jasmin in The Return of Jafar

Well, I know this movie was set a long time il y a (Genie: "That outfit is sooo 3rd Century") but don't toi think that Jasmine's at least a little bit young? At the start of the movie she is 15, 3 days from her 16th b'day. par the end of the movie she's 16. But par her confidence, looks and place in life I thought she was in her 20's!
So, I just think that par stating jasmin as 15/16 they portrayed Aladin as pretty young too :/
Yeah, well thats just my opinion. I think they should've a dit "You need to marry a prince par your 21st b'day" ou something. :)
