Sažetak

Aging interventions will be ineffective if we do not understand the basic principles
of aging. Currently, there is no consensus on the issue whether aging is programmed or not. The hypothesis
presented in this article indicates that aging (at least graying of male hairs) is programmed.
This hypothesis is supported by the symmetry of the graying of male beard hairs. According to stochastic
theories of aging, aging is a passive non-programmed process where random dispersion of
graying hairs should result. On the contrary, programmed theories of aging would predict that there
should be symmetry on the left and right parts of the face showing the same proportion, pattern and
time of appearance of graying hairs.
