Women who gave birth to twins outperform their peers who only ever had one child at a time

On average, they live longer after menopause. They give birth more frequently, and over the course of their lives, they raise more children. They have children later on into their lives, and over a longer part of it. These advantages held even after adjustments were made to account for things like the women’s age, when they gave birth to their first child, whether their husbands or children died, and their religious affiliations. This contradicts the idea that twins harm the health of the mother. Instead, it is quite the opposite. The twin-bearers live longer and raise more children. They even tend to have more singletons than other mums, which means that even excluding their twins, they would still end up with larger families. In addition, mothers of twins tend to be taller than singletons.
