In the words of Aldous
Huxley, "The knowledge that every ambition is doomed to frustration at the
hands of a skeleton have never prevented the majority of human beings from
behaving as though death were no more than an unfounded rumour."
Karin Knorr Cetina (page S76 ) cite the issue of consumer exploitation on anti ageing as a segment shrouded with an aura of science. “The use of human frailty for commercial exploitation is also singled out as a deplorable characteristic of the present-day anti-ageing medicines and market” as quoted from works tabled by McConnel & Turner.

Compressed Morbidity aims at preventing old age related disease, a paradigm relating to intervention in ageing processes at the molecular level to slow the process down. This desire or thought relates thus to life span increase. It is also the most fundamental or conventional one.
Decelerated ageing aims to slow down all fundamental cellular processes of the human body so as to raise the average life span and life expectancy levels overall.
Arrested ageing the most ambitious of all seeks to cure ageing by separating and doing away with all the remnants of damage caused by metabolic processes so as to be able to constantly maintain the vitality and bodily functions.
While the US and France have planned studies on ageing and further research on compressed morbidity approach, basic science has already established that life is a form of metabolism and has its own set of causes and effects, waste effects, lay byes.

While many search for the proverbial mountain of youth, the
mass quest has been hovering around the question why do we age at all ? What is
it in our bodies in the shape of continual chemical processes or biological
protocols that causes us to grow old. There are a plethora of internal and
external factors such as diet, exercise or environmental stress and they all contribute
to cell damage and affect the rate of ageing, but the truth is that we have a
biological clock buried deep within our genetic make up. This clock can only
run for so long, in other words we are programmed to die.
Our bodies are made up of trillions of cells, countless
perhaps, which are constantly dividing and each time it happens the cells make
a copy of their DNA as well or replicate themselves. This DNA is tightly packed
into structures called chromosomes. Characteristics and genetics passed on down
the generations or racks of sets of chromosomes is dependent on these
structures. Humans have 23 pairs of chromosomes. While the DNA replication
isn’t quite perfect it skips over the end of each chromosome or at ends is a
kind of incomplete process. To protect against important DNA information from
being cut out due to this incompletion or imperfection of the process of
replication, chromosomes are equipped with “telomeres” on their ends which are
essentially meaningless repeat of DNA, something similar to temp files being
created while working on a system which we can afford to loose. However, each time these cells divide and
replicate, these “telomeres" become shorter and shorter until eventually
they are entirely stripped away at which point the cell ceases to divide
further and eventually dies. In the absence of this shortening of telomeres
life could have been eternal and never ending.
Some organisms such as flatworms have the capability of
regenerating unlimited telomeres hinting capability to be actually immortal,
however disease, infection and environment equals them out with the rest of us.
This suggests that aging is related to biological and environment factors. Why
don’t our cells replicate telomeres. Ultimately this replication limit actually
helps to prevent diseases such as cancer, which is the uncontrollable growth of
cells and evasion of cell death.
The point at which a cell stops replicating is known as
cellular “senescence.” The causes of senescence and possibilities of delaying
or avoiding altogether is the basic tenets of all researches world over.
Human cells can replicate approx 50 times in their lifespan
and once it is reached the cell gradually begins to loose it’s function and
die, displaying age related characteristics. This also helps to explain why
life expectancy is a trait which is inherited down generations through genes,
since parents and generations further gave us the length of our telomere and
the traits of a timeframe as well in which the entire cycle of a chromosome or
cell or telomeres would be run.
Gerontology emerged as a science in late 19th
century and seeks towards attaining answers and extensions. Technological
innovations have increased life expectancy as better sanitation, clean water,
effective prescriptive drugs availability and better medical and health
services have all contributed to increasing life expectancy worldwide. However
still we are able to see a global inequality in terms of infant or at birth
mortality rate which is a cause of worry still, both in developing and done
with nations.
Ageing has been studied and gazed upon by all cultures and
civilizations. Immortality has been longed for by all generations and compared
to salvation or moksha. Ranging from Indian mythology to Chinese folklore, mentions
of immortality are rampant across times prestine, There are abundant chinese medicine which stake high claim on
ageing slowing medications and potions for enhancing longevity. In the West ageing
has been approached through evaluations done scientifically as exhibited in the
studies and works of eminent authors and researchers. One such study by
Christopher Hufeland, a German physicist, refers to “protocol for life style
and diet to increase life expectancy.”
As the population of the modern world entered old age and
experienced degenerative old age related diseases, demand for anti-ageing
options increased and the anti ageing industry grew in leaps and bounds with
it’s cart of offerings. The growth happened similar to alternate medicine, where
the segment has thrived on using scientific principles and fundamental theories
symbolically and in an ambiguous, opportunistic way, to present their case and
at the same time lay no claims on proven experiments which authenticate their
claim. In the garb of rationale reasoning that science offers and yet
maintaining distance from clarity, these products continue to grow and the segment world wide has contributed
each year to the GDP. Whatever may be the case the population needs a remedy.
Government released articles make profound mention of anti ageing
products and the industry and state the anti-ageing consumer industry to be a
sizeable one, full of all types of products at all price levels catering to all
segments, such as yoghurt based potions, enema regimens, cell injections,
magnetic devices, skin creams, herbal elixirs, glandular extracts, hormonal
therapies, vitamin supplements, fad diets and exercise programmes. These
products offer anti-oxidants to neutralize oxygen-free radicals; chelators to
bind heavy metal ions such as copper and iron; dehydroepiandrosterone to
rejuvenate the immune system, improve brain function and relieve stress; growth
hormone to increase muscle mass and function; retinoic acid to decrease skin
wrinkling, and many more. The grandeur of promises being made have been
strongly objected of late by the scientific community due to the lack of
experimental and clinical data to support effectiveness of the drugs and
especially their high side effects.

