Since the passage of time is somewhat fluid in-game, do we even track characters' aging in a consistent way? More to the point, is it possible that characters could begin to feel the effects of aging later? Example: Say I make a human fighter with the background of a war veteran. He begins play being 49 years old (late-range middle age) and experiences no statistical change. In roleplay, I really drive the characterization of this man a la Clint Eastwood in Gran Turino. Four years pass in-game, however that works and is tracked, and my codger reaches old age at 53. Would he then experience any change to his stats?
