According to a 2018 study in *The Lancet*, being underweight can shorten a person's life expectancy by several years compared to a healthy weight. Understanding how long do underweight people live involves examining underlying health conditions, nutritional deficiencies, and other contributing factors that can impact overall longevity.

The world’s oldest person on record, Jeanne Calment, lived to be 122 years and 164 days old. This remarkable longevity has prompted intense scientific debate about the true limits of human existence and begs the question: **What is the longest a human can survive?**

According to the CDC, life expectancy is the average number of years of life remaining to a person at a particular age, based on a given set of age-specific death rates. Knowing **how do they determine life expectancy?** involves understanding the statistical and demographic methods used to project these averages.

As of 2022, the worldwide average life expectancy was 72 years, a figure that has dramatically increased since the early 20th century. The question, 'Is 72 a good life expectancy?' is relative, as personal health, genetics, and environment play a significant role in one's individual outcome.

Recent studies using large datasets have shown that lifestyle and environmental factors account for a significantly higher percentage of mortality risk than genetics. This groundbreaking research offers a new perspective on what is the main factor of determining mortality, pointing toward modifiable aspects of our lives and societal structures.

Research consistently shows that while many elements contribute to a long life, lifestyle choices are the most significant modifiable factors an individual can control to enhance their health and longevity.

While access to medical care is often cited, health experts agree that social and environmental factors, alongside personal lifestyle choices, account for a far greater percentage of your overall health and longevity. So, what is the most important factor in your health? The answer is more complex and empowering than you might think.
