A recent piece in The New York Times by acclaimed science writer Ferris Jabr investigates the one thing we all try not to think about: How much time do we have on this planet?
According to Jabr, there are two types of longevity theorists — pessimists and optimists. Pessimists believe that life span is finite. According to their thinking, we’ve already touched the ceiling on human life, at 115 to 120 years. Optimists, meanwhile, view life span as still unexplored and possibly unlimited. Humans, they say, could live for hundreds of years.
