The terms "centenarian" and "supercentenarian," which have found their place in dictionaries as translations, refer respectively to individuals who have completed 100 and 110 years of age. Today, there are more than 500,000 centenarians in the world, and this number is estimated to reach millions by 2050. Centenarian and supercentenarian individuals are of considerable interest to the scientific community, as they likely hold valuable clues about human health within their bodies.

A long life is the dream of most people. In this regard, supercentenarians—individuals over 110 years old who continue to live in good health—attract not only the attention of the scientific world but also that of all humanity.

In the 15th century, the average human lifespan was about 35 years. This situation was directly related to frequent child mortality and inadequate healthcare in those times. Today, approximately 500 supercentenarian individuals are known to be living. These people, who have passed 110 years and continue to live healthily, have become the focal point of the medical world. The curiosity created by increasing life expectancy leads to many questions about the lifestyles of supercentenarian individuals.

It is possible to list some known common characteristics of supercentenarian individuals as follows:

Most have never smoked throughout their lives.
Cigarettes contain approximately 5,000 different substances that are carcinogenic and toxic. The harm they cause to human health is countless and obvious beyond explanation. When looking at supercentenarian individuals, many are observed to have never used cigarettes throughout their lives.

They consume alcohol in a controlled manner.
Frequent and excessive alcohol consumption causes permanent damage to brain function and the cardiovascular system. There is no compelling research showing that alcohol consumed in moderation and for social purposes has negative effects on human health. On the other hand, there are current field survey studies suggesting that low to moderate alcohol consumption has positive effects.

They eat healthily and do not neglect exercise.
Another common characteristic of supercentenarian individuals is that none of them are obese. In fact, they are quite fit. It is a known fact that obese individuals live much shorter lives than those at ideal weight. According to research, while the average lifespan of people who are slightly overweight shortens by 1 year, those who are significantly overweight may see this reduction extend to 10 years.

It is also known that supercentenarians eat a vegetable-based diet and never neglect exercise. In addition to adequate and balanced nutrition, exercise is essential for a healthy lifestyle.

They live stress-free lives.
Intense and uncontrolled stress eventually leads to numerous psychological and physiological problems. Supercentenarian individuals are quite skilled at managing and coping with stress. As a result, their chances of developing chronic diseases are greatly reduced, and a significant portion of the conditions necessary for a long life are met.
