Lifespan represents the maximum potential age humans could reach, while life expectancy is the average age people currently live to, which has been steadily increasing. Serious scientists are exploring ways to extend lifespan through medical advancements, with some even suggesting that the first person to live to 1,000 years old may already be alive. The debate continues regarding the optimal lifespan under ideal conditions, with estimates ranging from 110 to possibly 150 years.
