Due to a deteriorative disease, his lower face is damaged with red/blue eye and a bald head.

It is generally accepted that deteriorative processes (wear, other molecular damage) exist and that living organisms have mechanisms to counter deterioration.

A. There are items in the Department of Defense (DoD) and the Federal Supply System that require special handling due to certain deteriorative characteristics.

Immunosenescence is not a random deteriorative phenomenon, rather it appears to inversely repeat an evolutionary pattern and most of the parameters affected by immunosenescence appear to be under genetic control.

Longer lived species possess many mechanisms for offsetting damage due to causes such as oxidation, telomere shortening, and other deteriorative processes that are each more effective than those of shorter lived species.

Afterwards, geneticists had wryly demonstrated that-since each racial group was so small that unless their descendants intermarried, each would undergo deteriorative genetic drift due to inbreeding on the colony planet-the racists had made cross-breeding necessary to survival.
