If you're looking for something to keep your brain entertained as well as exercise your memory, I recommend speedsolving Rubik's cube. Learn the Fridrich method, which is basically solving the first two layers intuitively (lots to learn) and then applying 2 of 78 memorized algorithms for the last layer.
"Cubing" is my new hobby that I've now come back to after learning it years ago and taking a long break. I currently average about 20-30 seconds (on 3x3), sometimes less.

TRIPPY!
Was following a rabit hole a while ago after reading this and came across Group Theory:
en.wikipedia.org/wiki/Group_theory
check out the page, you have to see it
that led to Hermann Grassmann:
en.wikipedia.org/wiki/Hermann_Grassmann
"
In 1844, Grassmann published his masterpiece, his Die Lineale Ausdehnungslehre, ein neuer Zweig der Mathematik[1] [The Theory of Linear Extension, a New Branch of Mathematics], hereinafter denoted A1 and commonly referred to as the Ausdehnungslehre,[2] which translates as "theory of extension" or "theory of extensive magnitudes." Since A1 proposed a new foundation for all of mathematics, the work began with quite general definitions of a philosophical nature. Grassmann then showed that once geometry is put into the algebraic form he advocated, the number three has no privileged role as the number of spatial dimensions; the number of possible dimensions is in fact unbounded.
Fearnley-Sander (1979)] describes Grassmann's foundation of linear algebra as follows:[3]
