Aging Happens by Default

Alvaro Macieira-Coelho*

With rare exceptions theories proposed to explain aging focalized in general on one specific aspect of the functioning of the organism. This does not seem reasonable, as the cause of such a general phenomenon cannot be pinpointed. One has to look for the phenomenon of aging in terms of the broad requirements needed for life to persist; the most fundamental requirement is energy expenditure, which inevitably follows the second law of thermodynamic. Hence aging is an unavoidable event, there is no alternative it is inherent to the process of existing.
