Aging is difficult to define, but you will know it when you
see it or experience it yourself. In brief, 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 begins as early as from young
adulthood (around age 20 to 40) to middle adulthood (around age 40 to 65), and
continues to old age (beginning at the age of retirement, approximately at age
65). 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.
The hard facts of aging
Whether you like it or not, your biological clock is ticking,
and this will happen to various systems in your body:
Your
heart will pump less blood, and your arteries will become stiffer and less
flexible, resulting in high blood pressure—a health problem that often
increases with age.
With
less oxygen and nutrients from the heart, your lungs will become less efficient
in distributing oxygen to different organs and membranes of your body.
Your
brain size will gradually reduce by approximately 10 percent between the age of
30 and 70. Loss of short-term memory will become more acute.
Your
bone mass will reduce, making it more brittle and fragile. Your body size will
shrink as you lose your muscle mass.
Your
biological clock is ticking, whether you are conscious of it or not. Your mortality
has been pre-programmed into your biological organisms and you body cells. Theoretically,
you may have an indefinite lifespan through their division, rejuvenation, and
regeneration—if they are still healthy and functional. Although your genes may
have pre-determined the speed of your biological clock, you can still slow down
the speed of aging—if you still have good health.
Slow
down, if not stop, your aging process with good health. So, what is good
health? Is being healthy synonymous with absence of disease?
According to the United States Public Health Service,
good health is “preventing premature death, and preventing disability,
preserving a physical environment that supports human life, cultivating family
and community support, enhancing each individual’s inherent abilities to
respond and to act, and assuring that all Americans achieve and maintain a
maximum level of functioning.” This statement probably sums up what you need to
do in order to be younger and healthier for longer; it says everything
about aging.
The
truth of the matter is that you age, just like everyone else. The point in
question is how you can delay that
aging process, making you younger and healthier for longer—or, at least, not
making you age more quickly than you are supposed to.
To
live a longer life and to defer, if not totally avoid disease, you must live a
stress-free life. Living in a complex and compulsive world, stress-free is difficult
but not impossible. Stress originates from your perceptions of what you are
experiencing; it is all in the mind—your
mind. Stress stems from your attachments in the physical world that define who
you are, or rather your ego-self. Let go of your attachments, and you have no
ego and no stress and live as if everything is a miracle.