At present, it appears that the only way of significantly
extending human lifespan is with
Caloric restriction. However, there are a number of factors,
which seemingly can improve
lifespan.
Since ancient times, humans have been concerned with developing and preserving
youthful
vigor, stopping the running age clock, and extending lifespan.
Today there is a great progress in
understanding the aging process in attempt to delay it. Harmone
replacement therapy (HRT) has emerged as the new science and therapy for many
disease preventions including ageing. The therapy entails using
popular and easily obtainable hormones: estradiol, testosterone,
DHEA, thyroid hormone,
melatonin, growth hormone, and progesterone to control or
regulate harmone levels in the body which further impact the risk of diseases
such as cardiac,cancer,process of ageing etc. Many of the benefits of using
these hormones are equivocal thus far, but we are seeing an increasing number
of studies which, at least, recommend these hormones as viable therapies to
slow down the aging process, to stop the development of agerelated diseases,
and to stay vital and fit in the second half of life.
In the Indian context life extensions have been claimed by many
gurus and yogis who underwent rigourous penance and meditation and attained a
higher form of existence with slowed metabolism and control over aging. These
ascetics were known to eat or drink almost neglible and even control their
breathing to slow down the demands of the body and impact longevity. The
concept although stemming out of spiritual realms has it’s roots embedded in
the very scientific principle of slowing down the metabolic rate of the body
thereby preserving the telomeres from getting stripped faster.
By adopting a more practical and do able approach to extension
of life spans, meditational practices, organic eating without a coat of
insecticide sprays, abstinence from life shortening vices such as smoking and
drinking and leading a simple stress free existence, we have a better chance of
surviving longer and see the sun shine on our eightees and ninetees and on our
progeny too.
The quest for immortality however shall continue within our
curious minds as we remain unquenched. As King Crimson says it “ confusion will
be my epitaph, as I crawl, cracked and broken.”
As the great rock kings The Rolling Stones sum it all up aptly in
their song “ Time waits for no one and it won’t wait for me.”
