Maybe because I was raised in a very middle class family in a very domesticated setting so it's the absolute opposite of what I knew growing up, but I'm obsessed with reading about cultures who have little or no connection to our world.
Like this group of people, they would probably get sick if they tried to join our society. An explorer actually brought some of them back to the mainland (aka kidnapped them, by the sounds of it) to study them, and they got really ill and died. And they shoot arrows at anyone who tries to approach the island (and they killed a missionary who thought he somehow deserved to ignore all the rules and warnings to teach them about religion).
Omg this sounds absolutely up my alley! I usually don't get too into the true crime stuff but if there's a strange mystery or a lot of weird circumstances I'll give it an evening.
