How much time do we live today?
People today are aging and aging. But how old can we become? The researchers have now discovered that we humans are far from having reached our final life expectancy.
Researchers at Sapienza University in Rome and UC Berkeley found in their current research that humans have not yet reached their last life expectancy. In the future, people will probably grow old. The doctors published the results of their study in the English language journal Science.
What is the risk of death in old age?
For the current study, the risk of direct mortality has been studied. Experts have found that after the age of 80, the immediate risk of death begins to decrease. The researchers found this in a study of 4000 subjects from the United States and Italy. Once a person has reached the age of 105, the risk of dying remains high, suggesting that the probability will persist for at least 110 more years, say the experts.
What makes life expectancy longer?
If people were born before 1910, it was very unlikely that they would reach the age of 96 years. Nowadays, the chances of being over 96 years old are much greater. While our growing longevity is often attributed to advances in medicine, the experts who conducted the study believe that it's just a proof that humans are evolving through selection natural and become much older in the future.
There seems to be no limit to life expectancy in sight
Recent research suggests that the expectation of human life is still prolonged, and people who reach age 105 have a good chance of surviving for at least another five years. Data from the survey show us that there is still no firm limit to human life in sight, says UC Berkeley Professor Kenneth Wachter in a press release [19659011] Experts have studied 3,836 Italians for study
the study quite controversial. Demographers have not agreed for years to know whether the mortality rate increases steadily with age or declines at a given time, as is the case, for example, for animals laboratory like fruit flies and worms. The current study is hailed as one of the most comprehensive studies on life expectancy and mortality risk. For their study, the researchers studied the data of 3,836 Italians (3,373 women and 463 men), who were born between 1896 and 1910 and reached the age of 105 years. Unlike most other countries, Italy (which has the second largest number of centenarians in the world after Japan) asks citizens to report on their well-being every year.
110 years old, the risk of dying reaches a plateau
The study showed that people aged 105 to 109 years old had only a 50% chance of dying in the year. One could expect an additional lifespan of at least a year and a half, say the doctors. Scientists were surprised to find that the same statistic applies to 110-year-olds, suggesting that the risk of death no longer increases. This is a clear indication that people are evolving to have an even longer average lifespan, the authors explain.
The results criticized have been questioned
Of course, the results have been questioned by some experts. who are of the opinion that there is a limit to human life. For example, a study published in 2016 concluded that we have already reached our maximum life cycle. (As)
