There are still tribes living in Tanzania that are literally frozen in time.

The photo shows the Hadza people. In 2020, these people live in straw huts, make fire by rubbing wooden sticks together, and hunt for meat. They also speak only their own language (full of clicking sounds – even saying "hello" is hard to pronounce). And they don't know Swahili.

The tribe is aware of the civilized world's existence, and even buy flour with money from selling souvenirs when food gets really scarce. The turnover is minimal. And the souvenirs are basically craft project level.

The tribe is perfectly content with this lifestyle and flatly refuse to change anything.

PS. Before the trip, I honestly thought it was just a tourist attraction. But after being there, I can say with certainty that this is just how they live. No actor could pull it off.
