Move over Methuselah. Future generations could be living well into their second century andstill doing Sudoku, if life expectancy predictions are true. Increasing by two years every decade,they show no signs of flattening out. Average lifespan worldwide is already double what it was 200years ago. Since the 1980s, experts thought the increase in life expectancy would slow down andthen stop, but forecasters have repeatedly been proved wrong.
The reason behind the steady rise in life expectancy is "the decline in the death rate of theelderly", says Professor Tom Kirkwood from Newcastle University. He maintains that our bodies areevolving to maintain and repair themselves better and our genes are investing in this process to putoff the damage which will eventually lead to death. As a result, there is no ceiling imposed by thereahties of the ageing process."There is no use-by-date when we age. Ageing is not a fixed biological process," Tom says.
A large study of people aged 85 and over carried out by Professor Kirkwood discovered that there were a remarkable number of people enjoying good health and independence in their late 80s and beyond. With people reaching old age in better shape, it is safe to assume that this is all due to better eating habits, living conditions, education and medicine.
There are still many people who suffer from major health problems, but modem medicine means doctors are better at managing long-term health conditions like diabetes, high blood pressure and heart disease."We are reaching old age with less accumulative damage than previous generations. We are less damaged," says Professor Kirkwood. Our softer lives and the improvements in nutrition and healthcare have had a direct impact on longevity.
Nearly one-in-five people currently in the UK will live to see their lOOth birthday, the Office for National Statistics predicted last year. Life expectancy at birth has continued to increase in the UK--fro
从字义来看，mortality是“死亡，致命”的意思，因此画线词就是较低死亡率的意思；另外从语境来看，这是由and连接的两个并列成分，good life expectancy and low mortality，并列的成分前后含义应该接近，前面说的是较长的寿命，刚好和后面的较低死亡率同义转换。因此正确答案为B。
