活得长,不等于活得健康。简单来说,衰老的定义是生物体的生物学功能随时间发生一系列变化的过程。这些变化通常包括免疫、肌肉、认知和代谢功能的下降,最终导致生物体的死亡。对人类来说,衰老的过程也伴随疾病的侵扰,其中阿尔茨海默氏症、癌症和心脏疾病的得病风险较高。这些生理老化的指标难以测量,而目前典型的衰老研究则主要通过死亡率或寿命来评估治疗、养生的有效性,以及研究衰老过程中发生的基因突变。然而,这些指标无法充分诠释衰老过程,并不能为个体或群体健康 Live long, not equal to live healthy. In a nutshell, the definition of aging is the process by which a series of changes in the biological function of an organism take place over time. These changes often include a decline in immune, muscle, cognitive, and metabolic functions that ultimately lead to the death of the organism. For humans, the process of aging is also accompanied by disease, of which Alzheimer’s disease, cancer and heart disease are at higher risk. These indicators of physiological aging are difficult to measure. However, the typical aging study now mainly evaluates the effectiveness of treatment and regimen through mortality or life expectancy and studies genetic mutations that occur during aging. However, these indicators do not adequately interpret the aging process and do not provide for individual or group health
