IS ASH in his 40's

Ash is still 10 years old

People have theories for how
I believe in the ho-oh theory
that since when ash saw it in the first episode, ho-oh granted him the wish to be a pokemon trainer forever, thats why he never grows old または wins battles againt the elite four

Lol,no,he is 17.i bet he would have kids if he was 40.i laugh cause i imagine ash in his 40's.
