When I was getting my associates degree in networking there was a guy in my cisco classes and my sql classes. Probably in his lat 50's early 60's. He's wheelchair bound and can only really move one of his fingers and his head. Has to have a nurse with him 24/7. He's been taking one class a semester for I think the past decade and he's finally almost done. Only a few classes left last I talked to him. I don't think he'll be able to do anything with the degree when he gets it but I admire his determination to finish it.
