"The statistics are not enough to say that you can not live longer than that, according to the data we have," said the report's author, Siegfried Hekimi, president of the developmental biology at McGill. "Wakter and his colleagues followed the death trajectories of nearly 4,000 Italian residents who reached the age of 105 between 2009 and 2015.
Investigators discovered that:" This is not enough. "For example, Italian women having reached the age of 90 had a 15% chance of dying in the year and an additional life expectancy of six years on average, however, as they reached 95, their odds of dying within one year increased to 24% and their life expectancy dropped to 3.7 years.
One would think that these chances would continue to increase indefinitely, l & # 39; 39, age to an undefined vanishing point.
This is not what happened, however. The chances of survival have rather capped once people have exceeded 105.
"The risk of death is very high at age 105, but next year it's not higher, "Hekimi said of the new study." Every year you have the same chance of dying, and every year you can be the one who wins the draw. "
This plateau probably occurs due to the evolutionary selection and l 39; influence of good genes and healthy lifestyle choices.
"When you look at a group of seniors who are all the same age, some are already quite frail and others are robust, there is a big difference in the level of frailty," says Wachter. who are in your fifties, you look around and some people climb mountains while some people walk with canes … Now, 15 to 20 years later, people who were already fragile are those who are likely to 39, be dead, "he said.
Not enough participants in the study
Up to now, examining the genetics of people with a long life span has provided tremendous clues about the prolongation of human lifespan, Hekimi said.
