Take the classes and learn something new.
Computer skills are handy, programming, website development.
Learning new things keeps you young, and its not a waste of time. Times wasters are the ones that are on FB and Tiktokker all of the time when they could actually be using the knowledge on the internet to gain something in the brain.
I use the net to search for history, maps, beekeeping, fishing tactics, and other research. And, of course, learn lots of things on here.
