Eli5: Why do women live longer than men on average, even among the older population like supercentenarians?
In: 2368
One major factor is likely metabolic rate. Across species, those with lower metabolisms live longer. Women have a lower nominal metabolic rate than men.
Other factors, such as engaging in dangerous or physically strenuous activities also play a role. However, metabolic rate is generally the base factor for lifespan among living things.
