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 (人口统计学)at the Austrian (奥地利的) 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, according to research reported in the journal Nature on Wednesday. However, by 2050 the average German will be 51.9 years old and will be expected to live another 37.1 years. So middle age in 2050 would occur at around 52 years instead of 40 years as in 2000.
"As people have more and more years to live they have to save more and plan more and they effectively are behaving as if they were younger," said nderson.
Five years ago, the average American was 35.3 years old and could plan for 43.5 more years of life. By 2050, the researchers estimate it will increase to 41.7 years and 45.8 future years.
"A lot o; our skills, our education, our savings and the way we deal with our health care depend a great deal on how many years we have to live," said Sanderson.
This dimension of how many years people have to live has been completely ignored in the discussion of aging so far.

The Employee Retirement Income Security Act of 1974 provided for the first IRAs. It set roles for retirement plans run by big businesses. Other measures provided for individuals who did not qualify for such plans, called pensions. The first kind of IRA is now called a traditional IRA. A worker can put up to 4,000 dollars of his or her yearly earnings into a special account. Workers over the age of fifty can invest 4,500 dollars. Unlike a pension, the saver controls the account and decides how it is invested. Money put in a traditional IRA is not taxed until it is withdrawn. But, savings cannot be withdrawn before the account holder is 59. 5 years old. If the money is withdrawn before that time, it is taxed like income and there is a 10 percent fine.
At first, IRAs were only for people not covered by pensions at work. But in 1981, everyone could open an IRA. Six years later, Congress banned highly-paid individuals from claiming tax reductions.
When were the first IRAs put into practice？
(30)
A．In 1930s.
B．In 1970s.
C．In 1940s.
D．In 1980s.
