    When Death Was Young

    In 1800, a newborn child could expect to live just thirty-five years. Today, that number has doubled. We've each been gifted roughly twenty thousand extra days-an entire second life that our ancestors never knew. Yet we barely notice this miracle. We complain about aging, fear death at seventy, and take for granted that most children will survive to adulthood. But this wasn't inevitable. For ten thousand years, human life expectancy remained trapped beneath an invisible ceiling. One-third of children died before reaching adulthood whether they lived in ancient Rome or medieval London, in agricultural villages or hunter-gatherer bands. What shattered this ancient pattern? The answer isn't what you'd expect. It wasn't brilliant doctors or lone scientific geniuses. Instead, it was an unlikely network of activists, bureaucrats, journalists, and ordinary people who refused to accept that early death was humanity's fate.
