I have thought about this before. I have no intention of stopping, but I have a hard time picturing myself at 60, still writing fanfic. Hmm.

I think I would only be likely to stop if I didn't have any interesting fandoms or if there were some RL event that made it necessary for me. I'd probably then turn my creative energy into D&D stuff instead.

But right now, I can't imagine life without fanfic.
