“Aging (Biological Aging)”  

Aging

  To our body, Aging (Biological Aging), a physiological process, is the progressive accumulation of changes in structure and function that our body makes as a result of the passage of time.
  To our body, Aging is a process of changes that are deleterious, progressive, universal and to the mostly irreversible, and may increase the probability of dis-eases and death. *

  Disorders of Aging (Aging Disorders)

Aging Process is Distinct from the Diseases of Aging

  Aging damage occurs to molecules (DNA, proteins, lipids), to cells and to organs. Diseases of old age (diseases which increase in frequency with age, such as arthritis, osteoporosis, heart disease, cancer, Alzheimer's Disease, etc.) are often distinguished from aging.   The aging process is distinct from the diseases of aging, but the damage associated with the aging process is real and increases the probability that diseases of old age will occur. **

“Senescence vs Aging Process”  

  Allopathic gerontologists prefer to use the word senescence because "aging" implies that the passage of time necessarily results in deterioration (biological entropy), which is not true during the early, developmental, time of life (before the age of 10 or 12 in humans).

Senescence

  The "Aging Process" not "Senescence" is the universal association between aging & deterioration in the progression of our adult years. The distinction between our body's aging and our body's development progress is obvious.

Senescence is a complex process in an organism's genetic make up so that it may live to its healthiest until its reproductive age and die slowly and gradually thereafter.
  Senescence encompasses all of the biological processes of a living organism's approaching an advanced age (i.e., the combination of processes of deterioration which follow the period of development of an organism). Cellular senescence is the phenomenon by which normal diploid cells lose the ability to divide. Organismal senescence is the aging of whole organisms **
