While the average life expectancy for Americans currently stands at 78.7 years, results from a new study conducted by a team of researchers from Europe and the U.S. suggests that there’s no limit on how long people can live.

In the study published Thursday in the journal, Science, researchers examined 3,836 Italians aged 105 and older between 2009 and 2015 and found that after age 105, the risk of dying remains the same.

“We observed level hazard curves, which were essentially constant beyond age 105. Our estimates are free from artifacts of aggregation that limited earlier studies and provide the best evidence to date for the existence of extreme-age mortality plateaus in humans,” the researchers said in an abstract of their findings.

Kenneth Wachter, a professor of statistics at the University of California, Berkeley, who is co-author of the study, explained to AFP that: “As we age, our health and risks of death get worse faster and faster. But at extreme ages, they stop getting worse. They don’t get better, but they stop getting worse. They level out — it’s called a plateau.”

The study also looked at mortality among people born in the same years…
