Did you see this in the news?
There are reportedly a few tribes in the Amazon ( approximately 100 worldwide) that have had no contact with current modern civilization. One report stated that is unlikely the tribes have never had outside contact, but rather previous contact was likely negative so the tribe has been driven further into isolation. It is a little mind blowing to think there are parts of the world that modern technology has not touched. I remember when I lived in Asia- the area of the world with the most 3rd world countries with the highest levels of poverty- and there was still modern technology present. I have a hard time imagining people who have never seen other humans from outside of their tribe.
That’s all. Just thought it was interesting.
