OBSOLETE. A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death and may succeed developmental maturation (GO:0021700).

Comment
The reason for obsoletion is that it is not a normal, genetically encoded biolgical program, but a phenotype resulting from cellular malfunctions that accumulate over time, including oxidative damage, etc.
