This was an extremely interesting read. Thank you for providing this information. I have known that tribes like existed like this exist still, and it is quite fascinating to me. However I didn’t know if this specific tribe.
I will give my thoughts on their survival techniques. Like others have said, it is likely they have mastered herbal remedies. Their immunity must be very high, especially if they eat animals raw. The fish for instance could have traveled from the Atlantic and brought remnants of our diseases, gradually making them immune before it passes over their way by air.
As for the tsunami, I would assume they have a safe zone underground, which I know probably sounds unlikely on an island, however our earth’s underground system is even more vast than above ground. Tunneling several hundred miles down below. That, or these beings are able to breathe underwater.
Very nice contribution friend, thanks for visiting my blog.
