Jacki recently filled us in on seven ways to add years to your life. Shape Magazine gives us some more tips -- this time from Dan Buettner's bestselling book, The Blue Zones. The author traveled around the world to areas known for the long life spans of residents. He observed the people's lifestyles and interviewed centenarians to develop his theories on living a long, full, healthy, and happy life. His tips are:

• Laugh. Laughing is an obvious sign of a good mood -- and it's widely accepted that your mood can affect your health. In addition, laughter can help relax blood vessels which may lead to a lowered risk of high blood pressure.
• Make exercise a part of your routine. The people Buettner interviewed weren't hard-core athletes. Instead, their daily lives were just filled with natural activities such as gardening and walking.
  
• Eat wisely. Enjoy your food and eat appropriate portions.
• Cultivate positive friendships. Choose friends who are supportive and are positive influences in your life.
  
• Live with intention. Find activities that make you happy and really live each moment.
