What habits do the world's oldest people have that help them live so long and healthily?

Recently, the world bid farewell to Maria Branyas Morera, who, at 116 years old, held the title of the world’s oldest living person. Her passing marks the end of an era, but it also sparks a certain curiosity: what habits allowed her and others like her to reach such incredible ages?

To answer this question, let's take a short tour. From the sunny shores of Okinawa to the quiet towns of Sardinia, certain communities are known for producing an unusual number of centenarians — people who live to be 100 years old or more. These "Blue Zones" hold the secrets to a longer, healthier life, distilled into what Emmy-award winning researcher Dan Buettner calls the "Power 9." Let’s dive into these nine habits that could be your ticket to living a life that’s not just long, but full of vitality.

1. You Gotta Move It, Move It

Forget the gym membership or the marathon training. The world’s oldest people have never heard of CrossFit, and yet, they move constantly. How? By integrating movement into their daily routines. Whether it’s gardening, walking to the market, or dancing to their favourite tunes, these centenarians keep their bodies in motion without ever stepping foot on a treadmill.

2. Know Your “Why”

In Okinawa, they call it “ikigai”; in Nicoya, Costa Rica, it’s “plan de vida.” These terms translate to something more profound than just a job or a daily grind — they represent a deep-seated purpose that gets you out of bed every morning. Whether it’s taking care of family, volunteering, or simply enjoying life’s small pleasures, knowing your "why" could add years to your life.

3. Relax, It’s Happy Hour Somewhere

Stress is inevitable, but chronic stress is not. The longest-living people in the world have all figured out how to downshift — whether it’s through daily naps, a moment of prayer, or a glass of wine at sunset. These simple rituals are as effective as they are enjoyable, helping to reduce inflammation and stave off age-related diseases.

4. Eat Until You’re Almost Full

In a world of supersized meals and never-ending buffets, the 80% rule stands out like a beacon of common sense. Known as “hara hachi bu” in Okinawa, this practice involves stopping eating when you’re about 80% full. It’s a simple way to prevent overeating and maintain a healthy weight — two factors that are key to longevity.

5. Beans, Greens, and Everything in Between

If you want to live long, it might be time to rethink your relationship with meat. In Blue Zones, the diet is predominantly plant-based, with beans, lentils, and vegetables forming the cornerstone of most meals. Meat, when it is consumed, is more of a side note than the main event.

6. Drink to Your Health — Literally

Yes, even wine makes the list. But before you pop that cork, remember that moderation is key. The world’s oldest people drink one to two glasses a day, often in the company of friends or with a meal. This isn’t about getting tipsy; it’s about enjoying the moment and reaping the benefits of a little bit of red wine on your heart.

However, it may be important to know that scientific consensus still remains mixed on the matter. Some researchers assert that drinking in moderation can help with overall well-being, while others (and the World Health Organization) vehement that there is no “safe amount” to drink everyday.

7. Find Your Tribe

There’s a reason why social media can’t replace face-to-face interaction. In Blue Zones, Dan explains that being part of a faith-based or community group is common in these parts, alleging that research has shown that attending services or gatherings regularly can add up to 14 years to your life.

8. Family Matters

Family is not just about who you’re related to by blood. In Blue Zones, centenarians often live with or near their families, taking care of one another in a way that strengthens emotional bonds and lowers disease rates. They commit to life partners and invest time in their children and grandchildren, ensuring that love and care flow both ways.

9. You Are the Company You Keep

Ever heard the saying that you’re the average of the five people you spend the most time with? It’s especially true when it comes to longevity. In places like Okinawa, people form lifelong bonds with a close-knit group of friends — these relationships provide emotional support and encourage healthy behaviours, making them a key ingredient in the recipe for a long life.
