The proof for us is where we can fly, often for as little as $500 -$700 USD. Just about anywhere in Europe, Thailand, Vietnam, Singapore, China, even Australia.Although I enjoy reading about "small world" stories as much as anyone, I like the above post the best. I can fly from NY to Europe for not much more than NY to Columbus OH!! (but that's a different thread - FAA, are you listening?)
Amazing. Could imagine affordable travel like this 20 years ago. This, and the Internet is what has made our world seem much smaller.
But "small world" coincidences are not rare at all. For example, you only need a room of 23 people, to have a 50% chance that two people share the same birthday.
On the Oasis, assuming an average family size of three, there are 2 million "pairs" of families - a guarantee that somebody will know somebody!
