Things like big-footed modern-day barbarians and this time "lost Amazon tribe" are around in media reports. I don’t believe they are true or completely true even though they might appear in "mainstream" media outlets or are re-run in other equally "authoritative" ones.

We have to develop a sense of humor and have our own judgment when being inundated by  information. I had no proof they were just cooked up. But, the picture didn’t look to me more real than Hollywood movies. Also, I don’t believe there are any areas where non-barbarian humans cannot reach on Earth, especially where there are trees in the Amazon and where there are more than 90-percent-naked tribesmen.
