Over the past century human life expectancy has been increasing by leaps and bounds. In 1900, the average lifespan was around 50 years, while now it's closer to 80. But while the average age is still increasing, the maximum age has pretty much leveled out. The longest-lived people typically live to around 115 years, and that number hasn't changed since the 1990's.
According to the researchers, this suggests that no matter how advanced medical technology becomes, we'll never be able to live past 115 or 120 years old. However, there is some disagreement from other scientists, mainly that the researchers are underestimating the life-extending ability of modern or future medicine.
Other scientists have managed to dramatically extend the lifespans of certain animals like mice and flies in the laboratory, and there's no immediately reason why we won't be able to do something similar for ourselves in the future.
While it may be impossible for people to live beyond 115 years or so at the moment, it may become possible with genetic treatments or other technologies in the future. So don't necessarily give up your dream of living forever just yet. Worst case scenario, maybe you can just hop into a robot body instead.
