Obviously KK you don't understand the deeper meaning of Fox's post. There are 4.7 billion people living on Earth. He didn't bother to mention the other 2.3 billion people alive but not really living. You know the type don't you? Oh hang on.....someone just died. It was on the news. That's minus 1. Wait, someone has just had a baby. That +1. Good, we're back to 7 billion. Better go now as whoever is keeping track of this has a difficult job. Too difficult for me.
