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.

He and Sergei Scherbov of the Vienna lnstitute 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.

New foods and the New World

A recent poll for the charity Ramblers a quarter of adults walk for no more than an hour a week,but being active is known to reduce the risk of a number of cancers. This study, published in Cancer Epidemiology, Biomarkers&Prevention, followed 73.615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group.
