Lessons for living longer from the people who've lived the longest --Lesson 9: Right Tribe

Be surrounded by those who share Blue Zone values

Higher social connectedness led to greater longevity. The type of social connectedness was not important in relation to longevity - as long as there was connection. Even a lack of a spouse or significant other could be compensated for by other forms of connection.

Lesson nine strategies

Identify your inner circle

Know the people who reinforce the right habits, people who understand or live by Blue Zone secrets. Go through your address book or your contact list of friends, Think about which ones support healthy habits and challenge you mentally, and which ones you can truly rely on in case of need. Put a "BZ" by their names, Ideally, family members are the first names on that list.

Be likable

Of the centenarians interviewed, there wasn't a grump in the bunch. Some people are born popular, and people are naturally drawn to them. Likeable old people are more likely to have a social network, frequent visitors, and de facto caregivers. They seem to experience less stress and live purposeful lives.

Create time together

Spend at least 30 minutes a day with members of your inner circle. Establish a regular time to meet or share a meal together. Take a daily walk. Building a strong friendship requires some effort, but it is an investment that can pay back handsomely in added years.
