They don't have a care in the world

[alpacinou]

Hello

Can the expression "not a single care in the world" be used in the context of learning language?

Is this sentence correct? How about the register?

Children don’t have a single care in the world. They have free minds. That is not the case with adults whose minds are preoccupied with many responsibilities. So, children have less difficulty learning a new language.

I would say don't have a care in the world.

I would say don't have a care in the world.

Good point. "Single" is redundant.

Do you want to refer only to the adults whose minds are preoccupied with their many responsibilities or do you think there should be a comma after "adults"?

Subtle point. I need the comma.

It's biology. Humans are hard-wired to learn a language from birth to six. After that it becomes more difficult.
