Join Rebecca, Heather, and Lora as they explore the mysterious North Sentinel Island in the Bay of Bengal, home to the Sentinelese people—one of the last uncontacted tribes on Earth.

For an estimated 60,000 years, this indigenous community has lived in complete isolation, fiercely protecting their island from outsiders. Discover why the Indian government has declared a 5-nautical-mile exclusion zone around the island, the rare (and often deadly) encounters with the outside world, and how the tribe miraculously survived the devastating 2004 tsunami.

From British kidnappings in the 1880s to a tragic missionary attempt in 2018, we examine the complex history of contact attempts and why leaving the Sentinelese alone isn't just respectful—it's essential for their survival. Plus, the hosts share their own travel adventures through Thailand and South America, complete with stories of helpful taxi drivers, chicken feet, and celebrating the 4th of July with British tourists.

Rebecca breaks down why these variations exist and what they reveal about local identity and language evolution, offering listeners a fun look at the quirks and diversity of English.
