Co-authored by entrepreneur Chrisanna Northrupp, sociologist Professor Pepper Schwartz, and Director of the Centre for Social Science Research at George Mason University in Virginia, Professor James Schwartz, the book uses data collected from an ongoing global online survey, and gives an insight into modern attitudes to sex, love and relationships.
The Washington Post reveals that 74 per cent are content in their current relationship, with a lucky 66 per cent believing their partner is their soulmate.
One possibly surprising revelation is that men tend towards a more romantic view of love, with 48 per cent claiming to have fallen head over heels at first sight. Only 28 per cent of women could say the same.
For those hoping to keep love alive though, it seems the answer could be in the little things. The book claims that for many, the secret to a happy relationship is having regular date nights, using pet names for your loved one, holding hands, kissing, offering the odd back rub and saying 'I love you' on a regular basis.
According to the results of the survey, a lack of communication was the number one reason for the breakdown of a relationship - so while romance and passion are all very well, it seems the simple act of talking is the key.
