Collecting information on thousands of children is a really powerful thing to do, because it means we can compare the ones who say, do well at school or end up healthy or happy or wealthy as adults, and the ones who struggle much more, and then we can sift through all the information we've collected and try to work out why their lives turned out different.
Prikupljanje podataka o tisućama djece uistinu je moćna stvar jer znači da možemo usporediti one koji su, npr. dobri učenici i koji na kraju budu sretni ili bogati odrasli ljudi i one koji se više muče i od toga možemo probirati prikupljene podatke i pokušati shvatiti zašto su naši životi drugačiji.
