Each year, American adults have, overall, a 1-in-1,743 chance of dying in an accident. That means that even if nothing else killed you—doing away with old age and disease—you would on average live to be 1,743 years old before a fatal accident. But you could do better. A 9-year-old child has much lower odds of accidental death, about 1 in 10,000. If we could keep everyone to this low rate (avoiding work and driving would probably help), we could typically live 10,000 years. About 37 percent of the population would do better yet, living on average to the ripe old age of 20,000, says James Vaupel, director of the Max Planck Institute for Demographic Research.
