'romantic' changed from the past? How much do we even know about what brought people together thousands of years ago?

Everyone makes them (some of us more compulsively than others): scribbled on post-it notes, or kept mentally in our imaginations – we all make lists. And we're not the only ones either; lists have been around for a long time – possibly since the first writing systems and certainly since Sumerian scribes began to keep accounts in the fourth millennium BC in Mesopotamia. So what is it about the beauty of a list – its numerical order, hierarchy, completeness – that makes them such a part of how we like to categorise, order and understand the world?
