First, though average levels of many physical functions show a progressive decline with age, there is a wide variability within aged groups. Some individuals show no decline at all. The fact that these individuals exist indicates that chronological aging is not an inevitable cause of biological aging
Often a person will blame a health condition, such as a bad shoulder, a bad knee, etc on their age. But if age were to blame, then it would stand to reason that both shoulders and both knees would be degenerated and not just one limb. These problems are due to cumulative stress and traumas, not to the passage of time.
The second line of evidence that aging is in fact degeneration caused by abnormal stress is the continuing discoveries that aging process previously considered natural do not occur at all in some human populations. Blood pressure for example, rises with age in the American population, and it used to be considered an inevitable part of aging. Science knows now, however, that there are numerous populations, mostly isolated from Western society, in which the elderly have the same blood pressure as the young. Science has known that rising blood pressure is caused by complex factors in the environment of Western society. When members of populations migrate to western society, their blood pressure begins to rise with a few years. Also, osteoporosis is a major health concern for western women; however, women in other cultures around the world do not suffer from osteoporosis and similar degenerative disorders.
So the next time you think that some disease process or ache and pain that you have is part of the “normal aging process”, think again.More
