This morning Lisa challenged me to a contest to see who could lie flat on their back and rise to their feet, unaided, the fastest. She tried cheating, of course, and seeing my victory in doubt I sped up - and slipped on vinyl flooring. I went headfirst into the edge of our formidable dining room table, scraped my left shoulder, and skinned and bruised my knee.
While the knot on my forehead was the immediate concern, the knee swelled quickly. But after some ice, rest, and then some activity, it felt okay.
