I know it's flavor text, but I'm curious anyway. As far as I know it goes

Newborn (0-4999)
Infantile (5000-9,999)
Young (10,000-49,999)
Moderate (50,000-?)
Old (200,000-?) *My father played a game that went on for a really long time

What comes after "Old"? Where can I find the textfiles to mess with this? (assuming there are any and that it isn't hard-coded)
