I've never understood this belief. There are many things I struggled with as a child that are very easy for me to understand now. For instance, calculus. I struggled barely passing my classes originally. A few years ago I decided that I really needed to know calculus so I bought a book and worked through all the problems. Not only was it not difficult but the whole thing just made logical sense; it was all straightforward.

I can believe there are some things that would take me longer as an adult to learn than if I were a child (a new language for instance) but origami folding wouldn't be one of them.

Calculus may have seemed easier because you actually learned a lot more than you thought you did in school. Just having been exposed to the ideas before may have allowed you to develop an intuition that you didn't have access to the first time around.
