I look like any 24 y/o. I don’t see what sort of data would suggest that rather loaded question. Do elaborate your reasoning and your bases.

Vibes and experience, no citation haha. we’re all friends here yo

Hm. Must be the excellent diet of predictable foods like frozen pizzas and energy drinks along with the our sedentary lifestyles we lead because the outside world is too loud and unpredictable that keeps us from ageing. Also us autistics are rarely stressed, not being able to participate in the economy truly puts weights off our shoulders. I guess ageing requires being alive, but that isn’t possible when you are dead to society.

Haha i see all what you’re doing, there, _,

I am indeed funny. Forgive me however. I might have written a snarky answer here, but I’ll try answering your query in earnest.

I have a developmental disability. This means that I developed and still develop in an uneven way. There are specifically diagnosed delays. While I don’t look particularly young, I act in very childish ways because the genes that regulate pruning as well as other processes are not functional, or limited in their functionality. I have not developed much since turning fourteen. This milestone happens to be around a decade old. This person you’re seeing answering your question is more or less embarrassingly a child and they have difficulties taking care of themself.

This is also obvious from my behaviour. I intone like a kid, I nag like a kid and I am interested in age-inappropriate topics. When I nine to ten I would watch programming for toddlers. I’d genuinely enjoy it. When I was nineteen I became interested in anime meant for middle schoolers and so on. To this day I have really odd expressions especially when I am happy or excited, those that you would expect from a hyped up fortnite kid.

People just happen to notice that. You may not look younger but you act like a child with autism and that makes people think you are younger.

I probably have both working for/against me in uncountable ways

Both what?
