The quest for love: What makes people fall for one another?

What is love? It is perhaps the oldest and most fundamental question ever asked. Finding the answer became a real quest for Andela and Davor Rostuhar. After they got engaged, they set out to try to answer it by touring the world and meeting with couples from so many different communities, with so many different ideas about what the answer might be. In the end it was difficult to come up with a simple explanation, although they told us respect comes high on the list. Their work has been turned into a book and documentary entitled "Love around the World".
