Summary
A study by the Max Planck Institute for Evolutionary Anthropology found that women generally live longer than men, a trend observed across many species. Factors such as genetics, risky behaviors, and biological differences explain this gap, which averages 5.8 years in the U.S. as of 2021. Researchers suggest men might narrow this gap through lifestyle changes, like visiting doctors more often and improving diet and exercise habits.
Key Facts
- In 2021, the life expectancy gap between men and women in the U.S. was 5.8 years.
- Women typically live about 81 years, while men live nearly 76 years on average.
- The study analyzed 528 mammal species and found females often live longer than males.
- Genetics, mating behaviors, and caretaking roles are factors contributing to this longevity gap.
- Female mammals, including humans, usually have two X chromosomes, which might offer genetic protection.
- Male behaviors like smoking and drinking contribute to shorter lifespans.
- Men are more likely to die from causes such as alcoholism, drug use, and certain types of cancer.
