As I said on Saturday, when I began watching the Blue Zones docuseries, I would have wagered that either nutrition or exercise would be the most important factor in living longer. What we eat and how much we move are important, but the key to living well to 100 are the interactions we have with people.

That can take many forms. Your spouse can be the most important person you interact with along with family members who live close by: grandparents, parents, children, grandchildren, aunts, uncles, and cousins, can all be part of your social group. Business groups such as Toastmasters and Chamber of Commerce, fraternal and sororal organizations, volunteer groups, and church groups all add to your social circle. An unstructured group that gets together to have coffee, make cookies, or play cards can also provide social interaction.

It’s more difficult in much of the world today because families often spread out due to school and jobs. Families may see each other during holidays but don’t have the frequent personal interactions that provide a support network. COVID also interfered with our ability to socialize; once regular social interaction was blocked, sometimes it never came back. Research has shown that the isolation was devastating to many. The governments of Japan and the UK were so concerned, they appointed Ministers of Loneliness.

I don’t have answers to how you increase your social interactions other than to seek them out; Facebook and texting are better than nothing, but being together is better. So my challenge to you is to take action to reconnect with friends and family:

• Join a club or create one of your own, like a neighborhood walking group
• Make a lunch date with someone you haven’t seen in a while
• Call a friend in another city or state to catch up
• Invite the neighbors over for dinner
• When someone invites you to go to a movie or to meet for a drink after work, find a way to say yes

You may find that a few relationships can’t be rekindled, but you also may find yourself with a more stimulating social life—and that’s good for your health. I do know that if you want to live well to 100, social interaction is the most important lesson from the Blue Zones series. I’ll give you my final thoughts on Saturday.

Tomorrow night is the Insider conference call. There’s some interesting research I’ll share as well as answer Insider questions. Become an Insider by 8 p.m. tomorrow night and you can join in.

What are you prepared to do today?
