Many studies point to factors capable of increasing longevity but many questions regarding this subject were still not elucidated. The perceptions of the old aged themselves with respect to factors that contribute to longevity are important, allowing to identify each factor and its interactions with other variables promoting longevity. ⋯ The analysis of their discourse led to the conclusion that the perception of the factors can be grouped around progressively inclusive categories that culminate in the collective representation that longevity depends on the balance between negative life-destroying factors and healthy, life-generating and life-preserving factors. The lack of social and state control over these factors is generating a pessimistic view for the future.

[The relevance of qualitative techniques in biomedical research].
On observing how qualitative and quantitative studies are reported in the biomedical literature it becomes evident that, besides the virtual absence of the former, they are presented in different ways. Authors of qualitative studies seem to need almost invariably to explain why they choose a qualitative approach whereas that does not occur in quantitative studies. This paper takes Ludwik Fleck's comparative epistemology as a means of exploring those differences empirically, illustrating on the basis of two studies dealing with different aspects of biomedical practices how qualitative methods can elucidate a variety of questions pertaining to this field. The paper concludes presenting some structural characteristics of the biomedical field which on one hand, would not be explored properly without employing qualitative methods and, on the other hand, can help understanding the little value given to qualitative techniques in this area.
