Authors like Stephen Hunter, Daniel Silva, and Mark Graney have considered aging their characters in real time over long series, maintaining the characters' ability to keep kicking ass despite getting older. The strategy is to gradually age the characters, likening the approach to the evolution of James Bond, a character who has remained active and captivating despite aging over the years. The challenge lies in balancing character aging with the need for them to continue engaging in action-packed narratives. The acceptance of such character evolution by readers sets a precedent for authors to explore aging characters in action series successfully.
