Black ice

Options
And this is the reason I hate winter.

I was going to work yesterday and slipped and fell on black ice. It was so slippery that the person who was trying to help me up struggled to keep his balance. That's how slick it was.

I can't exercise so I need support on ideas how to keep my calorie count in check because my left knee is hurting. I'm going for an x-ray later today to make sure I didn't damage it too much The doctor seemed to think it maybe just tissue damage but he wants an X-ray just for piece of mind I guess.

Any ideas? I can still move just slowly
