An inevitable change:
The process of aging is the inevitable change in the organisms.
And according to the practitioners of Ayurvedic Massage
the process of aging involves multidimensional process of
psychological, physical and social change in the environment. Some
of the researchers in the world refer aging as a disease in
gerontology i.e. certain genes with a certain pattern of subdivision
of cells that affects ageing.

Catabolism and Anabolism
What practically happens is as individual progresses in life so
the process of loss of tissue which is termed to be catabolism is greater then the process of gain of tissues which is known to be
anabolism. As a result of which the strength and immunity start to
decrease.
Different Theories of aging -
There are different
theories of aging which is mentioned below:
a) Theory of free radical:
In a free radical theory the free radical is any atom or molecule
which has a single unpaired electron in the outermost shell . And
according to this theory the process of aging is actually when cells
start to accumulate free radical damage over time.
b) Telomerase Theory:
This theory which was first discovered by group of scientist in
Menlo park at Geron Corporation located in California. So basically
telomerase are sequences of nucleic acids that extends from the ends
of chromosomes and which basically have the ability to protect the
chromosomes inside our cells. Each and Every time our cells divide,
the telomerase become shorter and less able to protect the
chromosome. This is the basic phenomena behind the destruction of
cells.
c) Hayflick Limit Theory:
This theory was discovered by Leonard Hayflick. And according to
this theory the population of cells in a cells culture divide between
40 to 60 number of times. So eventually when the process of mitosis
occurs its shortens the telomerase. As a result of which further cell
division becomes impossible which correlates with the process of
aging.
