title: [Asynchronous aging and biological aging].
abstract: The author deals with problems arising from the attempt to determine the biological age of man, as a result of asynchronous ageing. Selected findings, including the author's are presented to prove that differentiation and a critical approach are required in collecting and interpreting what is known as ageing data which serve to find the biological age by way of cross-sectional studies.
