**Unveiling the Secrets to Living a Century: Insights from Centenarians**
Reaching the age of 100 is a remarkable milestone that only a small percentage of the population achieves. Centenarians—those who have lived for a century or more—offer a unique window into the secrets of longevity. Their lives are a testament to resilience, adaptability, and the interplay of genetics, lifestyle, and mindset. But what exactly are the factors that contribute to such a long and fulfilling life? Let’s explore the insights shared by centenarians and the science behind their extraordinary longevity.

### **1. The Role of Genetics: A Strong Foundation**
One of the most significant factors influencing longevity is genetics. Studies have shown that centenarians often come from families with a history of long-lived relatives. Certain genetic markers, such as those associated with efficient DNA repair and reduced inflammation, are more common in people who live to 100 or beyond. However, while genetics provide a strong foundation, they are not the sole determinant of longevity. Experts estimate that genetics account for only about 20-30% of a person’s lifespan, leaving lifestyle and environmental factors to play a much larger role.

Centenarians often emphasize the importance of a healthy, balanced diet. Many follow dietary patterns similar to the Mediterranean or Blue Zone diets, which are rich in fruits, vegetables, whole grains, nuts, and healthy fats like olive oil. These diets are low in processed foods, sugar, and red meat, which are linked to chronic diseases.
For example, in Okinawa, Japan—home to one of the highest concentrations of centenarians in the world—residents follow a plant-based diet that includes sweet potatoes, tofu, seaweed, and green tea. They also practice “hara hachi bu,” a Confucian teaching that encourages eating until you are 80% full, which helps prevent overeating and promotes a healthy weight.

Physical activity is a common thread among centenarians. However, this doesn’t necessarily mean intense workouts or gym sessions. Many centenarians engage in moderate, consistent physical activity as part of their daily routines. Gardening, walking, dancing, and even household chores keep them moving and maintain their strength, flexibility, and cardiovascular health.
In Sardinia, Italy—another Blue Zone region—shepherds often walk long distances across hilly terrain, which contributes to their exceptional fitness levels. Regular movement not only keeps the body healthy but also reduces stress and improves mental well-being.

Mental and emotional health play a crucial role in longevity. Centenarians often exhibit a positive outlook on life, resilience in the face of challenges, and a strong sense of purpose. Studies have shown that optimism and emotional well-being are linked to lower levels
