AS a 45+ years old student, I can relate a lot to the spacing thing. Gone are the days where I could memorize in a matter of hours, now it takes weeks. Memory as a "rebuilding" mechanism is also so true. I have to understand everything I study in minute details, else my memory just bumps on the slightest not-yet-understood thing. It's excruciatingly painful 'cos it needs a lot of work. (I have a background in compsci and now I'm studying data sciences at master level, which means : maths, maths, maths and maths and basically no compsci; I like maths, but that's quite a bit more involved than 20 years ago and 10000% more than 2 years ago when I was a PM :-)))
