Returning to coding 10 years later. A lot has happened.

As you get older (I'm 80) your brain slows down. This is a well-known fact. The defence against this is to keep it active and learn a new skill.  I tried a new language (Spanish), but it turns out that if you are really bad at languages in your youth you are God-awfully bad in later years. So, I turned to something I did have a talent for - coding.
