When Does Aging Begin ?

The time span between birth and death wherein the body undergoes changes is termed as aging. Aging begins the moment an individual is born and ceases when the individual dies. The aging process undergoes various changes as a person progresses from childhood to adulthood and then turns old. (See Reference 1)



Although science has made tremendous advances, till now it has been unsuccessful in measuring the biological age of human or any other animal. The process of aging is primarily carried out by two important biological functions. One is genetic and the other is cellular function. As aging progresses, the waste products begin to accumulate in the cells. The elasticity of the connective tissues also begins to reduce.

These changes at the cellular level are responsible for majority of the physical and sensory weakening that people experience. The metabolic waste products result in building up of an insoluble fatty substance known as lipofuscin. When this substance accumulates in large quantities, it is known to adversely affect the functioning of cells. (See Reference 1)

The next biggest factor responsible for aging is the loss of elasticity in the connective tissue. Collagen makes up more than one-fourth of the human body’s protein. Changes in the level of collagen are responsible for decline in the elasticity of the connective tissues. Biological aging occurs slowly, and as it progresses, the individual learns to adapt to these changes. One of the most interesting facts about humans is that they have the ability to adapt to different changes, be it environmental or biological. Perhaps, that is why aged people also want to remain independent despite physical limitations. (See Reference 1)

Aging Associated Diseases

Aging Associated Diseases      Aging associated diseases are quite different as compared to ageing itself. These diseases are actually the ones whose frequency of incidence enhances as one ages. Each human being on this planet is bound to age. However, not all of them suffer from aging associate diseases. A lot depends on the lifestyle of an individual. An overall healthy adult with moderate healthy lifestyle might not suffer from any of the aging associated diseases. (See Reference 1) More..
