Forty May Be the New 30 as Scientists Redefine Age
Is 40 really the new 30 In many ways people today act younger than their parents did at the same age.
Scientists have defined a new age concept and believe it could explain why populations are aging, but at the same time seem to be getting younger.
Instead of measuring aging by how long people have lived, the scientists have factored in how many more years people can probably still look forward to.
Using that measure, the average person can get younger in the sense that he or she can have even more years to live as time goes on, said Warren Sanderson of the University of New York in Stony Brook.
He and Sergei Scherbov of the Vienna Institute of Demography at the Austrian Academy of Sciences, have used their method to estimate how the proportion of elderly people in Germany, Japan and the United States will change in the future.
The average German was 39.9 years old in 2000 and could plan to live for another 39.2 years, accor
A. at 37.1 years.
B. at 40 years.
C. at 39.2 years.
D. at 52 years.
