North Sentinel Island: Natives of Neverland

Apparently, there's this island right in the Bay of India that has these natives that are one of the last uncontacted tribes on the planet. They've been there for over 40,000 years and are openly hostile to outsiders (and known to kill). The Indian government actively patrols around the island to prevent anyone from making contact. I'm awe-struck seeing a culture so well-preserved in a global modern era.
