Humans are unlikely to ever blow out more than 125 candles on their birthday cake, according to research that suggests that our lifespan has already hit its natural limit. The notion of extending the human lifespan has captured imaginations for millennia. But the researchers, writing in the journal Nature, describe how analysis of records from a number of international databases suggests there is a limit to human lifespan, and that we have already hit it. The apparent limit to human lifespan, the authors say, is not down to a set of biological processes specifically acting to call time on life. “While we don’t have demographic data supporting the idea that the maximum human lifespan is now increasing, that certainly doesn’t mean it’s impossible.”
