长寿科学被过分炒作,但这项研究可能改变人类
尽管长寿研究领域充斥着过度炒作和夸大宣传,但Altos Labs等机构正在进行的细胞重编程与再生医学研究,有望从根本上延缓甚至逆转衰老过程。这项探索不仅可能延长人类寿命,更可能改变我们对疾病、衰老乃至生命本身的认知方式。

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.
