Anthony Bourdain's return after 10 years felt like an emotional journey as he had a deep connection to the indigenous people and culture of Borneo. The Ibans were head hunters (not the kind that calls you for an available job but the kind that chops off your head).
There is also a movie by Jessica Alba on the Ibans of Sarawak, called The Sleeping Dictionary. Its a fictional fantasy and romance in the 50's , but based on actual cultural practices of Ibans during the British occupation.
In this video, Anthony Bourdain seemed like he was tracing back his steps to all the places he has been to, and the people he has met. Maybe it was his way of saying goodbye
