人类衰老的进程,可用测定的指标来判断。通常所指的“年龄”,习惯用出生年月日来计算,此称“日历龄”。但这只不过是个体所经历的时间,不能完全说明个体衰老程度。一般来说“生物学年龄“随”日历龄”的增加而增加。但个体“生物学年龄”增加的幅度不完全相同,“生物学年龄”相同的个体,“日历龄”不一定相同,衰老可推迟,也可提前,存在着个体差异,并与遗传及环境诸因素有关。衰老与疾病的区别,后者在于某种疾病引起的器官功能衰退常局限于某一器官,而衰老则是全身器官的功能的逐渐减退。 The process of human aging can be judged by the measured indicators. Usually referred to as “age” is used to calculate the date of birth, this is called “calendar age”. But this is only the time that the individual experiences. It cannot fully explain the age of the individual. In general, “biological age” increases with the “calendar age”. However, the individual’s “biological age” is not exactly the same. The individuals with the same “biological age” may not necessarily have the same “calendar age”. The aging may be postponed, or it may be earlier, there are individual differences, and it is related to heredity and environment. Factors related. The difference between aging and disease, the latter is that the decline of organ function caused by a disease is often limited to an organ, and aging is the gradual decline of the function of the body organs.
