Whose lifespan is more? The factors influencing longevity

According to the World Health Organization (WHO), global life expectancy has increased significantly over the past century, reaching an average of 73.1 years in 2019 before the COVID-19 pandemic caused a temporary setback. When considering whose lifespan is more, research consistently shows that women tend to outlive men in nearly every country worldwide. The reasons behind this persistent longevity gap involve a complex interplay of genetic, biological, and social factors.
