tb天博体育：科学家称人类寿命最高“上限”为115岁

Researchers claim to have discovered the maximum age ceiling for human lifespan.研究人员称之为，他们找到了人类寿命的下限。Despite growing life expectancy because of better nutrition, living conditions and medical care, Dutch scientists say our longevity cannot keep extending forever.荷兰科学家回应，虽然营养条件、生活环境和医疗水平的变革提升了人类的预期寿命，但是人类的寿命会无限缩短。Women can only live to a maximum of 115.7 years, they said, while men can only hope for 114.1 years at the most.科学家称之为，女性最多能活到115.7岁，而男性则为114.1岁。

The research by statisticians at Tilburg and Rotterdams Erasmus universities said however there were still some people who had bent the norm, like French woman Jeanne Calment who died at the ripe old age of 122 years and 164 days in 1997.但是，蒂尔堡大学和鹿特丹伊拉斯姆斯大学两校统计学家的研究回应，还是有一些人突破了这一极值。比如，来自法国的雅娜?卡尔芒就活着了122岁零164天，于1997年去世。Lifespan is the term used to describe how long an individual lives, while life expectancy is the average duration of life that individuals in an age group can expect to have - a measure of societal wellbeing.寿命回应的是每个人的生命期限，而预期寿命是指同年龄段中的平均值预计寿命，预期寿命是社会福利的一种衡量标准。The team mined data over 30 years from some 75,000 Dutch people whose exact ages were recorded at the time of death.该统计资料小组倒数30年对荷兰大约75000名居民展开了数据采集，记录了拒绝接受调查者去世时的清楚年龄。

On average, people live longer, but the very oldest among us have not gotten older over the last thirty years, Professor John Einmahl said.约翰?艾马尔教授称之为：“人们的平均寿命缩短了，但是最低年龄在过去30年内并没减少。”There is certainly some kind of a wall here. Of course the average life expectancy has increased, he said, pointing out the number of people turning 95 in The Netherlands had almost tripled.“人的生命是有休止符的。

当然人类平均寿命变大了。”他认为，荷兰95岁以上的人数完全减少了两倍。Nevertheless, the maximum ceiling itself hasnt changed, he said.“然而，最低年龄仍然没变化。

”The Dutch findings, to be published next month, come in the wake of those by US-based researchers who last year claimed a similar age ceiling.这项调查结果将于下月公开发表，美国研究人员去年曾公布了类似于的人类年龄下限研究结果。However, that study by Albert Einstein College of Medicine in New York found that exceptionally long-lived individuals were not getting as old as before.但是，纽约阿尔伯特?爱因斯坦医学院的研究也找到，如今十分长寿的人寿命也没过去那么宽。Einmahl and his researchers disputed that, saying their conclusions deduced by using a statistical brand called Extreme Value Theory, showed almost no fluctuation in maximum lifespan.艾马尔及其研究人员回应回应异议，他们说道那项美国的研究结果是由统计学的“极值理论”推论出来的，其结果中，人类的最低寿命完全没波动。They claim it provides the most accurate assessment.美国研究人员说道这是最准确的评估方法。

However, scores of other research teams have challenged the idea of a limit so close to 100.然而其他研究小组的研究结果与年龄无限大在100岁附近的结果有所不同。Earlier this year, another team of Dutch researchers, this time from the University of Groningen, said 125 is achievable by 2070.今年早些时候，另一组来自荷兰格罗宁根大学的研究人员称之为，2070年人类的最低寿命平均125岁。Meanwhile, a team from McGill University challenge whether there can be any limit on how long people can live.同时，麦吉尔大学的研究小组也在探究人的寿命否有下限。
