Note: I realize that I reference scientific studies an awful lot for someone who claims to not understand or care about science... but this is fascinating stuff.
Research shows two connections between eating chocolate and falling in love.
First, studies have found that falling in love may be less about EMOTION and more about motivation and drive. All the women out there are probably excited to hear this. We aren't merely big bunches of emotion when it comes to romantic pursuit. We are motivated and driven to be equally and perfectly matched.
Eating chocolate, often the result of a craving, is all about a motivation to satisfy and a drive to fulfill a need. It makes perfect sense to me since the object of both actions is all about obtaining pleasure and pursuing happiness. Which leads us to the second finding...
In many studies the act of eating chocolate and the act of falling in love showed similarities to Obsessive-Compulsive Disorder (OCD). No further explanation needed.
