The original reality show, filmed in 1978, 12 adults and 3 children were chosen from around 1000 volunteers to live in the “iron age”, they lived this way for 1 year, fully immersed and living the life.
The nice thing is they weren’t in competition with each other, no one was “voted” off, they lived and worked together as if it were the iron age. It also interviewed the people some 30 years later and how it affected their lives.
Enjoy!
