Could We Reach Immortality? WA
The idea of living forever might seem like one that's limited to fairy tales, particularly if you were born in the 1800s when the average life expectancy was only 35 years [source: Sieberg]. However, men in the U.S. today have a life expectancy of 75 years and women 80 years [source: O'Neill]. If life expectancy can more than double in 200 years, then might it double again? Could it continue to do so infinitely?
