Introduction
Determining who the oldest living human being is can be a difficult task, as many people have made claims of living for more than a century. However, to be considered the oldest living human, a person must have their age verified by reliable sources. This process involves meticulous research and investigation into the person’s birth and early life, as well as official documentation to confirm their age.
How to determine age
There are several methods used to verify the age of a person claiming to be the oldest living human being. These methods include birth records, census data, and personal identification documents such as passports and driver’s licenses. In some cases, researchers may also use DNA testing to confirm a person’s age. This method involves comparing a person’s DNA to that of their relatives, whose ages have been confirmed through official records. While DNA testing can provide strong evidence of a person’s age, it is not always a reliable method on its own.
Longest confirmed lifespan
The longest verified human lifespan on record is that of Jeanne Calment, a French woman who lived to be 122 years and 164 days old. She was born in 1875 and lived through both World War I and II, witnessing significant social and technological changes throughout her life. Calment’s age has been confirmed by multiple sources, including her birth and baptismal records, as well as historical documents from throughout her life.
Current contenders
As of 2021, there are several people who are believed to be among the oldest living humans. These individuals include Kane Tanaka, a Japanese woman who was born in 1903 and is currently 118 years old, and Lucile Randon, a French nun who was born in 1904 and is also 118 years old. While their ages have not been officially confirmed, they are both considered credible contenders for the title of oldest living human.
The role of genetics
While genetics may play a role in determining lifespan, it is not the only factor. Many researchers believe that factors such as lifestyle, environment, and access to healthcare also contribute to how long a person can live. Additionally, while some genetic mutations have been linked to increased longevity, these mutations are rare and do not necessarily guarantee a longer lifespan.
Lifestyle factors
Lifestyle choices can have a significant impact on a person’s lifespan. Factors such as diet, exercise, and stress management can all contribute to a longer, healthier life. Studies have shown that people who follow a healthy lifestyle are more likely to live longer than those who do not. Additionally, factors such as smoking and excessive alcohol consumption have been linked to a shorter lifespan.
Centenarians vs supercentenarians
Centenarians are people who live to be 100 years old or older, while supercentenarians are those who live to be 110 years old or older. While both groups are considered to have exceptional longevity, supercentenarians are a much rarer group. It is estimated that there are only about 50 to 100 supercentenarians alive at any given time, compared to millions of centenarians.
The impact of geography
Certain regions around the world are known for having a higher concentration of long-lived people. These regions, known as "blue zones," include areas such as Okinawa, Japan; Sardinia, Italy; and Nicoya, Costa Rica. Researchers have studied these areas in an effort to understand the lifestyle and environmental factors that contribute to longevity.
Longevity research
Scientists around the world are actively researching ways to extend the human lifespan. This research includes studying the genetics of long-lived people, developing anti-aging drugs, and exploring the potential of technologies such as stem cell therapy. While significant advances have been made in this field, there is still much to learn about the complex factors that contribute to human longevity.
Conclusion
Determining who the oldest living human being is can be a difficult task, but several people around the world are believed to be among the oldest living humans. While genetics may play a role in determining lifespan, factors such as lifestyle, environment, and access to healthcare also contribute to how long a person can live. Ongoing research into extending the human lifespan shows promise but also highlights the complexity of this field. Ultimately, the title of oldest living human is a constantly shifting one, as new contenders emerge and others pass away.
