I don't know if you have access to this material from where you are reading this - most of you that visit this blog are from Estonia, US and United Kingdom - but if you can, please watch this documentary.

It is a documentary (or to be exact, a series of several episodes) recently made and broadcast in New Zealand, and it's about a so-called longitudinal "Dunedin study" where a team of researchers have tracked over a 1,000 people that were born in Dunedin, New Zealand in 1972, to find out how these people have changed over the years and what has affected what kind of adults they've become.
It has shown links between children's self control and their expected employment opportunities as adults, how people chose their partners, and even how as preschoolers, as young as 3 years old, it could've been forecasted which of these children were going to end up in jail as adults.
Fascinating, and at times a scary documentary to watch. Both myself and The Man teared up at several moments.
An article at www.stuff.co.nz/entertainment/tv-radio/80355634/why-am-i-sheds-light-on-the-internationally-renowned-dunedin-study explains the gist of the series and it's a wonderful, wonderful documentary to watch.
PS. When I read that the participants of this study were born at the Queen Mary Hospital in Dunedin, I cannot help but remember that The Kid, too, was born in Dunedin. That's where we spent our first 2.5 weeks together.
