I'm the complete opposite. I'm convinced my brain has some kind of overly aggressive internal garbage collection. Knowledge/tools that I haven't derived utility/benefit from get purged. I will say that something I've book-learned in the past can be re-learned more rapidly if I run into that problem in the future, but it's grossly inefficient and of little benefit.
