Correlation between Feelings and Chocolate

When I use to study Statistics (which by the way, I enjoyed thoroughly),often there was a word reused in that class "Correlation". That word and its function used to intrigue me and I often thought whether this may ever be used in the real world. Well, It is used everywhere we just fail to realize it. For instance, There is a correlation between almost everything, point at anything and you will  see its correlation with something else, just have to concentrate.

Why am I discussing such a boring word, well..Today, I was feeling...Joyless. It has a reason. My better half (actually my better whole) is out of the country and wont be here on his birthday perhaps that made my day and activities half-hearted, I literally felt no enthusiasm and my day was basically very unproductive and sluggish till I decided to do something which might cheer me up. The first thought that came to mind was...CHOCOLATE CAKE..

I'm not a chocoholic, but chocolate chip ice cream and chocolate cake is my BFF. So after much debating, I decided to treat myself with a molten lava chocolate cake and there I was baking myself a delectable cake. After eating half of its batter and then finally baking it, I asked myself whats the correlation between feelings and chocolate? I often saw friends craving for chocolate when they are specially down or stressed about something. I also remember eating a bucket full of Ben n Jerry's chocolate ice cream when studying for Accounting exams in order to motivate myself.

What's the psychological correlation between emotions and cravings for chocolate. Another thing I'd like to add is we often never crave for chocolate when we are rather happy. That's weird.

Any way, Happy eating to me and happy reading to you
