Where do you get all your ideas?

Pretty much from everywhere, but a high percentage of ideas are derived from what I read. My wife jokes that the postman heaves a sigh of relief after leaving our house, because we subscribe to so many periodicals. And yes, I read hard copy because I’d rather not waste computer time on reading, when there are times I can read when I’m not near the computer, and I hate reading anything off a cell-phone screen. Often, I’ll get a delayed reaction, as for example, I had read about the fascinating behavior of active galactic nuclei in an astronomy publication… and that fit right in with something in my forthcoming SF novel — Solar Express, except I didn’t realize it immediately, but later when I was taking my early morning walk with the energetic Aussie-Saluki.
