If you wanted to live until, say, the year 2140, don't get your hopes up. A new study from the Einstein College of Medicine found that human beings' maximum lifespan is about 115 years, NBC News reported.
Jan Vijg, a genetics professor who was an author of the study, said his team looked through global databases on lifespans and found improvements in mortality peak at the age group of about 100 years.
"We show that improvements in survival with age tend to decline after age 100, and that the age at death of the world's oldest person has not increased since the 1990s. Our results strongly suggest that the maximum lifespan of humans is fixed and subject to natural constraints," the study said.
While the idea that humans cannot live forever isn't new, it wasn't always easy to back it up with evidence. But with countries keeping better records, Vijg said it's easier to find data to back it up.
