Everyone experiences aging. But somehow it is still a mysterious phenomenon that no one can understand completely. It involves a set of organic changes taking place in the body over the years that it's hard to pinpoint aging as a single event.
It may help if you think it this way. Every organic living is much like a substance. It has a shelf life. Food can go bad over time, just like our body can decline in performance, productivity and health. An unopened bottle of instant and commercial coffee may have a shelf life of up to a year. To get the maximum shelf life, care should be taken to comply to the recommended storage practice. That doesn't mean with care it can escape its shelf life. For beaufort cheese, mold may develop. Or it may eventually become crumbly and lose some of its flavor. Why?
Food products, like human body, exist under specific conditions. With an exception though. Beyond its shelf life, food composition will change. Conditions can only help achieve its full life. Failure to comply will turn the food foul before its time.
The shelf-life of human being is over 100 years. However, the genes, environmental influences and lifestyle can seriously modify life expectancy of a human being. Nowadays, on average life expectancy of human being averages around 75 years. Besides many obvious reasons like air pollutants, economic circumstances and access to medical care also affect life expectancy.
There are also internal factors. Gene factors passed down by generations of family history also determine the aging rate. How fast people age varies from one person to another. Hereditary traits play a crucial role in that.
Around the age of 30, aging process begins to take place. Hereditary traits, which are determined by specific genes, begin to develop as the body's preparation is reduced. At the same time, when immune function is reduced, various disorders begin to develop readily.
Aging begins to occur after the body stops developing. And the rate of which it occurs will only grow rapidly as time goes by. What happens to our bodies over time, deterioration of the body tissues, etc., as the result of wear and tear, is defined as aging.
Effects of aging are common in every human being, although the speed of aging may be different. In order to preserve our bodies, it is important to identify we age before tackling on the specific issue.
