从豪宅到专机,享受诸多特权的美国总统们,也有着比常人更多的压力和烦恼。按常理,他们应该衰老的更快。但是美国一项研究表明,总统们老得快但寿命长。美国伊利诺伊大学研究者奥利尚斯基主攻人类衰老学科,他有一套寿命预期模型。这一模型计入各种因素,包括生存环境、饮食、压力、医疗状况等,可预期或计算某一时期特定年龄人群的寿命,也可针对某一特定个体定制,单独预期寿命。奥利尚斯基以美国历史上的所有总统为研究对象。结果发现,自然死亡的34位美国总统平均年龄73岁,比模型预期的68岁长5年。其中,实际死亡年龄超过68岁的总统总计11人,平均寿命78岁。奥利尚斯基说,历任总统时常面对高强度压力,衰老速度肯定比同龄人要快。但他们受教育水平、特别是他们担任总统后所获得的医疗服务一般都高于同龄人平均水平,因此,总统衰老快但是寿命更长。
The American presidency comes with perks, from a very nice house to a handy jet at your disposal, but the job also comes with plenty of stress.
Enough stress to take years off your life? Maybe not, new research suggests.
The data showed that presidents who die of natural causes don't seem to lose years off their lives due to the effects of time spent in the White House. In fact, most of them managed to live longer than similar men of their era.
