Good for you ..never is too late to start studying again ....
About 20 years ago I was at Cambridge University (UK) doing lots of drinking when I should have been studying maths. I escaped with a degree and embarked on life that ignored everything I had learned up to then. Fast-forward 15 years to when I met my future wife, a Colombian. Shortly after the birth of our first child we moved to Colombia where I am the stay-at-home Dad. As a way to keep my brain active I started reviewing some of the old text-books from my university days that managed to avoid being discarded in the move across the pond. Mostly I'm looking at Analysis, although I've found other texts in my bookcase and online that cover things like Number Theory and Game Theory.
