More than a third of the babies born this year could receive a 100th birthday message from whoever happens to be on the throne in the second decade of the 22nd century, according to figures published by the Office for National Statistics (ONS). It forecasts that 35% of the 826,000 people born in 2012 will live to become centenarians.
But a long life is not unalloyed good news. David Sinclair, head of policy and research at the International Longevity Centre UK, warned that for many the future may mean social isolation(隔离）as they live longer than friends and members of their families.
"It is of course good news that so many more people are living longer," he said, "but there is a big 'but¹. We will be older, but in worse health, and at high risk of living alone. The other problem is that we are very poor at forward planning. We deal with the problems that are under our noses, but even problems two or three years away seem quite distant enough to put off.When you're talking about forecasts for a time half a century away and more, I see no evidence that we are putting in place the measures to deal with it."
This year there will be 14,500 centenarians in the UK, a number which is expected to increase to 110,000 in 2035.
Women have higher life expectancies than men at every age: the likelihood of a girl born this year reaching her century is estimated to be 39%; for boys the figure is 32%.
The estimated number of female centenarians has risen from 500 in 1961 to more than 10,000 in 2010，a figure which is projected to reach 71,000 by 2035 and 276,000 by 2060.
Men are also living far longer, although their numbers are far fewer. There were an estimated 92 male centenarians in 1961 and just below 2,000 in 2010.
