It was mentioned in an early issue of Catwoman that she is only 23 too.
I remember in an interview that Green Arrow is only 24. I'd prefer him to be somewhat older.
The protection of the universe is in the hands of youngsters these days.
Superman is 75, Batman is 74 and Robin is 73. Because they are not real.

Eh, nothing wrong with age as a character detail, though. Bart Simpson is supposed to be 10 years old and it puts a lot of his world into context.
Far as I know, the only confirmed ages are Superman at 22/27, and Wonder Woman at 23 in her book.
11/20: Zero, New Guardians, Batman '66, Harley Quinn, Miss Fury, X-Men Legacy, Daredevil, Wonder Woman, Supergirl
