Staying fit is so horribly hard in winter. Do you have means/opportunity for a video-game based fitness thing? I found that Wii Fit actually helps me a lot, surprisingly.

Irish step dance! I did that a small bit but never enough to really get good. I wish I had.

Re: food....hmmm. I don't have this *particular* issue with logging food, so I don't know if this recasting would help or hinder, but what about keeping track of menus? Like, "tonight's dinner was pasta with zucchini and chicken" or something? Essentially I'm wondering if calculated vagueness would help. But as I said, I don't have that particular issue set, so my suggestion might be useless.
