In this material, we would like to describe in simplified form the causes of ageing and mortality, which are the subject of modern scientific concepts.
There is widespread and firm notion among most scientists that real general potential of human body is near 120 years. We do not take into consideration different statements about 300-500 human life term because of the lack of scientific background under these assumptions. General science is also passed the time of euphoria in gerontology and geriatrics (studies about treatment of ageing) which was climaxing in 60-70 years of 20 century. In that time, such prominent and respected organization like RAND Corp forecasted increase of the human life span for 50 years until the year of 2020; Smith&French Corp anticipated the same results achieved by the middle of nineties, and there were many others not mentioned here. As we can see, time goes on, but the prognoses are not realized and there is no major breakthrough in this sector, despite of great number of discoveries in traditional medicine.
If we exclude cases of death from accidents, the main reason, which leads us to death, is senility, or in other words, the speed of ageing. In addition, the main reasons, which causing and influencing senility or speed of ageing, are diseases. Or else, it's better to say that people are dying not from ageing, but from diseases, from which ageing realizes itself.
As a rule, scientists define three core types of such illnesses, which directly correlate with ageing and usually lead people to fatal end. These are cardiovascular, immune or endocrine system diseases. They actually determine illnesses such as: atherosclerosis; ischemic heart disease and ischemic brain edema; cancer; diabetes; and parkinson's. In the case of accelerated ageing, these diseases appear earlier and proceed fast. If it is the case with slow ageing, the diseases usually appearing late.
Perhaps, for young people the names of these diseases mean nothing and they never heard about some of them before. However, if they inquired about the reasons of the death of their relatives, they would be surprised to hear one of the above-mentioned diseases.
Here, a brief observation of causes, which provoke these diseases is presented
(please click on the link to open description table). They are: style of life, recrements storages, genetic, hormonal, mutative, cells necrosis, vascular and switching factors.
Most of the above-mentioned approaches are consistent with the fundamental approaches of gerontology. Mortology is directly interesting and try to research deeper some of these approaches.
From the other hand, social gerontology, as a science about problematic aspects of interaction between seniors and social environment, is also very important. In the United States, this approach of gerontology usually associated with geriatrics, which in general refers to questions of rendering of medical services and assistances to seniors.
The demographic situation in the United State and Europe is characterized by rapid growth of aged people. Although, in science there is no consensus about opinion on gradation of aged person, most scientists consider that:
- from 61 to 75 is the group of elder persons;
- from 76 to 90 is the group of senile persons;
- from 91 and up is the group of long-living persons.
However, these data also have to be compared with the real biological age of the person. The difference in calendar and biological human age are directly connected with the speed of ageing, and is specific and individual for every person depending on the factors listed above.
The methods, by which we can find biological age of the person, are most difficult to define. One of the approaches is to determine the total of personal dynamic diseases and compare them with the average rates of same age group. Sometimes difference between biological and calendar age can reach 10-20 years. As a rule, the main reasons of early ageing - progeria - are such diseases as: pancreatic diabetes, chronic infections, arterial hypertension. To help the body resist early or accelerated ageing, medics use all complex of geroprotraction instruments, which include medication treatment as well as prevention therapy. Among medications, there are broad group of geroprotraction pills, which based on antioxidant products, various vitamins and dietary supplements, and special antidepressants. Prevention therapy, as a rule, is based on healthy style of life, prudent nutrition, reasonable physical training, and active socialization.
We hope, that this brief observation will attract your attention and will help you to be more competent in above mentioned questions. Our next materials will be devoted to particular gerontological problems and will describe simple methods, which will help you to keep your body healthy and stay young longer.
