english: A few years ago, I came up with a way to study people's happiness moment to moment as they're going about their daily lives on a massive scale all over the world, something we'd never been able to do before. Called trackyourhappiness.org, it uses the iPhone to monitor people's happiness in real time.

Zove se trackyourhappiness.org, koristi iPhone da nadgleda ljudsku sreću u stvarnom vremenu.
