NTM PNG just made a new video looking into why we spend the time learning tribal languages. It features a few clips from Kovol, check it out:
I went over to Kavaluku and borrowed his machete thinking that I'd cut the snake's head off just in case it still had some life in it! I raised the machete and swung and struck true, catching it full force on its skull. At that point, I realised it was very much a live snake as it thrashed around! I find it amazing that I didn't miss my mark, my aim is usually terrible!
