I wanted to make Brooke's daughter be a middle aged woman (37) that was scamming Brooke (like Esther in that Orphan movie) but the game wouldn't let me.
According to Wikipedia, the oldest person to ever live was 122 years old. There could be a feature that if you set a girl's age, like Brooke, to 123 years she instantly dies never to be seen in you game again.
