Are their brains still fully developed? Do they have much life experience leading them to independence, financial breadth of knowledge, and well read and educated in real world experiences? Some maybe… most? Likely not… I don’t even understand what you’re arguing with.

I said they’re still child like in mind - their brains are not fully developed like that of most adults… that doesn’t mean they are 3 years old. A child by most definition is a child until 18. They’re not very much removed from that at 20… And until they’re 25-27 their biological chemistry isn’t even the same in brain and body… so… I don’t know if you just like arguing for the sake of arguing or have a problem with science or something?
