Isn't grey streaks in the hair a side effect of the Lazarus Pits? And Tim Drake was 13 when he took over as Robin in "A Lonely Place of Dying" and is 16 now. So that counts for 3 years. And wasn't Jason Todd dead for a year before that? So wouldn't that make him 19 or 20? Plus there's Zero Hour and Hypertime now to, so maybe Jason Todd's 21 or 22.
