If aging could only be postponed! Do you long for such a breakthrough? Who would not like to escape wrinkles, gray hair, brittle bones, loss of stamina, forgetfulness, vulnerability to sickness, and finally death? from what science has already achieved, is there any real basis for such optimism?
During this century, the developed countries of the world have experienced a dramatic increase in life expectancy. For example, in the year 1900 the average life expectancy of men in the United States was 46 years. “From 1900 to 1980 male life expectancy at birth increased 51% to 69.9 years,” states the American Journal of Gerontology. Now it is 71.8 years for men and 78.8 years for women. A number of other countries have an even higher life expectancy, with Japan the highest—74.2 years for men and 79.8 years for women. Does this prove that man’s life span has been extended?
The dramatic increases noted above are due largely to a lower infant-mortality rate. Today, more babies survive to adulthood than in past centuries. “Medical advances,” explains The Body Book, “have increased average life expectancy, but they have not increased the maximum life span.” As Brian Stableford, a biologist at the University of Reading, England, expressed it in his book Future Man: “Our lifespan has been reckoned since Biblical times as 70 years, and although two thousand years of scientific advancement have allowed many more people to reach that term, scientists have so far done nothing to extend it.” (Psalms 90:10)
