Researchers recently published an article in the Journal of Nature stating that we, as humans, may have reached the upper limit of longevity. Now, although it's no secret that one day we all must cease to exist, it is most certainly debated as to when that is going to happen. The New York Times Well Blog recently featured an article discussing the new journal publication, and some of its surprising facts. The article states, " In 1968, the oldest age attained was 111. By the 1990s, that figure had increased to around 115. But then this trend stopped, too. With rare exceptions like Mrs. Calment (shown on the left), no one has lived beyond 115 years." The jury is still out regarding the upper limits of human age, but it's always great to see cases of people living over a century with such high quality of life. See what you think about the rest of the article at the NYT blog.
