Application of Aging Theories


Aging is a steady decline in health, which is instrumental in shortening lifespan; and the aging process is the duration during which such changes occur. Aging occurs throughout most of lifespan. Such a process is an accumulation of changes, which may be subtle or even drastic, that progressively lead to disease, degeneration, and, ultimately, death.

Many scientists have come up with different theories explaining why and how you age. Putting into practice the theories of aging may defer and delay your own aging process.

The free radical theory of aging

This theory is based on the damage of cells due to cumulative free radicals, leading to disease and, ultimately, death.

Free radicals are molecules within the human cells. Due to regular oxidation (e.g. breathing), and other environmental factors (e.g. tobacco smoke), these molecules become damaged and unstable, and begin to affect other healthy cells close by, creating many more similar unstable free radicals, and thus initiating a chain reaction of cell damage by free radicals.

Damaged cells lead to disease and ultimate death.

The genetic theory of aging

This theory is based on the pre-programming of human genes to induce aging and death—your Creator ensures that you will not be immortal. Therefore, aging is not the consequence of wear and tear over the years. The fact of the matter is that you are not meant to live forever.

Other than disease and other environmental factors, there is no great variation in the lifespan of humans, and this may partially explain the role of genes in aging.

The hormone theory of aging

This theory is based on the gradual changes in the human body due to the decline and degeneration of the endocrine system, which is responsible for producing hormones to regulate many body functions and processes. Changes in the human hormone production, such as menopause, account for the changes responsible for aging.

The immunity theory of aging

This theory is based on the failure of the immune system to give adequate protection against contaminants, viruses, and stress, among other agents contributing to a weakened or compromised immune system.

This theory attests to the important role of the immune system in longevity health and overall wellness.

The rate of living theory of aging

This theory is based on the rate of breathing: faster oxygen metabolism leads to a shorter lifespan. In the animal kingdom, rodents, with the fastest heartbeats have the shortest lifespan, while tortoises with the slowest breaths live the longest.

This theory vindicates that breathing right is one of the key factors in longevity in humans. Learning to breathe right is critical to remaining younger and healthier for longer.


To sum up, the human aging process is best explained not by one single theory but by a combination of these theories.

Apply the theories of aging and live to 100 and beyond. But no matter how long you may live, get the wisdom of happiness and live as if everything is a miracle.
