What don't I do. First off, I save everything I'm doing on my laptop and shut it down, and after that...
I have portable music with my mp3 player. I have my swords, nunchaku, and staffs to practice with, and without any distractions I can get some good practice in. I have my legos to play with and that's always fun. Then I have my chess boards, whether by myself or with someone they're always fun. And that's just inside. Outside, the skys the limit, though it's not always appreciated by the neighbors.
I can live without power quite happily.
