Ageing is a complex, multifactorial phenomenon. The existence of biologic rhythms as well as the study of their modifications or their alteration in the aged are useful and pertinent to understand the biologic age. These modifications, if any, may be interpreted as a change in the adaptability of aged subjects to environmental factors. The loss or decrease of adaptation capacity with ageing is worth quantifying. This paper rounds up the question.
衰老 是一种复杂的、多因素的现象。生物节律的存在以及对其在老年人中的变化或改变的研究，对于理解生物年龄是有用且相关的。这些变化（如果有的话）可以被解释为老年个体对环境因素适应能力的改变。随着衰老而丧失或降低的适应能力值得量化。本文围绕这个问题展开论述。
