Aging is a Combination of Factors--Some are Unknown

 It is not known with certainty. But there is reason to believe that it is related to heredity and wearing down of body parts. There are several scientific theories about what is driving  aging. One theory that is most strongly held  is that our genetic material controls aging. That is, we almost have  a kind of biological clock that is ticking away our life.

- It's a known fact that members of some families live long and suffer from few diseases. In other families, the life span shorter ...

- Yes, and it strengthens the assumption that genetic factors are crucial for aging mechanisms. It has been speculated that one can extend the human aging process and life expectancy with genetic engineering. But I think the little ones. Among other things, because there is a aldringsgen, but many - very many aldringsgen.

Are aging and disease two sides of same coin?

Disease is more common among older than younger people. Much of what people take to be age symptoms are actually disease. But it is important to distinguish between disease and normal aging, as the disease often can be treated as you become more fit again.

The aging process  leads eventually to reduced reserves and reduced emergency response in the body. This means that the risk of disease and injury increases, while the ability to survive illness and injury goes down. 

In the old we find that age deterioration can follow  a course where something starts out as a slight infection progresses to a serious condition with multiple organ failure, such as heart failure, hypotension and renal failure.

Can medications delay aging?

 Especially in countries with weak or no-drug control, there are many products marketed as remedies against aging. But no drugs have proven efficacy. 

A real "rejuvenation pill" is yet to be discovered. Because we do not know what controls aging, we have no resources that can completely stop it.  To be sure there are marketed a range of products, especially the health food industry, which claim to prevent aging. These products have questionable value.

Yes, to some extent. People grow old in slightly different speeds. This is partly determined by heredity, but also to some extent on how you manage to counteract the aging process.The best advice is good nutrition, ample exercise and sunlight, to avoid environmental toxins such as tobacco and other harmful substances and to provide plenty of mental and social activity.

Age and wisdom

 Age and wisdom belong together naturally 

Indeed, there is much wisdom among the elderly. One aspect of psychological aging is the security and dignity older people often have, which is built on long experience of life. Life Experience and psychological ballast is of great importance for how the mind and the soul fare  in old age.  The differences in thoughts, feelings and intellect is greater in the older person than in any other group of the population.

Interviews with older persons have shown that the following points are important:

• Health 
  - Physical (absence of disease and disorder). 
  - Mental (a harmonious mind).
• Safety 
  - Economically. 
  - Rights (due process). 
  - Physical (protection from violence, crime and accidents).
• Freedom 
  - Independence and self-reliance. 
  - Economically.
• Beauty 
  - Art (visual art, music, literature, dance, etc.). 
  - Nature.
• Faith - belief. 
  - Religion.
• Love and relationships with others
