Can a human live to 140 years old? An analysis of biological limits and future possibilities

While the oldest verified person in history, Jeanne Calment, lived to 122 years old, scientific opinion is divided on whether her record is a permanent ceiling or merely a high-water mark waiting to be surpassed. A recent study using mathematical modeling suggested an absolute limit of 150 years, while other research posits that no fixed limit exists and advanced medical care could potentially extend maximal lifespan further. The question, "Can a human live to 140 years old?", forces us to confront our deepest biological constraints while considering the transformative potential of future technology.
