I like reading, but not generally fiction, mainly science and history books. I like writing too, and I'm planning to be a professional author one day. I'm fascinated by anything scientific. I don't have many interests beyond that, apart from chatting to friends on IRC and subjecting the unwary denizens of Amiga.org to my opinions. Computing apart from that isn't fun any more.
Wayne, I'd stick with the aircraft hobby if you can afford it. If you enjoy it, all the better, but it will get you places, and I don't just mean physically. Things like that are always good on a resumé, and who knows, you could launch it into a career. Certainly it's more eyecatching than "Uh, I read books."
