Aging is a continuous process that begins at birth and continues throughout all
stages of life including childhood, puberty, young adulthood, middle and late ages. In
this article, we divide aging into two groups: healthy and unhealthy aging. Healthy
aging is not accompanied by disease and disability while unhealthy aging is associated
with the common complex of diseases and impairments. People who age healthy do not
experience many of the unwanted features of aging, such as extensive tooth loss.

When we get older our body changes in many noticeable ways. Often, the first signs
involve the musculoskeletal system and then sensory organs. One day, we may find
that we can no long focus easily on close objects or loss the ability to hear the highest
pitches. Some of us by late age may find that their favorite pants do not fit them
anymore, as their body fat increases a lot at their abdominal region. Our skin also
becomes thinner and wrinkled. Our internal functions also decline with age. Luckily,
most functions remain adequate throughout life. Disease, rather than healthy aging,
usually accounts for function loss in old age.

S. Jay Olshansky, PhD at University of Illinois at Chicago said,"What we should be
pursuing is way to slow down the biological process of aging rather than stopping it...If
we succeeded in delaying aging the bonus would likely be an extension of life." in a

MAN at 40

Study shows that the brain function starts to slow around age 40. Dr. Bruce Yankner
from Harvard Medical School has already identified the genes which play the key roles.
Because of the wide differences in gene activity among people, individuals may
approach a stage of "old age" at different rates.

Obesity, a major risk factor for diabetes, affects 300 million people in the world and
about 194 million people suffer from diabetes. By 2005, the number of obese people
may soar to 333 million. Professor Claude Bouchard, International Society for the
Study of Obesity, suspected that within a short period of time we would see a reduction
in life expectancy because of the twin epidemics (obesity and diabetes).

Why walking? Walking is an exercise which has a low injury rate. You can walk at a
pace as you like. Walking improves circulation and stretching decreases the buildup of
lactic acid.  Extracted from: Health Tip: Seniors Who Walk for Exercise, HealthDay,

There is another reason for walking-a prevention measure against erectile dysfunction.
Researchers studied some 31,000 men between ages 55 to 90 and concluded that
men who regularly exercised typically had a 10-year delay in erectile dysfunction.
Sedentary men may be able to reduce their risk of erectile dysfunction by performing
exercise at a level of at least 200 calories a day, which corresponds to walking briskly
for two miles. Source Daily 2-Mile Walk May Prevent Impotence, by Sid Kirchheimer,
