On a serious note, if we’re into confusing correlation with causation, we could make a case for anything causing anything. Exactly one week ago, for example, I had a cup of tea when I woke up in the morning instead of my usual black coffee. And lo and behold, Eyjafjallajökull explodes. It would be remiss of me to ignore the manifest connection between these two events, and I have decided never to drink tea again.
