Humans Have A Limit To Our Lifespan, And We've Reached It, Say Scientists
Apparently 125 years is the maximum we're getting.

Life expectancy appears to be ever-increasing. While in 1900, the average life expectancy was just 50, a baby born today can expect to live until 81. However, if you assumed that there was no upper limit on our possible lifespan, then think again—scientists think humans are unlikely to ever reach an age above 125. Despite huge advances in medical science, a new study suggests that there is a ceiling to our upward trajectory, and that we have, in fact, already reached it.
Scientists at the Albert Einstein College of Medicine, in New York, believe that human life expectancy probably peaked in 1997 with the death of the world's oldest woman Jeanne Calment, who died age 122. In the decades since, the age at which the oldest people died has been more around 110, with nobody beating Jeanne's record. The oldest person alive today is Emma Morano, an 116-year-old Italian lady who was born in 1899.
The researchers believe that imperfections in the copying of genes will always mean there is finite limit to human life. They claim that 125 years is the limit of human lifespan and the chance of a someone passing that is just one in 10,000. 'Further progress against infectious and chronic diseases may continue boosting average life expectancy, but not maximum lifespan' says Dr Jan Vijg, professor of genetics at the college.
