I also went back to school; I just took classes that I was interested in, and that would help me get a job (I had never had to work) and it was a lot of fun.
I wouldn't mind taking more classes...
There are certainly worse things to do with ones' life!
I enjoyed school, and would like to take a few more classes when I get some bucks ahead. Im thinking of taking some forensics courses so I can pick apart CSI.
