This reminds me of the 7 Up Series (https://en.wikipedia.org/wiki/Up_Series https://en.wikipedia.org/wiki/Up_Series), where the same people are interviewed every 7 years, starting about age 7. The director of that series is unfortunately quite heavyhanded in the questions he asks, but the project itself is quite interesting. Next episode will show in 2019, I believe.
