What is Aging

Aging in humans refers to a multidimensional process of physical, psychological, and social change. Our interest here shall focus on the Degeneration of Physical body - the cells. Accumulation of cellular damage - more cells are being damaged than the body is able to repair or replace. Resulting in having aging symptons which include:

  • Thinning and graying hair
  • Wrinkling of the skin
  • Slowing metabolism
  • Decline in sexuality/ Reproductive ability
  • Lose of muscle strength
  • Decrease in bone strength and density
  • Decline in breathing capacity
  • and etc

There are several Biological theories such as Aging-Clock Theory, Cross-Linkage Theory, Error Accumulation Theory, Evolutionary Theories, Free-Radical Theory, Reproductive-Cell Cycle Theory, Somatic Mutation Theory, Wear-and-Tear theory and more.

Aging occurs when cells are permanently damaged by continual attacks from chemical particles called Free Radicals - Free Radical Theory. It does not explain many of the mysterious processes of aging, however many authorities believe it explains a major part, of which leads to death - the ultimate consequence of aging.
