Back in the 1960s, a Harvard graduate student made a landmark discovery about anger.
At age 34, Jean Briggs traveled above the Arctic Circle and lived out on the tundra for 17 months. There were no roads, no heating systems, no grocery stores. Winter temperatures could easily dip below minus 40 degrees Fahrenheit.
Briggs persuaded an Inuit family to "adopt" her and "try to keep her alive," as the anthropologist wrote in 1970.
This story is part of a series from NPR's Science desk called The Other Side of Anger. There's no question we are in angry times. It's in our politics, our schools and homes. Anger can be a destructive emotion, but it can also be a positive force.

At the time, many Inuit families lived similar to the way their ancestors had for thousands of years. They built igloos in the winter and tents in the summer. "And we ate only what the animals provided, such as fish, seal and caribou," says Myna Ishulutak, a film producer and language teacher who lived a similar lifestyle as a young girl.
Briggs quickly realized something remarkable was going on in these families: The adults had an extraordinary ability to control their anger.
"They never acted in anger toward me, although they were angry with me an awful lot," Briggs told the Canadian Broadcasting Corp. in an interview.
