Many gladiators were recruited or sold into the profession during their adolescence or early adulthood, typically ranging from late teens to their early thirties. These individuals underwent rigorous training and preparation before being allowed to participate in actual contests.
However, there were also cases of older individuals becoming gladiators. Some retired soldiers or athletes might turn to gladiatorial combat as a way to continue earning money or fame. It wasn't uncommon for experienced gladiators to fight well into their thirties or even forties, gaining significant recognition and status within the arena.
Gladiatorial combat was a dangerous and demanding profession, and the life expectancy of gladiators was generally short. Many sustained serious injuries that often led to death or disability. As a result, the average career span of a gladiator was relatively brief, and most likely peaked during their younger years.
