Nah just from experience.
Girls till they're 23/24 don't mind showing their age. Once they hit 25 they start having the same bday every year or forgetting their real age

Once they pass the 36th bday they realise they're not getting old, but maturing nicely and in an elegant way, so they're sort of proud of that and don't mind telling their real age so people can tell them "wow you look much younger".
