Batman Character Ages in the DCAU

Thought I would do an experiment to see how old everyone thinks that the Batman characters are throughout the different iterations in the DCAU.

Here's mine of the main characters.

Batman the Animated Series

Bruce Wayne/Batman- 30 Dick Grayson/Robin- 19 Commissioner Jim Gordon- 60 Alfred Pennyworth - 62 Barbara Gordon/Batgirl- 18

The New Batman Adventures

Bruce Wayne/Batman - 35 Tim Drake/Robin- 13 Barbara Gordon/Batgirl - 23 Alfred Pennyworth - 67 Commissioner Jim Gordon -65 Dick Grayson/Nightwing - 24

Batman Beyond-

Bruce Wayne- 77 Terry McGinnis - 16 Commissioner Barbara Gordon- 65 Tim Drake- 55

I really would like to see what everyone else thinks.
