Dan Buettner explores the world's Blue Zones and researches longevity as a writer for National Geographic magazine.

As the author "The Blue Zones: Lessons for Living Longer from the People who have Lived the Longest," Buettner shares his thoughts about the link between longevity and the rather basic diet of the people of Sardinia.

The Sardinian diet is heavy on bread, cheese and very dark red wine.  Meats are consumed infrequently and fish is relatively unimportant.  Nuts, fruits and vegetables are emphasized.

Albert Lea Minnesota might very well turn out to be a newly discovered Blue Zone.

Twenty percent of Albert Lea's residents have begun to adhere to a set of activities and habits geared towards increasing longevity.

Common practices include:

• Eating a healthy, plant-based diet.
• Maintaining an active lifestyle.
• Developing a clear sense of purpose.
• Sustaining strong social networks.
