Erfahrung und Technik in der Produktionthough such debates commonly dwell on the issue of which approach is “superior,” it is far more fruitful to acknowledge that both approaches offer unique perspectives on aging, and hence these approaches are complementary rather than antagonistic. There are three basic levels of control of aging: 1)

More recently, changes in brain size following enrichment have been shown in rats over 900 days of age

In reliability theory, failure phenomena are usually classified according to the monotone properties of the hazard rate h(x) = g(x)/R(x), where h is th

However, when set against the fact that the bodies of higher animals are intrinsically mortal, yet composed of the same basic materials as their germ cells, the observation leads to the central puzzle of gerontology.

However, in the hierarchy of biological systems gerontologists have largely restricted their interests to the levels from the biomolecule to the population and have integrated those areas of biology which address those levels. Other areas of study that could also contribute to gerontology have

According to an analysis by Economos (1980b), the correlation coefficient of log BW vs. log LS within the mammalian class as a whole is high (? = 0.79). This relation appears to hold within all mammalian orders. Within the order Rodenti
