Why do we help strangers? And why do we love revenge stories so much?  The same thing that connects those questions connects us all - bonding.

There’s an invisible line between groups of people - it can be a thin dotted line between acquaintances, a steel girder between mother and child, or a series of chain links between millions of people in the same country.

In Part 2 of this series on fate and biology, we identify the brain chemical that plays a central role in how we bond, and explore why certain group behaviors are inevitable.
