In extreme cases they call out the cavalry. Might be the SWAT team, Navy Seals, perhaps Ninja. Pirates, ghosts, monsters or aliens, sounds like movies doesn't it?
In modern times, we have drones, stun guns, lasers and weapons of mass destruction. We have motion cameras, satellite vision, infrared cameras, night vision goggles. People can feel safe and secure almost anywhere on the planet. Anywhere except one place!
The place is called North Sentinel Island. An island the size of Manhattan lying in the Indian Ocean.
A place where 400 natives reside. Who speak a language no outsider has ever translated. They wear no clothes and if you visit this island, they'll kill you with bow and arrows and/or spears. Sounds crazy this being 2013, but it's completely true.
The island is surrounded by a reef, a perimeter of beach and a complete coverage of trees everywhere else. No one knows how they live, specifically where they sleep, basically nothing about them! There was some video on the internet from a few years ago to wet your whistle. There are some first hand stories that add some further perspective. However you would not want them as neighbors.
So, you went through another routine day. Your mentality stayed consistent. You dreamed again of winning the lottery. You went to bed. You never heard of the North Sentinelese tribe, had absolutely no clue. So I ask you, what else is out there in the world? The possibilities for you to discover are endless.
Ironically, they can and will kill you and those people would die if man would come into contact with them (western diseases). They go back a long, long way. Marco Polo spoke of them. There's even talk of placing them undisturbed on that island around the year 2 AC.
You're here and they're there and even though it's the same planet- civilizations away. Today the world is smaller through telecommunications, except on one island! Maybe Amelia Earhart was there or Jimmy Hoffa, DB Cooper...Today you'll most likely be comfortable again with your surroundings, so will they. I wonder- which one will see it, as a beautiful day ….
