Am I childish for still play outside?

I am 13 and shortly after moving to the city I am rn in 2023 I've always been playing outside with the friends I made in school. Hooliganing around the neighborhood, playing football in the nearby mount, playing tag (my fav), racing (we're racists), hide and seek, etc.
But there's these boys from high school 1st grade (10th grade in 'murica) who are also fwends and they said I am childish for still playing outside even tho I'm a teenager now. Since then what they said live rent free on my head
So... how old were you guys when you stopped doing outdoor activity of this sort? am I childish for still be playing outside?
