Global life expectancy has increased significantly over the past century, a testament to humanity's progress. Understanding what are the reasons for high life expectancy rates provides critical insight into creating a healthier future for all, especially as we age.
According to the American Psychological Association, older Americans in the lowest wealth decile lack the pensions and assets enjoyed by their more affluent peers, leading to greater economic vulnerability. This stark reality brings to light the critical question: **How does socioeconomic status affect aging?** The influence is complex and far-reaching, spanning financial stability, access to healthcare, and a host of lifelong environmental factors.
According to data from the Centers for Disease Control and Prevention (CDC), Asian people have the longest average life expectancy in the United States. However, the question, "What race is known to live the longest?" is more complex, as average life expectancy data can obscure significant variations within and across racial and ethnic groups.
While genetics account for only 20-30% of one's expected lifespan, lifestyle and socioeconomic factors are often more influential in determining how long a person lives. Understanding **what is the biggest predictor of life expectancy?** requires examining a combination of interconnected elements, rather than identifying a single cause.
Studies suggest that genetics may only account for about 25% of human longevity, indicating that the majority of our lifespan is shaped by other, more controllable factors. Understanding what influences life expectancy the most requires examining the complex interplay between our genes and our environment.
According to the Centers for Disease Control and Prevention (CDC), average life expectancy can vary significantly across different demographic groups based on factors like race, ethnicity, gender, and socioeconomic status. Understanding which group has the longest life expectancy provides valuable insight into the complex interplay of health, environment, and social determinants that shape human longevity.
Recent studies, including a major analysis published in *Nature Medicine*, have shown that environmental factors like smoking and physical activity have a greater impact on lifespan and premature death than genetic predisposition. This research fundamentally redefines the answer to the question: What is the strongest predictor of all-cause mortality? It moves the focus from unchangeable DNA to factors within our control or sphere of influence.
