So apparently this is a thing, the UP Series idea applied to South Africa. If you aren’t familiar with Michael Apted’s UP Series I’d highly recommend it. Apted has been producing documentaries about the same group of people every seven years since they were 7 years old. The series is currently at 56 up, and Apted (age 72) says there will be a 63 Up if he is still alive to make it in 2019. The UP Series (aside from the latest 56 up) is currently on Netflix streaming, so go watch it!
Unfortunately Netflix only has 21 Up South Africa so I’m going to have to find it elsewhere.
