衰老研究中的一个基本问题是，人类和其他物种是否拥有一成不变的寿命限制。我们调查了瑞典的最高死亡年龄，从19世纪60年代的约101岁上升到90年代的约108岁。在1969年之前，增长速度为每十年0.44年，但在那之后，增长速度加快到每十年1.11年。从1861年到1999年，最高死亡年龄上升的70%以上可归因于70岁以上死亡率的下降。其余的原因是老年幸存者的数量增加(包括更大的出生队列和从婴儿期到70岁的存活率增加)。自1969年以来，最高年龄的上升速度更快，是因为近几十年来老年死亡率下降的速度更快。
A fundamental question in aging research is whether humans and other species possess an immutable life-span limit. We examined the maximum age at death in Sweden, which rose from about 101 years during the 1860s to about 108 years during the 1990s. The pace of increase was 0.44 years per decade before 1969 but accelerated to 1.11 years per decade after that date. More than 70 percent of the rise in the maximum age at death from 1861 to 1999 is attributable to reductions in death rates above age 70. The rest are due to increased numbers of survivors to old age (both larger birth cohorts and increased survivorship from infancy to age 70). The more rapid rise in the maximum age since 1969 is due to the faster pace of old-age mortality decline during recent decades.
