Centenarians, particularly those who live beyond 100 years, have been the subject of extensive study to understand the factors contributing to their longevity. While individual circumstances vary, there are several common traits and lifestyle factors that have been identified among those who live to 100 years or more, especially men. Here’s what science knows:

1. Genetics
   Strong genetic factors: Longevity often runs in families. Studies have shown that centenarians are more likely to have siblings or parents who also lived long lives. Specific genes, such as those involved in DNA repair, cholesterol metabolism, and inflammation regulation, have been associated with longer lifespans.

2. Diet and Nutrition
   Moderation in diet: Many centenarians follow diets that are moderate in calories. This is often linked to intermittent fasting or eating patterns that avoid overeating.

Plant-based diets: A significant number of centenarians consume diets rich in vegetables, fruits, legumes, and whole grains. For example, the Mediterranean diet, rich in healthy fats like olive oil and fish, and the Okinawan diet, which is high in sweet potatoes and other vegetables, are common among long-lived populations.

Low meat consumption: Those who live longer tend to eat less red meat and more fish or plant-based proteins.

Minimal processed foods: Diets low in processed sugars and refined foods are common among centenarians.

1. Physical Activity
   Regular, moderate exercise: Many centenarians engage in consistent, moderate physical activity. This includes walking, gardening, or doing manual labor. The key is regular movement rather than intense exercise.
   Staying active: Physical activity throughout life, rather than in short bursts or only in younger years, is a common trait. The emphasis is on lifelong activity rather than just fitness in youth.

2. Mental and Social Well-being
   Strong social connections: Centenarians often have strong family ties, active social lives, and a sense of community. Loneliness and social isolation are less common in these populations.

Purpose and engagement: Having a sense of purpose, whether through work, hobbies, or social roles, is another common factor. Many centenarians remain mentally engaged in activities they find meaningful.

Stress management: Those who live longer often have effective coping mechanisms for dealing with stress. This can include positive attitudes, spirituality, meditation, or other stress-reducing practices.

1. Healthcare and Lifestyle Choices
   Non-smoking: Most centenarians are non-smokers or quit smoking early in life.

Moderate alcohol consumption: Some studies have found that moderate alcohol consumption, especially wine, can be a common trait among centenarians. However, this is typically in moderation.

Access to healthcare: Regular access to healthcare and early detection and management of diseases are important. This doesn’t necessarily mean high-tech medical interventions but includes basic medical care and preventative measures.

1. Environmental and Socioeconomic Factors
   Stable environments: Many centenarians live in environments with low pollution, good access to clean water, and sufficient nutrition.
   Rural vs. urban living: A significant number of centenarians live in rural areas with less exposure to the stresses of modern urban life. This might contribute to lower levels of chronic stress and better overall well-being.

2. Sleep and Rest
   Consistent sleep patterns: Good sleep hygiene and regular sleep patterns are common. Many centenarians have routines that allow them to get sufficient rest.

3. Disease Resistance
   Lower incidence of chronic diseases: Centenarians tend to have a lower incidence of chronic diseases such as heart disease, diabetes, and cancer. This may be due to a combination of genetic factors, lifestyle choices, and diet.

Conclusion
While no single factor guarantees longevity, the combination of genetics, lifestyle, diet, social connections, and environment plays a crucial role in reaching and exceeding 100 years of age. Men who live to 100 tend to share these traits, though individual variations exist. The key takeaway is that a balanced lifestyle, with attention to diet, physical activity, mental well-being, and social connections, seems to be a common thread among those who live long, healthy lives.
