is it possible to add age without birth year?

Question

I'm using this to make a family tree for my sims 3 game. I want to know if it's possible to add age without needing a birth or death year, since that doesn't work in the sims. I want it to say how old they got

Answer 1

Personally I'd just write it in the Bio info. For example in the birth place or profession category, just write before or after the other info:  "age 24"

edit: just another idea, as it's only for a game, you could also just add the age after the character's name: "Georg, 58"
