长寿科学被过度炒作,但这项研究可能改变人类
尽管长寿科学领域充斥着过度炒作和夸大承诺,但Altos Labs等机构正在进行的前沿细胞重编程研究,可能真正开启人类寿命延长的革命。这项研究聚焦于逆转细胞衰老、恢复组织活力,其潜在影响远超当前流行的抗衰老补剂和疗法,有望从根本上改变人类对年龄和寿命的认知。

The prevalence of dementia at given ages has decreased compared to decades ago. Today's 90-year-olds have less than half the dementia risk compared to those in 1984.
Research indicates that the heritability of human lifespan is approximately 50% when using a redefined concept of heritability. This suggests genetic factors account for about half of lifespan variation, while environmental and other factors contribute the remaining half.
Heritability measures how much of the variation in a trait within a population is due to genetic differences. It does not indicate how much of an individual's trait is determined by genes versus environment. The concept is often misunderstood in discussions about intelligence, personality, and other complex traits.
