We are raising fewer children, losing far fewer of them, and living much longer lives, collectively painting a picture of a humanity that is finally—though still unevenly—winning the ancient battle against early death, only to now face the complex modern puzzles of aging populations, persistent inequalities, and our own mental well-being.
