You also have the oasis theory that in some parts of the world in the Middle East that there was only so many pockets of water of oasis that was available which caused the hunter and gathering people to come together and sit down. But geographically we're located in the Middle East, in Syria, in the Far East, in China and as these changes occur they will begin to kind of like ripples in a pond kind of you know reverberate across Europe and then in Africa and then eventually making their way over to North America. But at the end of the day the biggest thing that you want to know for causes is that it's the end of the Ice Age and that it's going to cause people for the first time to figure out we need to sit down. And now that you sit down there's probably going to be some revolutionary changes that occur that we should look at right now. Right now. So number one is agriculture and of course it depended where you are of what you grew but in the beginning it's going to be single crop. They're going to have wheat in the Middle East and figs.
