Is it possible to learn an academic subject so good you never forget it?

Here I am speaking about subjects that you won't be practicing regularly... I'm referring to theoretical subjects, things like biology, or psychology, or geography...

Typically, what I am thinking of when I say "subject" is something like a full exam. For example "Principles of Economics" or "Social Psychology", or "Principles of Marketing" or "History of Italian literature". Typically it would be a full exam worth of stuff, or even multiple exams.

So it's not something small like a poem that you can easily memorize by heart.

It's also not like maths that you can practice over and over again.

So I am wondering if it's possible to learn something like that in such a high quality way, that you get a full and deep understanding of it, and that you practically never forget it. Of course, it's not required that you can recite the whole textbook...

But I am wondering if it's possible to learn something so well, that even after 10 or 20 years of not dealing with it actively, you can still easily remember all the main concepts and all the fundamental ideas from it?
