Any modern theory of longevity has to take into account the multifactorial combined effect of biological-medical, social and psychological factors and of factors pertaining to molecular biology, each with their different weighting. For this reason research into greater-than-average life expectancy and longevity is only possible on an interdisciplinary basis. Many theories of longevity despite convincing arguments also have their weak points. Critical analysis of the theories available to date reveals that longevity rests on an optimal combination of two major factors: 1. on a genetic predisposition in people with longevity in the family--this is the case in most instances. 2. on additional exogenous factors of a social, psychological, ecological and medical kind.
任何现代长寿理论都必须考虑生物医学、社会和心理因素以及分子生物学相关因素的多因素综合作用，每个因素的权重各不相同。因此，只有在跨学科的基础上，才有可能对高于平均预期寿命和长寿进行研究。许多长寿理论尽管有令人信服的论据，但也有其弱点。对现有理论的批判性分析表明，长寿取决于两个主要因素的最佳组合：1. 家族中有长寿者的人所具有的遗传倾向——在大多数情况下都是如此。2. 社会、心理、生态和医学等方面的额外外部因素。
