PEOPLE who proved to have longevity of certain genes are inherited. Still, can not be medically determined who those people will live long or not.

Human age is the biggest secret of the Lord. However, there is no harm in us as humans try to "extend" because God Himself is still giving the opportunity to change the destiny of mankind. Medical science has long been know the various tricks and methods to slow aging.

It turns out that because of daily habits that affect health. Breakfast habits and climbing stairs for example, without your awareness contributing to improved health. This custom seems trivial, but over time, the benefits of small habits like this will be collected. Thus, by maintaining healthy habits, you can extend life expectancy.

However, a number of scientists from the United States who conduct research related to family genealogy and lifestyles has found a gene that "responsible" in human longevity. They get people who live to 100 years or more turned out to have similar genes. Accuracy of this invention achieve 77 per cent.

In research published in the online edition of the journal "Science" on Thursday (1 / 7), researchers trying to understand how people survive to old age. In its report, the same number of genetic variation found within themselves.

Although genetically related, do not immediately stop your efforts to diet and exercise. Not that this research can determine who those who can live long or not. Because, according to T Paola Sebastiani and Thomas Perls of Boston University, the United States that included in the research team, a healthy lifestyle and other factors are also significant in affecting longevity.

Perls said the possible results of this study can detect anyone who would be more susceptible to certain diseases. Or, it could be helpful to guide therapy for those processes. In this study, researchers looked at 1055 genes from people of Caucasian race who were born between 1890 and 1910, and compared with 1267 other people who were born later.

By studying the genetic signals, the researchers finally able to predict the same groups of genes derived from persons aged 100 years or more, with an accuracy up to 77 percent. "A sum of 77 percent accuracy is very high for the same genetic model," said Sebastiani. "But there's 23 percent error rate and show that there are many things remain to be discovered," he said as quoted by the Associated Press.

Apart from the environmental conditions and a person's health history, this gene proved to be capable of working in a complex to provide longevity. Researchers named the unique model includes 150 genetic variants called single nucleotide polymorphisms (SNPs).

In the study, participants were divided into 19 groups with different genetic mark that is found in their bodies. Several genes have a correlation with longer survival, while other genes that function delaying the emergence of age-related diseases such as dementia.

"We find the fact that what affects longevity is not lack of regard for many diseases, but the presence of a protective variant," he said. In addition, 40 percent of seniors over the age of 110 years it has three specific genetic variants the same. Perls reminded that this matter is that the genetic puzzle is very complex.

"We're still, medium, and kept going to find out what patterns of new genes regulated by this," he said. "I see the complexity of this puzzle and felt that (the research) will not lead to treatments that will make people live long," he said.

But, he added, this research can assist in developing strategies and tracking that will help you find what treatment will be needed to prevent the threat of disease. The study, which began in 1995 it was only focused on people with Caucasians.

"So, the cause of longevity has been revealed. It turned out that genes also play a role, "said Dr. Kenneth S. Kendler of the Department of Human and Molecular Genetics at Virginia Commonwealth University, USA.
