“Some say that eating chocolate is better than kissing, and scientists have dutifully tested this hypothesis by carrying out a set of experiments. In 2007, a team led by Dr. David Lewis recruited pairs of passionate lovers, whose brain activity and heart rate were monitored first while they kissed each other and then while they ate chocolate (separately). The researchers found that although kissing set the heart pounding, the effect did not last as long as when the participants ate chocolate. The study also showed that when the chocolate started melting, all regions of the brain received a boost far more intense and longer lasting than the brain activity measured while kissing.”
