I seen on the news just now that a big survey has confirmed the theory of "The six degrees of seperation" is true. The small world experiment was carried out and it found that if you choose two random people from aywhere in the world, you will only have to link them through an average of 5.5 people to find them. For example, if you chose a man in ireland and a man in australia, the irish man would know a man, who knows a man, who knows a man, who knows a man, who knows a man, who knows the australian man. Hard to explain, but read more at:
