Narwhals maximum life span is about 50 years (寿命:独角鲸的最大寿命大约为50年。 )
Evidence synthesis : it is not known whether calorie restriction extends maximum life span or life expectancy in lean humans 证据分析:还不知道限制热量的摄入能最大的延长瘦人的生命或预期寿命。
In rodent models , calorie restriction with adequate nutrient intake decreases the risk of developing chronic disease and extends maximum life span 在动物模型中,摄取足够的营养并且限制热量的摄入能够减少慢性疾病发生的危险,并能延长寿命。
They and the other monkeys must be followed still longer , however , before we will know whether low food intake can increase both average and maximum life spans in monkeys : rhesus monkeys typically live about 24 years and sometimes up to 40 ; squirrel monkeys typically live about 19 years but may live for 28 但想要知道限食是否会延长猴子的平均寿命及最长寿命(恒河猴一般活到24岁,有时可到40岁;松鼠猴一般活到19岁,但有时可到28岁) ,我们还必须对这些恒河猴及其他猴子做更久的追踪研究才行。
Maximum life span refers to a measure of the maximum amount of time one or more members of a population has been observed to survive between birth and death. The term can also denote an estimate of the maximum amount of time that a member of a given species could survive between life and death, provided circumstances that are optimal to their longevity.
