Recent studies have provided intriguing insights into the longevity gap between women and men. Various research efforts indicate that female mammals generally outlive their male counterparts due to a combination of factors, including evolutionary advantages, sexual behaviors, and genetic influences. Notably, a study of 1,176 species points to the role of polygamy and the hectic sex lives of males contributing to their shorter lifespans. Scientists are now suggesting that understanding these dynamics may help in closing the longevity gap, emphasizing that the differences in lifespan are not solely biological but also influenced by behavior and environment. This growing body of research aims to shed light on the evolution of lifespan differences across cultures, ultimately helping to inform future longevity treatments.
