Final answer:
People with higher education levels usually live longer because education is an investment in economic growth with benefits beyond the current generation. For example, girls in low-income countries who receive more education tend to have healthier children who are better-nourished and receive basic health care.

Research has shown that people with higher education levels usually live longer. Education is an investment in economic growth that has benefits beyond the current generation. For example, girls in low-income countries who receive more education tend to have fewer, healthier, and better-educated children. Their children are more likely to be well-nourished and receive basic health care, leading to improved overall health outcomes.
