The theory of aging that supports your belief that strict infection control prevention measures are necessary is the Immunological Theory of Aging. The Immunological Theory of Aging states that aging leads to the decline of the person’s defensive immune system and the decreased ability of the antibodies to protect us against infection.

The Programmed Longevity Theory of aging states that genetic instability and changes occur such as some genes turning on and off lead to the aging process; the Endocrine Theory of aging states that aging results from hormonal changes and the biological clock’s ticking; and Rate of Living Theory states that one’s longevity is the result of one’s rate of oxygen basal metabolism.

Other theories of aging are:

Wear and Tear Theory: This theory describes aging as a function of the simple wearing out of the tissues and cells as one ages.
Cross Linking Theory: This theory of aging explains that aging results for cell damage and disease from cross linked proteins in the body.
Free Radicals Theory: This theory is based on the belief that free radicals in the body lead to cellular damage and the eventual cessation of organ functioning.
Somatic DNA Damage Theory: Somatic DNA Damage theory is based on the belief that aging and death eventually occur because DNA damage, as continuously occurs in the human cells, continues to the point where they can no longer be repaired and replaced and, as a result, they accumulate in the body.
