title: Aging hypotheses, aging markers and the concept of biological age.
abstract: The following two points are made in this article: (1) the likely existence of more than one underlying cause of senescence strengthens the case for the development of a number of reliable markers of aging and (2) the concept of a single biological or functional age for an organism should be used with great caution, if at all.
