Do mothers with sons live longer? The surprising link between child's sex and maternal longevity

In a pre-industrial Finnish study, researchers found that a mother's risk of death increased by 7% per year for each son born. The popular notion that mothers with sons live longer is challenged by scientific findings, which often suggest a correlation between bearing sons and a slightly shorter maternal lifespan. This complex connection involves a mix of biological and social factors that can impact a mother's health and longevity.
