Next year I'll turn 60 and here in Alabama, USA, people 60 and over can go to the Community Colleges tuition free. I plan to take classes. Not for a degree, not even in just one area, I just want to be back to writing papers and doing homework.
I am a lifelong learner too! I also teach Community College, there are always interesting classes to take. I don't teach Art History, but if you spot one of those courses I recommend you give it a try.
Really love that your state offers classes at community college free of charge for people over 60, I am sure it's great for the young ones to have the perspectives of someone older. I live in Norway and here the vast majority of colleges are free for everyone, so I've had the benefit of both having older people in my classes (I remember very very fondly the 40-something who was in my English classes -- she was such a knowledgeable woman and it scares me more than a little bit that I am now about the same age she was back then) and being one of the older people myself. Though, most of my college classes as a 'real adult' (30+) have been online or what google translate wants to call 'collection-based'. Basically, you mostly study by yourself but then have a few times a year where you meet your fellow students and professors in meat-life. Very practical for older students with full-time or nearly full-time jobs, but it doesn't give as much chance to learn about life outside school as when you meet the same people every week for class and maybe eat lunch/study together outside of class as well.
