It's funny, even if Pokemon is still popular 50 years from now, Ash will probaly be like what? 15? There is though a small refernce though to Ash growing it up. In the Pokemon movie short (I forget the name, but its the one where Pikachu meets the Pichu brothers...) Ash claims at the end it has been 1 year sence they meet. So asumming Ash WAS ten at the start of his journey, this marks That he is ATLEAST eleven! Also, there are multiple points the the story, (Such as the Pokemon League and Contests Championships) that usually only come one a year. Still, I do find it both satifiting and creepy that Ash never ages. Then again, who would want Ash to be 21? If you do, please; do tell. AFter all, The first time Ash was first seen as a ten year old was in 1998! So he was born in like... 1988? Trust me, everyone would prefere if he was always ten over his real age of 21....
