This century's march of increasing life expectancy has almost reached an end, at least in the developed countries. Better nutrition, medical care, public health facilities, and accident prevention have helped boost life expectancy at birth from 47.9 years in 1900 to 69.2 years in the mid-1950s and then, more slowly, to 74.9 years in 1989.

The accelerating nature of the aging process has been revealed by improvements in our living conditions, which have decreased young people's chances of death more than they have decreased their elders'.
