Guessing the answers of longevity mystery

Some time ago, the world is shocked by the presence of Mbah Gotho in Sleman, Indonesia is very old. If the documentation of his was proved to be correct, then the 146-year-old grandfather was the oldest man on Earth. Beside that, Mbah Gotho known as heavy smokers, so the secret of longevity of his became a mystery.

Are there other factors that determines the human's life expectancy? From an international study conducted by the researchers at University of California Los Angeles suggests that the life expectancy of most humans is influenced by genetic factors, regardless of a person's lifestyle choices.

The study was led by a geneticist named Steve Horvath of UCLA and worked together with 65 other researchers around the world. The study was conducted through the analysis of blood samples taken from 13,000 people.

As quoted of UCLA on Saturday, October 1, 2016, that the epigenetic 'clock' previously developed by Horvath used to calculate the aging of the blood and other tissues in the human body through the tracking of DNA changes in accordance with the passage of time.

These 'clock' is able to calculate the biological age of blood. According to scientists at UCLA, the biological age is superior than chronological age in terms of determining when the time of someone dies.

The research results have been published in the Aging journal refers to the 13 sets of data. According to Horvath, a healthy eating habits combined with exercise had no impact on delaying death in some people.

"We found that about 5 percent of the population gets old with higher biological speeds, so that life expectancy is shorter," Horvath said via a press release.

"An aging accelerated process to increase the risk of death by 50 percent of adults at any age level." But, the study leader added that the risky activities such as smoking still can accelerate the aging process, although genetics plays a much stronger role.

Horvath continued, "Although a healthy lifestyle could add to life expectancy, the aging process that is within preventing us continually outsmart the death. However, the risk factors such as smoking, diabetes, and high blood pressure are still strong predicting the death rate (mortality) compared to the speed of someone epigenetic aging."

Even with these findings, but the perpetrators of the medical profession looked at the ability to predict the life span by using epigenetic clock as something that is still uncertain. "Is the epigenetic changes caused by chronological aging directly cause of death on the older people?" said Dr. Themistocles Assimes of Stanford University.

Dr. Assimes, who is also the author of the research report, furthermore said, "Maybe the change was simply to encourage the development of some kind of disease or undermine the person's ability to resist the development of the disease after being exposed. There is still need of future research to answer those questions." *** [EKA | FROM VARIOUS SOURCES | UCLA | LATEST TECHNOLOGY]
